How to use a gasoline grass trimmer

grass trimmer. Types and equipment. Work and how to choose. Safety

Garden equipment about, which will be discussed, consists of four main elements: the engine (electric or gasoline), a long boom, control handles, cutting head. Because of the differences in translation, these devices often appear under different names: grass trimmer, grass mower, lawn mower, electric lawn mower, electric mower, haymower and even lawn mower. Because of this there is confusion. Lawn mower. a device for lawn care, the main purpose is to maintain a neat appearance of the lawn.

The term “electric lawn mower” refers to two types of engines. gasoline and electric, which is also not quite right. In fact, all types of grass trimmers more logically called trimmers, which are divided into electric (electric mowers), gasoline (brush cutters or lawn mowers) and battery-powered.

There should also be no misconception that a grass trimmer is a tool for creating a decorative lawn. Mow the area inaccessible to the lawnmower trimmer can. That said, you can hardly mow the lawn evenly with a grass trimmer. Lawns mowed in this way will be inferior in appearance to the results of the work with a wheeled mower. But mowing weeds with a trimmer can be easy and enjoyable.

Technique of work with a fishing line and a disc

The technique of working with a string trimmer and a disc has some differences. So, the line for the trimmer cuts the grass at the very end, but if you move too fast, the entire length is engaged. As a result, the stems are not cut, and the grass winds up on the cord, which overloads the engine. You should therefore choose the optimum speed. Also, mowing tall and tough grass consumes trimmer lines faster than mowing lawns.

For your information! If you want to mow a hill, the hilltop should always be on the right. You need to go up gradually to the same distance as the width of the swath.

There are a few simple recommendations, the implementation of which will make mowing more effective and efficient.

  • Trimmers with the engine at the bottom are convenient for mowing garden paths, flowerbeds and edges of lawns. The plane of rotation of the coil of such a device can be placed perpendicular to the ground.
  • Mow dense thickets, large weeds, bushes with discs or special attachments.
  • When clearing large areas, the device must be tilted to the left, in the direction of swing.
  • To cut grass around flower beds, shrubs, and other objects, the grass trimmer head should be turned with the guard towards them. In this way, you can mow and not damage the objects themselves.

Remember, do not let the bobbin or disc touch the ground or any obstacle except grass and twigs to be mowed.

Mowing grass

Purpose of grass trimmer head (grass trimmer reel, mowing head, grass trimmer bobbin)

  • To remove all unwanted vegetation under walls, along fences, curbs, around trees, posts, bushes, between stumps and other obstacles.
  • To cut the grass in places not accessible for lawn mowers.
  • To selectively cut thinned grass and weeds before mowing the area for hay.
  • To cut weeds in the bed between the plants.
  • To shred potato foliage in the vegetable garden before digging it up.
  • To completely remove grass and weeds from, for example, paths.
  • To sweep up (creating an air vortex from the large revolutions of the grass trimmer’s line).

Note

The trimmer head (mowing head or grass trimmer reel) has a high output when cutting grass, t.к. it is lighter for the metal blade and has a larger working diameter of 45 cm, compared to 25 cm for the hay blade.

Tool varieties

Three versions of garden trimmers are available for sale. electric, battery and gasoline. The mains-powered models, plugged into the socket, are less common, as they have minimal opportunities for autonomous operation due to their connection to the power grid. In addition, in terms of economy, it is not the best grass trimmer for mowing the grass. Electric unit can justify itself only in the work around the house plots, if there is an opportunity to supply extension cords to connect the cable.

Potential for churning flying stones puts windows in houses and cars. Shields around the trimmer head are in place to reduce flying debris and protect the operator. no one removes the shields after the modified grass trimmer is no longer under warranty or can be used safely.

When refueling, make sure the engine is stopped and the grass trimmer is placed on a flat, level surface. preferably not grass. A grass trimmer should never stay on the grass for long periods of time. Re-fueling should be done with a proper system to avoid leaks or overfilling.

Gasoline models have always been considered a direct competitor to electric models. They offer high power, virtually no restrictions on movement, and can even cut through bushes. But, a gasoline grass trimmer for mowing grass is also characterized by high weight, noisy operation, strong vibrations, exhaust emissions and high cost. Cordless versions are not tied to a power source either, but they lose out to gasoline trimmers in terms of performance.

Be sure to use the appropriate string weight as indicated in the user manual. Grass trimmer string that is too thick for the motor can cause damage. Some grass trimmers can accept a trimming blade, but never use a blade on a trimmer that is not designed to use trimming blades. Accessories that are not designed for a particular grass trimmer can create excessive vibration, motor wear, or binding. This can lead to motor strain, possible component failure and potential damage to the operator.

Popular questions about gasoline garden trimmers

In this section we’ve answered a few common questions about gasoline trimmers.

Why the lawnmower does not start?

If you can not start the gasoline trimmer or it immediately stops, it is necessary to check the ignition by removing the spark plug. Dry spark plug means that the problem lies in the system responsible for the fuel supply. Wet spark plug indicates a faulty ignition system. If the spark plug is soiled, clean or replace it.

Another reason could be a clogged air filter. If it is dirty with oil, you need to clean, wash and dry it.

Why does the lawn trimmer stall??

When the throttle is depressed

  • If the gasoline grass trimmer stalls when you step on the gas, you need to check the air damper. If it is set in the closed position, it needs to be set in the open position.
  • Another option is a clogged filter.
  • The gasket between the cylinder and carburetor may also be damaged.
  • A cracked fuel hose will cause air suction.

At idle speed

It can happen that the lawnmower stops after a short time after starting. Causes may include:

  • Improperly adjusted carburetor;
  • contamination of the carburetor, filter or throttle valve;
  • Air in the carburetor system;
  • malfunction in ignition system;
  • Lack of gasoline.

Why does the lawnmower get hot??

  • One of the warmest parts is the gearbox. If there is not enough lubrication in the mechanism, the gears will experience friction and get hot. This can also happen with new gearboxes where the gears have not yet been lapped. Gearboxes can reach working temperatures of up to 60°C.
  • Using the lawnmower at maximum strain is another reason for overheating. The tool should rest regularly.
  • There may not be enough oil in the fuel mixture. this leads to oil starvation, increased friction, and a lot of heat generated during operation.
  • Clogged holes for cooling air flow.

The lawnmower. what to replace the line for the trimmer?

Choosing the right mowing head

In addition to its product, the manufacturer usually provides several cutters (usually 3).

  • To work with soft grass, a trimmer line wrapped around a drum is used as a cutting element. Speed of 9000 rpm allows you to quickly process even a large lawn.
  • For coarser grass and thickets you can use one of the metal blades, which have a different number of teeth.
  • For mowing dense weeds, reeds, young bushes the disk with 40 or 80 teeth is designed. Maize, dry weeds with thick stems can be mowed with a three- or four-blade burr.
  • To lay mowed grass in swaths a blade with 8 blades is used and a special comb is installed on the scythe itself.

And now more about how to mount the cutter. The gearbox is where the tiller is mounted. First of all, a shaped washer must be fixed on it with an Allen key.

Then place the blade, aligning the holes in it with the protrusion of the washer. After that, you need to install the top shaped washer on the shaft and screw everything with a nut.

it is necessary to pay attention that the thread on the shaft is left-handed, that’s why the nut (as well as the mowing head) has to be tightened counter-clockwise.

The key included in the delivery set will help you to tighten the nut up to the stop. If you want to change the cutter bar, you can do it in reverse order.

As we have already written, lawn mower with a fishing line can be automatic, semi-automatic and manual. In the first case, the cutting element “ejects” itself after each new start of the machine. This is very convenient, but not economical enough, for example, if your area is irregularly shaped and contains corners, jagged edges, and at a long transition to each of such areas the mechanism must be turned off and on again.

How to use the grass trimmer with a blade

Regardless of which blade you use, always keep it so that it is parallel to the ground. Adjust the straps so that the grass trimmer sits comfortably in this position, with part of the boom behind the handle resting on the shield on your hip.

Knives can only be used on a straight shaft trimmer. This means that the knife rotates counterclockwise. This means that it’s best to cut with the left side of the blade and move the grass trimmer head to the left.

If you cut with the right side of the knife (especially the right front side), you may experience a knife bounce (kickout) or as the Americans say. The bounce (kick) of the blade is a quick jerk or jump of the grass trimmer, as if it hits an obstacle and bounces. It can be unsafe.

Mowing different types of vegetation

In addition to keeping the knife parallel to the ground and cutting thicker thickets with the left side of the knife, there are a few tips to consider for each type of vegetation you may encounter:

Grass and weeds

To cut tufts of grass and weeds, make sweeping motions back and forth in long arcs, as if you were using a scythe. Hold the grass trimmer so that the blade barely hovers above the ground.

Dense shrubbery

Cutting thick, dense bushes starting at the base of the plant is not the easiest way. Instead, start by raising the blade to about waist level, keeping it parallel to the ground. Lower slowly until the blade is just above the ground. Never raise the knife above waist level.

gasoline, grass, trimmer

Small trees and saplings

Grass trimmers with saws can be used to cut trees up to 2.5 cm in diameter. For larger diameter trees, use a chainsaw.

Hold the grass trimmer so that the blade is 5-15 cm above the ground. Get in a stable position and press the left side of the blade against the right side of the tree. Cut evenly, without pushing.
