How to reduce the speed of the walk-behind tractor using pulleys

How to reverse speed on a walk-behind tractor

Consider how to make a reverse speed on a walk-behind tractor. The presence of a reverse depends on the model and dimensions of the mini-equipment. You can cultivate the land with a motor cultivator, a light walk-behind tractor and a heavy machine. It all depends on the goals and objectives set. Usually, when using models weighing up to 30 kg, there is no need for a reverse speed, moreover, it complicates the design of the unit. On a heavy machine without this function, it will be more difficult to do the job.

Agricultural machinery will not move without a gearbox. It happens:

The task of the bevel gear is to ensure the collision of the transmission with the engine, which affects the power of the gear. The gear is the transmitter between the motor and the wheels. The reduction gear serves to reduce the speed to increase power.

The reverse gear has a clutch located between the gears. They are on the main roller. The main task of this system is to ensure the reverse gear of the equipment. To make this mechanism yourself, the first thing you need to do is prepare a case, for which many use a two-inch fitting square.

You can use the generator shaft from the Ural motorcycle. The gears will fit from the Friendship chainsaw. In the shaft, you just need to drill a hole of the appropriate diameter. Mount another pinion shaft with bearings on the opposite side. And already on the weekend, fit a pulley to ensure rotation.

You can purchase a ready-made gearbox, only when buying it is better to give preference to more expensive mechanisms, since they are more reliable and last longer.

Among the malfunctions of gearboxes, users highlight the rapid wear of the gears and the fact that the transmission takes off.

If you increase the speed of the cultivator, then you need to take into account that wear will occur much faster. When doing land work, I want to quickly cope with the task. To increase or decrease the speed of movement, you can try the throttle stick. If the work is hard, then when the gas decreases, the engine will stall.

The first speed is used when plowing the land when more power is required from the machine. Faster work reduces the depth of cultivation.

How to adjust the speed?

Sometimes it turns out that you want to change the speed of movement of your motoblock device: increase or, which happens quite rarely, decrease it.

To increase the speed of movement of motoblock units, one of the following two methods is usually used:

• replacement of wheels with large ones;
• replacement of a pair of gears of a reducer.

The usual wheel diameter of almost all motoblocks is 570 mm. Most often, when replacing, tires are selected with a diameter that is approximately 1.25 times larger than this. 704 mm. Although the difference in size is relatively small (only 13.4 cm), the speed of movement increases significantly. Of course, if the design allows for larger tires, you can try to increase the speed gain.

The gear pair installed in the wheel reducer usually consists of two gears with 12 teeth for a small one and 61 for a large one. You can change this indicator by 18 and 55, respectively (only for specialists in agricultural machinery service centers), then the speed gain will be approximately 1.7 times. Do not try to carry out the operation of replacing the gears yourself: it is very important here to select not only high-quality parts with minimal errors, but also the appropriate pulley. The gearbox shaft retaining plate also plays an important role.

Logically reasoning, reducing the speed of movement of the walk-behind tractor can be achieved by performing diametrically opposite actions. to reduce the diameter of the tires or the number of teeth on the gear pair.

A possible solution to increasing the speed is to adjust the throttle switch: when the machine is turned on, move it from the first position to the second. To reduce the speed of movement, return to the starting position. Of course, to change the speed downward, you do not need special reducers. it is enough not to switch to high gears.

Also possible solutions to the problem of increasing the speed of the walk-behind tractor are replacing the motor with a more powerful one and upgrading or installing a clutch system (in some outdated models it is not provided).

It can help to increase the speed (especially on uneven terrain or heavy soils, where slippage of the equipment is frequent due to insufficient weight of the unit) and the installation of weights. They can be made with your own hands from metal parts. Weighting structures are installed on the walk-behind tractor frame and wheels. For the frame, you will need metal corners, from which a self-made removable structure is formed, that is, you can easily remove it if not needed. Additional ballast weights are attached to this removable additional frame. The wheels need discs made of steel and solid iron blanks with a cross-section in the form of a hexagon. These parts are welded and inserted into the hubs. For reliable fixation, cotter pins are used, which are installed in specially prepared holes.

Of course, if there are no round steel elements at hand, you can replace them with almost any material at hand: reinforced concrete products or even flattened round plastic flasks, inside which sand is poured.

Do not forget about maintaining balance: the weights on the wheels must be equal in mass, and evenly distributed over the frame, otherwise there will be a skew, due to which, when performing turning maneuvers, your unit may fall to one side.

To speed up the walk-behind tractor with a trolley in bad weather conditions. snow, slush, soil sour from torrential rains. you can put tracks (if the design allows). This method requires the installation of an additional wheelset and the purchase of rubber tracks of a rather large width. On the inner side of the track, restraints are attached to securely fix the rubber and prevent it from jumping off the wheel pair.

Also for this purpose, you can replace the native gearbox with a similar device with a low gear. to facilitate overcoming obstacles.

And do not forget about prevention: change the oil more often, regularly lubricate all the components of your mechanical friend, monitor the condition of the candles, replace worn parts with new ones.

If you take good care of the unit, follow all the recommendations for operating the device, carry out regular preventive maintenance, then the walk-behind tractor will give out its maximum capabilities in terms of speed and performance.

DIY creeper for walk-behind tractor

Auto mechanic specializing in agricultural machinery

The time has passed when it was necessary to spend almost the whole day on cultivating a small plot of land and work for wear and tear. Well, whoever had a walk-behind tractor. everyone in the neighborhood envied such an owner. This is not the case now. The motorized agricultural mini-machinery occupies a leading position in terms of the number of sales. Additional equipment used in walk-behind tractors and the power of a mini-tractor allow you to successfully process large areas of personal plots. Extra strength is required when working on heavy soils. For this, a reduction gear or the so-called creeper for a walk-behind tractor is widely used.

They are installed together with pneumatic wheels and are practically not used on a wheelset with grousers. Reducing the speed and speed of the walk-behind tractor allows you to increase the tractive effort of the unit. It will not be difficult to make it yourself.

Ways to increase speed on a walk-behind tractor

Many farmers are interested in how to increase the speed of the walk-behind tractor. The most common agricultural technique is the walk-behind tractor. With its help, the performance of work on land and personal plots is greatly simplified. Let’s consider how you can increase the speed on this technique. With the increased speed, the productivity and cross-country ability of the mini-car will increase, which can be used in any season and weather.

Drawing

When planning the execution of work, you should always remember the importance of drawing up diagrams and drawings. It is advisable that they be done professionally. The drawing contains all the data for the manufacture of the model and its operation: the required torque, the number of shaft revolutions. He accurately explains the principle of interaction of structural parts.

How to increase the speed of the walk-behind tractor

There are two ways to increase the speed of the walk-behind tractor:

• installation of large wheels;
• replacement of a gear pair.

Let us first consider how changing the wheels helps to increase the speed of the cultivator. The standard wheel size of almost all mini-unit models is 57 cm. When changing, tires that are 1.2 times larger in diameter can be installed. Usually, wheels of 70.4 cm are used. Despite the small difference, the speed of the walk-behind tractor increases noticeably. If the arches into which the tires are inserted will allow you to insert wheels with a large diameter, then you can try adding centimeters.

Let’s consider how to increase the speed on a walk-behind tractor in the second way. Like any technique, the cultivator has several speeds, which are controlled by gears. Usually cultivators move at a speed of 2 to 15 km / h, while the large gear has 61 teeth, and the small gear has 12. To increase the speed, the gear pairs of the reducer are replaced. We increase the number of teeth, thus the maximum speed of the walk-behind tractor is achieved.

It is recommended that the replacement be carried out by professionals and preferably in specialized centers, since parts turned with a minimum error will affect the operation of the motor. It is not only the replacement of the gear that is important, but also the correct selection of the pulley.

What are the minimum and maximum speeds of the walk-behind tractor and how to adjust them?

Today, walk-behind tractors are perhaps the most common type of mini-equipment for agricultural purposes. It so happens that users of some models no longer satisfy the speed and performance of the unit. Buying a new model is quite expensive. In this case, you can try to upgrade your device.

A walk-behind tractor is a kind of mini-tractor, sharpened for a variety of agricultural operations on relatively small areas of soil.

Its purpose is to carry out arable work on small and medium-sized land plots, till the land using a harrow, cultivator, cutter. Also, motoblock devices can process planting of potatoes and beets, mow grass, transport goods (when using a trailer).

It is also possible to use additional attachments to expand the list of tasks performed by this powerful, in many cases indispensable unit: a trolley trailer for transporting goods weighing up to half a ton, cutters, harrows, etc.

There are gasoline and diesel varieties of motoblock devices. For the most part, diesel units are more powerful than their gasoline counterparts. In the price category, gasoline-powered devices win. they are cheaper. But the choice largely depends on the size of the land allotment and the frequency of use of this technique, because diesel fuel is more affordable than gasoline.

Motoblock devices come in two- and four-wheel configurations. Not all devices have a reverse-reverse function.

Fastest models

First, let’s find out which walk-behind tractors are considered the fastest? Do domestic manufacturers have advantages or the palm belongs to foreign competitors unconditionally??

By the way, it is quite difficult to determine the unconditional winner in terms of maximum speed, because not only are there simply a great many models of walk-behind tractors from different manufacturers, and independent modernization of this multifunctional agricultural unit is possible.

The number and speed indicators of the walk-behind tractor depend on the engine and gearbox installed in the unit.

The MTZ-05, MTZ-12 walk-behind tractors have 4 speeds when moving forward and 2. backward. The minimum speeds correspond to the first gear, when shifting to the next speed it increases. For the aforementioned models, the minimum forward speed is 2.15 km / h, while the reverse is 2.5 km / h; the maximum in the forward course. 9.6 km / h, with the rear. 4.46 km / h.

The “Mobile-K G85 D CH395” / Grillo walk-behind tractor has a maximum forward speed of 11 km / h, reverse. 3 km / h. At the same time, the gearbox provides the ability to switch between three forward and two reverse speeds. Don’t forget that all of these metrics are true for unimproved models.

“Mobile-K Ghepard CH395”. a Russian-made walk-behind tractor, has a 41 gearbox, can accelerate to 12 km / h.

Ukrainian motor-block “Motor Sich MB-6D” can reach a speed of 16 km / h, six-speed gearbox (42).

The unit “Centaur MB 1081D” is Russian, but produced at Chinese factories. It is considered the fastest walk-behind tractor in the heavy class. The maximum speed of its movement is as much as 25 km / h! Refers to diesel motoblocks, unlike the models listed above. they run on gasoline.

How to reduce the speed of the walk-behind tractor

To solve certain problems (plowing virgin lands and heavy soils), some models of walk-behind tractors may be too high-speed, in which case it is necessary to reduce the speed.

To reduce the speed, you can reduce the diameter of the wheels or replace the gear pair in the wheel reducer by changing the gears. Gears of different sizes are usually installed, with the number of teeth of 61 and 12, in order to reduce the speed, it is necessary to replace them so that the number of teeth on the larger sprocket increases.

Maximum speed of the walk-behind tractor

Many owners are wondering: what is the fastest speed possible on a walk-behind tractor? The answer depends on many nuances, mainly on the model of the walk-behind tractor. It is also important to take into account that the working speed is lower (2-4 km / h) than the speed of the walk-behind tractor when transporting goods. If the working speed is increased, some types of work will be more difficult to perform, since the control of the walk-behind tractor will become very difficult for the operator. If the walk-behind tractor is used as a vehicle, then its speed can reach 30 km / h.

How to increase the speed of the walk-behind tractor

There are two ways to increase the speed of the walk-behind tractor:

The best models of high-speed motoblocks

A fast walk-behind tractor is an irreplaceable assistant when transporting goods in rural areas or when working over a large area. Diesel walk-behind tractor Centaur MB 1081D is the fastest among heavy-class walk-behind tractors, can reach speeds of up to 25 km / h. Motoblock Motor Sich MB-6D has a maximum speed of 16 km / h.

Popular models of motoblocks from domestic manufacturers have a much lower maximum speed. on average, 12 km / h for MB-2 and MB-23, Neva. Also, the Mobil-K Cheetah walk-behind tractor has a good speed. 12 km / h (gearbox 41).

With the increased speed, the productivity and cross-country ability of the mini-car will increase, which can be used in any season and weather.

What is the speed of the walk-behind tractor

The speed of the walk-behind tractor depends on several parameters:

• walk-behind tractor class
• engine type
• availability of attachments
• type of gearbox
• wheel size
• the area where the walk-behind tractor works

As a rule, the class of the walk-behind tractor is associated with the type of engine, light models are equipped with gasoline engines with a capacity of up to 5 HP, medium ones. with gasoline engines of 6-12 HP, heavy ones. with diesel engines with a capacity of 12 HP or more. Diesel engines are more powerful, so equipment with such engines will have a higher speed.

Among the budget models of middle-class motoblocks, the type of gearbox is common 2 forward, 1 back, more expensive models have 6 forward and 3 reverse gears. The more gears, the higher the speed is available.

Wheel size matters: the larger the wheel diameter, the faster the equipment moves.

Attachments such as plows, mowers can reduce speed. The speed will be lower for a walk-behind tractor with a trailer, although it is possible to accurately calculate the speed with a trolley only when taking into account the speed and weight of the walk-behind tractor itself, as well as the weight and type of cart. Usually the speed of a walk-behind tractor with a trailer does not exceed 10 km / h.

The more difficult the terrain, the more the speed decreases. For plowing on virgin soil, it is recommended to use weighting materials that ensure passability and help maintain speed. However, it is worth remembering that plowing heavy land at high speed is not recommended, as the quality of land cultivation decreases.

Do-it-yourself speed increase

How to make your walk-behind tractor faster? It should be noted that we are talking about transport speed. Motoblock Neva MB-2, with certain modifications, can reach speeds of more than 20 km / h, however, if it does not have a differential, then control becomes much more complicated.

You can increase the speed in several ways, for example, put wheels of a larger diameter or change the gear pair of the wheel reducer, replacing the standard gears with 61 and 12 teeth 55 and 18, respectively. This method is quite difficult to implement, but it allows you to increase the initial speed by almost 2 times.

Some owners want the walk-behind tractor to drive at 40 km / h. It is possible to make such a modification, but it must be borne in mind that there will be a large load on the gearbox, and it will be difficult to drive such a vehicle.
