Forester Chainsaw Tooth 9″ Brush Blade – Best Brush Cutter Blade For Small Trees

Affiliate links and images placed from the Amazon Product Advertising API on 2022-11-21

Forester is a dependable American brand from Wilkes Barre, which makes its products in China. It offers legitimate, top-notch replacement components for popular power tool names, such as STIHL and Husqvarna. In my opinion, it is the premier manufacturer of powerful 9” saw-style blades for brushcutters.

This item is exceptionally solid because it is designed to be able to tolerate up to 10,000 revolutions per minute. It has 20 sharp full-chisel teeth similar to those of a harsh chainsaw chain for cutting hardwood. Thus, you can utilize it to cut nearly anything apart from large trees and, obviously, rocks.

This one is very easy to sharpen since it needs two to three even strokes for each tooth each time you refill the fuel tank. I tried this blade on a large choke cherry bush with lots of substantial trunks growing close to each other.

This item proved to be just what I needed for my 32cc STIHL brush cutter; I didn’t notice any lack of sharpness until I was done with the large, wet bush. With this product, if you need to cut down several bushes in a row, you can easily replace the blade (there are two in one package) and keep going.

Furthermore, the kit also includes two round files for accurate sharpening, which makes it a great buy if you are looking for strong cutting power to tackle thick bushes.

  • Two blades per pack;
  • Quality round files included;
  • Heavy-duty performance (up to 10,000 RPM);
  • Affordable and comprehensive kit;
  • Full-chisel teeth.

ATIE Carbide Tip Brush Cutter Blade – Runner-Up

Affiliate links and images placed from the Amazon Product Advertising API on 2022-11-21

The ATIE 80T is a great alternative to the RENEGADE 8’’ carbide-teeth blade and has approximately the same performance of 80 brazed-welded teeth, offering great longevity and cutting strength. The only downside is that the carbide tips may not be as long lasting as they are made up of only basic materials.

On the other hand, there are 80 blades instead of 60, meaning a larger cutting area. Since I don’t have the proper resources to compare the sturdiness of both alloys and designs, my personal experience tells me they are both extremely solid and rarely require sharpening.

Furthermore, it is compatible with both 1” and 20mm drives, allowing you to use it with string trimmers and brushcutters. However, I wouldn’t advise it for line trimmers as they are not powerful enough to generate the optimal RPM for this product, requiring it to rotate quickly for optimal performance.

The set includes two weed eater blades with protective plastic covers for the teeth, making it easy to transport. Therefore, you can purchase this model without worry if the RENEGADE 8” is not available.

  • Two items in the package;
  • 80 teeth for lower friction and higher longevity;
  • Universal 25.4 and 20 mm fit;
  • Good for most light and medium tasks.

RENEGADE BLADE 2pk-8″-80t – Extra-Durable Weed Eater Brush Blade

Affiliate links and images placed from the Amazon Product Advertising API on 2022-11-21

This brush cutting blade for weedeater is not made by a well-known brand, yet it surpasses all other products for its versatility, durability, and cutting ability. Though it costs a bit more than similar models, the extra money is worth it for the improved performance.

This blade features a 203mm plate crafted from a sturdy yet lightweight steel, with holes in the surface to avoid overheating and make it lighter. In addition, it contains 60 teeth made from a proprietary carbide alloy that is 10 times sturdier than steel, so it won’t dull as quickly either.

These teeth are securely welded into slots, making it nearly impossible to remove them unless you try to cut through granite. This alloy consists of tungsten and 10 other alloys, such as chromium, vanadium, boron, and titanium, which give the teeth greater longevity and sharpness.

I recommend this product to both home gardeners and professionals who need something strong to take on most gardening tasks, including cutting grass, brushwood, and thin branches. Its holes and carbide teeth make it suitable for tough work in dusty conditions, where open mechanical parts experience high wear and tear.

If you accidentally hit a large rock, you may lose a tooth (it’s just the way carbide works), but the balance won’t be affected as there are still 59 teeth left. I use this blade for almost everything except cutting thicker trees. For that, you can find better options below.

  • Heavy-duty teeth made of carbide alloy;
  • Lightweight steel plate with holes against overheating;
  • Great for most purposes;
  • The reusable protective seal provided;
  • Requires rare sharpening.

RENEGADE BLADE green”VIPER” / HYBRID – Best Weed Water Blade with Combined Teeth

Affiliate links and images placed from the Amazon Product Advertising API on 2022-11-21

The previous item was the first product by RENEGADE BLADE that I’ve tested. Once I needed to buy a new one but didn’t want to experiment with other brands, I had a lot of work to do rather fast. Unfortunately, my favorite one wasn’t available, but I noticed that the entire line of the brand has carbide teeth. Without thinking long, I ordered the 44t, and it appeared to be a good one.

This cutter blade has a bit fewer teeth to free up a few spaces for angled sharpened cavities. This feature makes cutting wood a bit more difficult but adds up power against weeds. Some thick stems get into cavities if you wave the machine fast enough and break with ease.

The teeth of this model are also a bit smaller for achieving lower friction. In addition, they are welded deeply into the plate, which makes it even harder to cheap them. This is a perfect budget carbide option with extra power against thick weeds. The manufacturer recommends using it at around 3,500 RPM, but it actually works well at higher speeds too. It’s a great option for medium-strength gasoline machines.

  • Multi-purpose low-friction carbide teeth;
  • Sharpened cavities for thick weeds;
  • Good for medium-powered machines;
  • Extra-durable design;
  • Rare sharpening required.

Rotary Razor Max JM777 – Best for Medium Brushwood

Affiliate links and images placed from the Amazon Product Advertising API on 2022-11-21

JM777 is probably the best alternative to Forester 9’’ in case you need a less powerful solution. This one does an excellent job on saplings and medium-density brushwood. Due to a smaller diameter and high durability (up to 10,000 RPM), you can cut wood with high efficiency. However, the teeth will get dull a bit faster than the 9-inch’s Forester because there are just 14 of them. On the other hand, it’s a bit easier to sharpen them.

It’s a good solution for heavy brush cutting at high speeds. At the same time, you can use it for effective grass trimming as well if you don’t want to swap blades during the day. The center hole has a standard 1” diameter, which is suitable for the vast majority of brush trimmers. You should also know that there’s a mistake in the description of the item and you need a 1/8″ file for sharpening instead of the standard 3/16”. Proper sharpening will make it furious against brushwood.

ATIE 3 Teeth Steel Brush Cutter Blade – Best Star-Shaped Model

Affiliate links and images placed from the Amazon Product Advertising API on 2022-11-21

Here is one more excellent product by ATIE. This 10” blade has 3 large sharpened knives that have a double-slope cutting surface. Of course, for most of the time, only the 10mm part of the blade actually cuts, while the rest couple of inches remain clean. On the other hand, they become very effective when you start waving your cutter fast enough from side to side. In addition, they reduce the probability of tall grass warping around the gear head as it’s rather high for star-shaped edges.

Due to the large diameter and thick 3mm plate, you can also apply this grass cutter blade for fast grass mulching. It behaves perfectly well on high RPM, and it’s rather hard to damage as the paddles are really sturdy. I recommend this one for dense weeds and grass, but I know people who cut down large brushwood with this one too.

I’m sure that chisel blades are much better for that, but you can try these as well, if you really want to. It’s a pleasure to sharpen these large knives anyway! You can use any flat files to achieve a bright shine and repeat it thousands of times.

  • Ultra-sturdy 3mm-thick steel;
  • Easy to sharpen with a flat file;
  • Good for dense grass and thin brushes;
  • Low damage rate;
  • Universal 1” and 20mm fit.

Wisamic 10 inch 80T Carbide Blade – Best Weed Eater Blade 2 Pack

Affiliate links and images placed from the Amazon Product Advertising API on 2022-11-21

This affordable blade by Wisamic offers an excellent ability for cutting medium-thickness brushwood, tall grass, and water weeds. The 80 teeth of the item are made of standard 2-component Tungsten carbide alloy, which remains sharp around 5-8 times longer than average steel edges. The teeth are welded into notches for lower chipping probability. Nevertheless, it’s not likely to stay like new after a few hits on rocks or thick hardwood.

I figured out that the best application of this product is to cut 3” stuff and smaller to avoid overheating and quicker blunting. Tests on thin hardwood were successful but not as good as when I used RENEGADE BLADE. For average brush and woody weeds – it’s almost perfect. If you’re still skeptical about clear carbide cutting abilities, you should try this weed eater brush cutter blade. The package includes washers for easy installation on both 1” and 20mm arbor bores.

  • Two washers are included;
  • Good for medium-hardness wood and dense woody weeds;
  • Stays sharp longer than steel;
  • Universal fit.

Brush Cutter Blades Buyer’s Guide

The market is overflowing with offers by numerous brands, so it’s a tough mission to make the right choice, especially if you’re a newbie. Read this section to know the difference between the existing types and to know what brands you should be looking for. There are 3 most commonly used types of blades – chisel, knife, and smasher.

Knife Blades

Knife blades can have from 2 to 40 sharp knife edges. This is the cheapest, most common, and generally most effective blade type. In most cases, the cutters are equipped with one by default. Such blades are usually very good at cutting dense weeds, watery plants, and brushwood (not all models).

The number of knives defines cutting ability and, what is more important, the actual time of effective spinning. There are several simple things that you should remember. Rectangular and star-shaped nozzles with 2-3 large knives are much easier to sharpen. Besides, they blunt much slower. On the other hand, I’ve noticed that these models can wrap strong tall grass around the gear head if you don’t apply enough traction.

Blades with 4 and more sharp knives are less likely to wrap the gear head as they keep the vegetation around the outer contour. It’s always better to have both types. Or you can train a safe cutting technique to avoid swapping the blades too often.

If you need mulching capabilities, you have to look for rectangular and star-shaped nozzles as they have the largest knife surface. The rounded shape is totally useless for mulching, so don’t waste your time trying to mulch with it.

Chisel Blades

All of these blades are circular but may have a different number of teeth and chisel type. Some of them provide a shaving effect, while the others are somewhat similar to a chainsaw chain effect. Some items even have a chainsaw welded between discs.

best, brush, cutter, blades, weed

Due to high cutting capabilities, I recommend you use them for cutting hardwood and woody weeds. At the same time, these blades are usually very difficult to sharpen because of their complicated design. They also have a heavy kickback action if you cut something deep.

On the other hand, their cutting ability is very high if you don’t try to cut something thicker than 4 inches. In addition, chisel blades can pull themselves into the wood without bouncing away.

These blades can have steel teeth with or without offset (the first is much better), or chainsaw chisel. They have extreme wood cutting power, but the kickback and sharpening are significant as well.


These though nozzles don’t have sharp edges as they rely on the thickness and raw smashing action. You don’t have to sharpen them so the maintenance is very simple. Just clean the clippings off and go. Despite their fierce appearance, these nozzles can be used only for mulching grass and water weeds. I also don’t recommend them for tall weeds as they can easily wrap around the gear head and slow you down.

Less Common Types

Mulching blades are designed for furious mulching action and can only be used with the most powerful machines.

They can also throw prunings with high force, so you can use them only wearing full-body protective gear. The vibrations they cause are also too heavy for average machines;

Tungsten carbide teeth – being made of one of the strongest alloys on the market, these circular blades don’t have to be sharpened as frequently as average models. This is my favorite type, as it’s universal and durable.

Diameter Effects

My experience proves that diameter doesn’t affect the cutting ability too much. You should understand that the most important part is the cutting edge that is always very short. The larger diameter of a circular blade boosts the cutting edge size, which can be effective when you cut grass and weeds, but nothing else. The majority of models have more or less the same diameter.

Brush Cutter vs. String Trimmer

On first sight, brushcutters and string trimmers are similar devices. I was very disappointed when I bought an average line trimmer around 9 years ago and read an article about brushcutters a while ago. My disappointment was huge because I figured out that the second type of machine is much more powerful and combines the capabilities of both types. But let’s dig a bit deeper.

? Power Versatility

All string trimmers are equipped with less powerful engines than brushcutters. Manufacturers make line trimmers only for soft grass and weed trimming jobs, so they don’t put the power needed for cutting bushes and trees into their devices. Still, the design of both power tools is almost the same, and it’s very hard to distinguish one from another if you’re new to the topic.

Ok, now you know that line trimmers are not powerful enough for doing something more difficult. On the contrary, brushcutters can be equipped with heavy-duty 2 and even 4-stroke engines, depending on the purpose of a particular model. They also have stronger chassis and transmissions in order to withstand the tension created by the friction between wood and the blade.

While less power means less versatility, more power lets you adjust your tool to a wider range of tasks. That’s why the lines of cutting nozzles for brushcutters are so diverse. You can install an average nozzle with nylon strings to trim hard-to-reach areas of your lawn, or put on a circular saw-type blade and trim down brushwood without any difficulties.

If you ask me, “Can I convert a line trimmer into a brush cutter?” I’d answer “yes” too. However, you cannot expect it to be as powerful and versatile anyway. over, you will reduce your line trimmer’s longevity if you try to use it against too dense vegetation.

? Disadvantages?

power can be a disadvantage too, but only if you don’t actually know what you need. Brushcutters are usually a bit more expensive and entail higher maintenance costs. By that, I mean more expenses on power sources as heavier engines consume notably more fuel or electricity. Besides, you need a bit more muscles to carry an average cutter. It’s a small thing, but it can be critical for someone anyway.

Finally, cutter blades are more dangerous and require you to be more careful while operating. While a nylon string cannot make deep cuts through your skin, a blade can easily cut off your fingers or do something worse. It’s not really a disadvantage, but I don’t recommend you to operate this device if you’re not sure that you can follow all the safety measures.

? Do You Need Brush Cutting Blade?

I’m strongly convinced that having a brush cutter with a descent blade is a must for any gardener. I also don’t see any reasons for purchasing a less powerful trimmer and wasting money on a conversion kit and more frequent motor repair works. Using a blade with a trusted brushcutter, you can do heavier stuff and be sure that your tool won’t break or overheat in the middle of the day.


Plus, you can downgrade to a nylon trimmer anytime. Paying a bit more at the start, you save up on solving potential problems in the future.

FAQ on Brush Cutter Blades

In this section, I answered all the most frequently asked questions of my readers about brushcutters and blades. If something remains unclear, you’re welcome to let me know in the Комментарии и мнения владельцев.

What is a brush cutter blade?

Unlike a nylon string nozzle, a brush cutter blade is a solid metal item that’s stamped or lasered from thin pieces of steel. There’s a variety of shapes on the market with a variable number of cutting edges (from 2 to ~40). Each shape has both pros and cons, so you have to be as attentive as possible to match the type and your purposes.

What is the difference between a grass cutter and a brush cutter?

An average grass cutter is significantly smaller and lighter than a brush cutter. These gardening devices are designed for trimming your lawn in places that cannot be reached by a mower. A brushcutter is equipped with a more powerful unit and can help you get rid of denser vegetation.

Can you use a brush cutter to cut grass?

While a string cutter is too weak to cut brushwood, a brushcutter blade can do it all if you choose the right model. Fortunately for your budget, you can purchase a powerful brushcutter and use it for both grass trimming and brushwood works. All you need to do is ensure that the model you want to buy is compatible with nylon trimmer heads and the needed blade types. This way, you can really save up a bit and buy one tool instead of two.

How thick can a brush cutter cut?

While an average nylon cutter can cut only through lawn grass and tall grass, a brushcutter is powerful enough to cut really dense vegetation, including brushwood and even thin tree trunks. However, it’s not a chainsaw, so you should be careful and avoid touching trunks that are above 4 inches in diameter. I also don’t recommend you cut hardwood with this blade as a kickback may damage the cutter and even the transmission of your tool. Your tool’s cutting capabilities also depend on the sharpness of your blade, so you have to check it before each session to be effective and avoid traumatism.

How to sharpen a brush cutter blade?

  • Gather the gear – you need a workbench, clean rag, bucket of soapy water, wire brush, metal file (or a sharpening machine), oil for lubrication;
  • Make sure that the device won’t start all of a sudden;
  • Mark the bottom side of the blade to put it back properly;
  • Carefully remove the blade;
  • Clear the blade of clippers and mud, then wash it in the bucket of soapy water, and dry with a clean rug;
  • Wear protective gear;
  • Use a sharpening machine or make manual strokes with a metal file to achieve a bright shine on the cutting edge;
  • Put the blade back on your brush cutter.

Cut Fast

Now you see how important it is to tell brush cutter blade types and string cutters. Before making an order, you should make sure that you select a blade with the right properties. It may also happen that you need more than one blade for different gardening needs.

Have you already used brush cutter blades before? Which models have you tried? I’ll be glad to see you sharing your opinion in the Комментарии и мнения владельцев section below. If you have any questions regarding this topic, you’re welcome to ask them there too. I usually reply quickly.

Before You Buy a Brush Cutter

A complete brush cutter can be an expensive, heavy-duty machine. Handheld brush cutters are heavier, more powerful, and cost two to three times more than an average weedwacker or cordless string trimmer. Depending on how heavy the brush needing cutting is, plenty of attachments and adapters can help you do the job with other tools in your shed.

High-quality string trimmers can knock down patches of dense weeds on occasion, and they see regular use grooming the yard every week or so. A good solution could be to purchase a brush-cutter head for an existing string trimmer. But if the weeds are extra heavy, the area is large, and the chore occurs frequently, it makes sense to invest in a dedicated brush cutter.

Types of Brush Cutters

Buying a new machine is a long-term investment no one should take lightly. Of course, it’s wise to buy quality tools for many years of dependable use. However, it is equally important to choose the right type of brush cutter for a property. An undersized machine wastes time, while an oversized machine wastes money and space. Read on to learn more about the different kinds of brush cutters and how they work.

String Trimmer Conversion

Instead of buying a new machine, you can simply convert a string trimmer into a brush cutter. Most string trimmers have motors between 20 and 30cc, which is not suitable for daily use as a brush cutter, but adequate for occasional heavy use. For example, use them to cut brush for a few hours, once a month.

There are two ways to convert from a string trimmer head to a rigid brush cutting head. The simplest is to use a powerhead with changeable attachments. These machines have a short drive shaft and a quick-connection system for easily switching from tool to tool in a matter of seconds. String trimmer and brush cutter attachments are just two of many attachments that powerheads can operate.

Converting a fixed string trimmer into a brush cutter requires an adapter. The adapter is unique for each brand of trimmer, but nearly all brands offer one. It takes 5 minutes or less with simple hand tools to remove the trimmer line spool and replace it with a brush-cutting head.

There are four basic types of brush cutter heads:

  • Knife blades are the most common. They use a sharpened front edge to slice through weeds. Choose knife blades, either a disc knife or tri-knife, for general purpose brush cutting. They are inexpensive and long-lasting.
  • Chisel knives are smaller and more aggressive than knife blades. These include the circular saw and chainsaw types. They work very well on heavier brush and small saplings but require larger engines, around 30cc and bigger, to work efficiently.
  • Smasher blades, also called flails, use thin edges and high velocity to smash through vegetation. These are not suitable for heavy, woody material, but work quite well on tall weedy grass.
  • Mulching blades look like knife blades, however, the blade tips bend at a nearly 90-degree angle. These are not common and are best for grinding up weeds, leaves, and branches.


If you care for a large suburban or rural property, a handheld brush cutter might be right for you. Handheld brush cutters efficiently take down heavy weeds and thick brush areas that are not accessible by a mower. A handheld brush cutter looks like a string trimmer, only it uses a specialized brush cutting head. In fact, it is possible to retrofit a string trimmer with a brush-cutting head.

Brush-cutting heads use heavy-duty trimmer string, rigid flails, or a circular saw-type blade to cut through woody material cleanly, quickly, and efficiently. Handheld electric brush cutters and gas brush cutters with engines smaller than 40cc work well for smaller jobs, like cleaning up a vegetable garden at the end of the season. For larger areas and more aggressive cutting capability, choose a gas-powered brush cutter with an engine larger than 40cc. These heavy-duty models can cut through saplings up to 2 inches thick.

5 Best Brush Cutter || Brush Cutters In 2023 || Buying Guide


Hobby farmers and other small acreage owners choose walk-behind brush cutters for occasional maintenance of fields and pastures up to an acre. Walk-behind brush cutters have heavy-duty rotary mowers, sometimes called rough-cut mowers. These machines can cut down tall, coarse, thick grass, weeds, and weedy shrubs. Some can cut down saplings up to 2 inches in diameter or larger.

Walk-behind brush cutters are single-purpose machines, but brush cutter attachments are available for walk-behind tractors. Some lightweight models are string trimmers on wheels, but most walk-behinds are much more robust, with heavy gauge metal parts that help them grind through thick, weedy areas. They are self-propelled, with rear-mounted engines and large rear pneumatic tires. This design allows the forward mower deck to easily glide up over tall vegetation.


Farmers and managers of large-acreage properties choose tow-behind brush cutters for regular maintenance of trails, large fields, wildlife food plots, roadside areas, and utility rights-of-way. Tow-behind brush cutters, also known as brush hogs, are large rotary mowers that owners pull behind tractors or ATVs.

Some tow-behind brush cutters have their own engine that engages the blade while the user drives over the area to cut. Other tow-behinds need the tow vehicle to supply the power. They connect to the towing vehicle’s power take off (PTO) by a drive shaft that turns the mower blade.

What to Consider When Choosing the Best Brush Cutter

There are several factors to consider while shopping for a brush cutter. If shopping for handheld models, you can go with a powerful cordless electric or a long-lasting gas-powered model. Repeat use for cutting thick vines and woody brush requires more power than mowing tall grass. Ahead, learn about the factors that should drive buying decisions.

Gas vs. Electric

Handheld brush cutters come with gas or electric power; there are no electric models in the other types of brush cutters. Gas-powered cutters provide plenty of power and extended cutting time. Electric brush cutters operate quietly, keep the air clean, and eliminate cost, handling, and storage of liquid fuels.

Electric brush cutters work great for mowing down an overgrown vegetable garden at season’s end or maintaining small natural areas that are not regularly mowed. Electric is an especially good choice if the tool is only used a few times a year because it eliminates the worry over stored fuel going bad. Power and battery life both limit the use of electric brush cutters on larger properties.

Although a few 4-cycle models are available, most handheld models feature 2-cycle engines that require mixed fuel (2-cycle oil mixed into the gasoline). That adds a layer of preparation time and expense. The 4-cycle alternatives are heavier, which increases user fatigue, but adds power and pollutes less than 2-cycle models.

Motor Power

Power translates directly to working ability. A more powerful brush cutter cuts faster and more smoothly than its less-powerful competitor. Increased power helps where the conditions become more adverse, such as thicker weeds and brush or uneven terrain. When all else is equal, the more powerful machine is more capable.

Cordless electric brush cutters measure power in volts (V) and are rated between 18 and 84V. Gas-powered engines measure in cubic centimeters of displacement (cc). Handheld brush cutters range from 24 to 50cc. Handheld brush cutters with power over 56V or 35cc are considered heavy duty.

Walk-behind brush cutters and tow-behind cutters with their own engines normally list the engine size in horsepower (HP), although some manufacturers may show it in cc. There are approximately 14cc per 1 HP. You can easily convert cc to HP for an equal comparison (cc/14 = HP.) Most walk-behinds produce between 11 and 20 HP.

Tow-behind brush cutters that run via power take-off (PTO) need enough horsepower to run efficiently. Consult the tractor or ATV manufacturer’s information to learn how much horsepower a PTO supplies. The rule of thumb is that for every foot of cutter width, the PTO must supply 5 HP. A 5-foot brush cutter needs about 25 HP from the PTO.

Cutting Width

The cutting width is the width of a single pass with the brush cutter. It determines both how quickly a cutter can complete the work, and how much space the machine requires for access to the site. Handhelds range from 9 to 18 inches, walk-behinds are 24 to 26 inches, and tow-behind cutters range from 4 to 15 feet.

Wider cutters use more power, and can more easily bog down in dense vegetation. Narrow models are slower. Tow-behind brush cutters should cut wider than the width of the tractor; otherwise, the tractor will drive over some vegetation twice before the mower passes over it. Also consider the width of narrow access points the machine must pass, such as gates or closely growing trees.

Walk-behind and tow-behind brush cutters come with heavy gauge steel housing, rugged pneumatic tires, and powerful engines that hold up in rough working conditions. Handheld brush cutters are more of a gradient from light-duty string trimmers to powerful brush cutting machines. For optimal durability, use these machines to do the tasks for which they are best suited.

When converted with brush cutting heads, string trimmers with engines between 24 and 35cc are adequate for limited use on thick grass and tall weeds. Heavy-duty string trimmers with larger engines can be converted for cutting thick weeds, woody vines, and small saplings. True handheld brush cutters, with powerful 40 to 50cc engines, can extend to the cutting of thick, dense, woody vegetation.


Tools that perform multiple tasks offer great value. Both handheld and walk-behind brush cutters are made as dedicated pieces of equipment, but most owners only use them a few times each year. Consider buying brush cutter attachments for devices that perform other lawn-care tasks.

The benefit of converting a string trimmer to a brush cutter by changing the head is that the extra head takes up virtually no storage space and extends the usefulness of existing equipment. It only takes a few minutes and simple hand tools to remove the string trimmer head from the end of the shaft and replace it with a brush-cutter head.

Handheld powerheads run lots of different tools, including string trimmers, lawn edgers, pole saws, hedge trimmers, brush cutters, and more. Powerheads feature quick-change shafts that only take a few seconds to switch between devices. Powerheads are more powerful than basic string trimmers and save the owner hundreds of dollars or more by using one engine for all needs.

Similarly, walk-behind tractors are powerheads that can do far more work than dedicated brush cutters. A walk-behind tractor lets the owner switch from brush cutter to a rototiller, snow blower, firewood splitter, pressure washer, and many other useful implements.

Universal Attachments

Anyone going the multiuse route should look closely at how the powerhead attaches to the cutter. Some large brands use proprietary attachment systems, which might work well, but tie the owner to that specific manufacturer. All future purchases also must feature the same attachment system. You can find good value in non-proprietary, or universal, attachment systems that interface with virtually all similar devices.

With all this in mind, some of the best handheld and adaptable brush-cutting products can help you clean up those overgrown corners. For a new handheld brush cutter that also can edge the driveway, check this list. If you have an excellent string trimmer and want to give it a brush-cutting upgrade, one of these products can help.

ATIE 8″ 80T Carbide Tip Brush Blade

The ATIE 8” Carbide Tip Brush Blade is especially well suited for cutting down stands of saplings and thick, woody shrubs.

With a 1-inch (20mm) arbor, it fits most string trimmers.

This blade is larger than some fixed brush cutter blades at 12-inches across and 3 mm thick. Users should sharpen the knife edges periodically for the best results. Be aware this blade is heavier than others, so consider the weight on the tool and using a shoulder strap for added support while cutting brush.

Oregon 20-108 Platinum Gatorline.155-Inch Trimmer

Oregon 20-108 Platinum Gatorline Trimmer Line.155-Inch features a twisted line profile for maximum cutting-edge exposure, minimum wind resistance, and excellent durability. Its hard exterior holds up well to high temperatures and impacts with hard objects. A braided line also makes less noise than other line profiles. This thick, heavy-duty trimmer line is best paired with a powerful brush cutter, greater than 35cc, for the best results.

Be careful not to add twists to the line while loading it onto the spool as that stresses the filament and can lead to early breakage. To prevent bogging down the trimmer, use this line only with strong trimmers 35cc and larger.

Husqvarna 17″ 2 Cycle Gas Powered String Trimmer

The Husqvarna gas-powered brush cutter draws its considerable power from a two-stroke gas engine. It’s not the lightest power tool at 16 pounds, but it makes up for the weight with an ergonomic grip and an impressive motor that helps to cut through dense overgrowth. The broad 17-inch trimming radius allows users to trim the yard in a hurry, and it has a simple bump-feed system to extend the trimming line when necessary.

The curved shaft design of this gas-powered brush cutter helps the Husqvarna to be more maneuverable and balanced so users have an easier time handling the power tool while they work. This gas brush cutter also has an automatic emergency stop feature that halts the movement of the trimmer string when the trigger is released, making this model even more user-friendly.

How We Chose the Best Brush Cutters

Given how easy it can be to convert an existing trimmer into a brush-cutting machine, we recommended a majority of blade options that work with a buyer’s existing tools to create an affordable brush cutter that can cut anywhere from thick grass to twisty vines depending on the base machine. Versatility is an important consideration for those who have the budget—or space—for only one trimming and brush-cutting tool

Of the blades, we gravitated toward those with a universal fit, looking to provide a range of options that will accommodate gas and electric trimmers. Whether looking at the blade or the full machine, foremost was durability. Blades, trimmers, or string have to hold up to some thick brush and stems to work as they should, so the majority of our top picks include a number of heavy-duty steel and even carbide blades that will hold up with average use.


Q: How do you use a brush cutter?

Always operate the blade parallel to the ground. Because the blade spins counterclockwise, cut with the left side to avoid kickback. Use a brush cutter with a blade with fewer than eight teeth and a long sweeping motion to cut grass. For tall, woody shrubs, use a tri-blade. Begin with the blade at waist height and lower the blade onto the material. Using a circular saw blade, only cut saplings 2-inches in diameter and smaller. Use a chainsaw for larger trees.

Always be aware of others in the area who might be harmed by flying debris. Wear hearing protection, safety glasses, work gloves, long pants, and work boots to protect yourself.

Q: How do you sharpen a brush cutter blade?

Sharpen the steel brush cutter blades with either an angle grinder or a bench grinder. If using a bench grinder, hold the blade edge at a 45-degree angle to the grinder. Press the blade steadily against the grinder as you slowly work the blade across the grinder from its center to the edge. Flip the blade and sharpen the other edge. If using an angle grinder, the process is similar, except the blade is clamped in a vice and the grinder moves across the blade.

Q: What type of engines do brush cutters use?

Handheld brush cutters use electric motors, 2-cycle gas engines, or 4-cycle gas engines. Walk-behind and tow-behind brush cutters use gas engines.
