What an Attachable Tool Kit Can Do

The universal nature of the walk-behind tractor design means that additional working tools and equipment are used exclusively as attachments for the walk-behind tractor. During operation, it can be easily removed and replaced, without interfering with the design of the walk-behind tractor.

The vast majority of attachments for walk-behind tractors are developed and produced primarily for cultivating soil and growing vegetable and grain crops in small areas of personal plots. Therefore, all attachments can be classified into three categories:

• Equipment for plowing, cultivating, milling, cutting furrows, drawing and harrowing soil. To work with soil preparation, the largest number of attachments and attachments are produced, both by manufacturers of walk-behind tractors and by companies that sell agricultural tools;

  

• Additional mechanization used for fine work with planting seeds and harvesting, these also include motor cultivators, mowers and other equipment for working in beds;

• Auxiliary attachments and attachments. Oddly enough, auxiliary work, transport operations and use as a snow blower account for almost half of the operating hours of a walk-behind tractor with attached equipment.

  

Important! Due to the high degree of unification of the design of the main unit with the motor, owners of different models of walk-behind tractors can partially adapt attachments and attachments for “foreign” models to their units. Especially when it comes to “Soviet” models.

• The small and maximum throttle arrow is twisted to the end, then turned back 1.5 turns;
• Warm up the engine (at least 5 minutes);
• Start the engine and run it at the lowest speed;
• Set the throttle screw to such a low idle speed that the engine will run optimally, smoothly and quietly;
• Using a small gas needle, the idle speed is adjusted to maximum;
• Set the minimum idle speed screw. Repeat the previous and this paragraph of the algorithm until the engine starts working properly;
• Move the engine control lever to the “gas” position;
• Adjust the maximum throttle until the engine returns to normal when there is noise or interruption.

For clarity, we recommend that you familiarize yourself with the video of the carburetor model K45-M3 on the Belarus MTZ 12 walk-behind tractor:

When adjusting the carburetor, remember the main thing. Each walk-behind tractor model has its own optimal settings! And they are all listed in the manufacturer's instructions. If you have even the slightest doubt as to whether you can do everything correctly and adjust the carburetor, it is best to immediately contact a specialist.

Typical attachment options for walk-behind tractors

Manufacturers of equipment for walk-behind tractors have divided the entire range of attachments into two groups:

• Complex devices with power take-off from the power unit to drive working tools. Such equipment options cost a lot, but are in high demand among walk-behind tractor owners. This is, first of all, equipment for planting seeds and harvesting crops;

  

• Simple attachments and additional accessories, most of them are sold complete with the walk-behind tractor or are available for an additional fee. Extensions, lugs, towbars, they are inexpensive, but without them the efficiency of the unit is noticeably reduced.

The simplest attachments and attachments for a walk-behind tractor

Such devices include a number of plows, milling cutters, and hillers for universal purposes.

Most of them are single-row, but for heavy models of walk-behind tractors, multi-row ones can also be used, most often these are cutters and cultivators.

For each walk-behind tractor model, the manufacturer produces a whole range of extensions and attachments that can increase the wheelbase and increase the stability of hitches for installing a plow or knife hiller. In some cases, using hitches, you can attach small harrows or rakes to the walk-behind tractor, the use of which can significantly increase the efficiency of working with mown plants and their remains in the ground.

A mandatory tool is lugs installed on walk-behind tractors for heavy work - plowing or milling the soil. To work on particularly difficult areas, you can use additional reinforced lugs with hanging loads.

The second most popular after the plow are cutters for cultivating land. Usually they use double ones, but if desired, you can supply tools with an increased number of knives.

Types and purpose of attachments

Small private farms and farmers are used to saving in everything. The walk-behind tractor is used in a variety of ways; it mechanizes all types of work. An engine running on gasoline or diesel fuel with sufficient power allows you to solve a wide range of problems.

The purpose of walk-behind tractors is, first of all, soil cultivation. The devices make it possible to plow, hill, plant crops, and harvest a rich harvest. The units will perform the job properly on a small area of ​​up to 4 hectares. Attachments significantly expand the range of tasks performed. The devices are capable of:

• remove snow;
• dig a ditch;
• mow the lawn;
• mow the grass.

The list is incomplete; the possible number of works is significantly greater than those listed. Various mechanisms can use a walk-behind tractor that serves as a drive. A wide range of issues solved by additional equipment makes the unit invaluable and allows you to perform many agricultural, construction, and household work.

The functions and capabilities of the walk-behind tractor place it between a mini-tractor and a motor-cultivator. The device is more versatile than a motor cultivator. The device performs work by applying traction force. The cultivator solves only narrow specialized cultivation tasks. The device loosens the soil surface.

The walk-behind tractor has a single axle, it does not have a seat, and the operator holds the device with his hands while walking behind. It is possible to equip the device with a trailer. This option requires a seat. Extra heavy models are equipped with a third wheel and a seat. These options have significant similarities with a mini-tractor.

Important! The walk-behind tractor differs little from the tractor structurally; it has the same parts.

Often the concepts of a walk-behind tractor and a cultivator are equated, but they do not see much difference between them. The two devices, meanwhile, have fundamental differences regarding the functionality of the devices.

Tillage occurs using both types of equipment. The devices prepare the soil, improve the soil structure, and mix soil and fertilizers. The main element of both units are cutters that are immersed in the ground, allowing for plowing with a minimum of effort. On a small plot of several hundred square meters, it is worth using a lightweight model. Such devices can be electric, gasoline, or diesel.

In addition to cultivating the soil, the walk-behind tractor easily performs other work. Using the appropriate attachment for a walk-behind tractor will allow you to mow grass, harvest potatoes, and other root crops. Even harvesting is easy. The walk-behind tractor has rich functionality and is much superior to a cultivator. The product market offers tempting options. You can purchase a model equipped with headlights that can operate at night. An interesting option is equipped with knives that allow you to dig ditches. Additional attachments make the equipment more expensive.

The functionality of the walk-behind tractor is very great. The device will help you perform many types of work. The device uses a wide range of attachments. It is very useful to attach a powerful pump, a trolley is useful. Some models are equipped with a plane and a circular saw. The low power of the unit does not affect the performance or speed of operations.

A private farm or farmer purchases one or another unit depending on the type of work performed. Plowing virgin soil and cultivating row spacing require different techniques. More powerful models cost much more. You need to spend money efficiently; the performance of the device must match the type of work. The areas are classified as follows:

1. An ultra-small plot is considered to be less than 10 acres, which involves different zones - garden, flower beds, beds, lawn.
2. A plot of up to 40 acres is considered small. It is divided into several zones.
3. The average plot of 50-90 acres is used for a couple of crops.
4. A large plot - more than 100 acres - requires too many types of work. The cultivator will not be able to do everything.

For owners of large plots, it makes sense to use heavy models equipped with attachments.

Important! The heavy model does not weed.

An addition will be an ultra-light model that allows you to perform weeding. The owner of a small plot should think about how to purchase a medium-sized unit that makes it possible to cultivate the soil in an optimal way.

Attachments for salute walk-behind tractor

Currently, in the list of additional devices for walk-behind tractors, the most popular are relatively new models - seeders, potato planters, harvesting devices and snow removal tools. Nozzles and mechanized units for planting seeds allow sowing to be carried out at the most optimal time, when the deadline is days or even hours.

For example, additional devices for sowing small seeds and grain crops. The design of the attachment is very similar to that used for full tractor-mounted seed drills.

Potato planters KS-1, with a weight of just over 40 kg, allow approximately 100-120 kg of seed potatoes to be planted in a prepared furrow in an hour to an hour and a half. The seed is loaded into the hopper and driven by the planter's chain drive to be placed into the soil at precisely measured intervals. It is clear that before operating the attachment, it is necessary to cultivate and cut furrows in the ground.

No less interesting is the equipment for digging and harvesting potatoes. You can simply dig the tubers out of the ground with a special type of plow, but it is better to use a more universal version of attachments that help even partially harvest the crop.

It is worth mentioning a separate category of attachments used for mowing green mass. For example, a rotary mower for Salyut with a chain drive of the cutting tool allows you to mow the grass many times faster than when using a self-propelled lawn mower. The hinged design of the GPM-1 rake allows you to remove mown hay without much effort.

A disc hiller or flat cutter is perfect for hilling and cultivating row spacing.

In addition to cultivating the land and harvesting crops, you can use special attachments for Salyut, designed for watering and spraying shrubs and trees. This is a water pump capable of creating pressure up to 5 atm.

Snow removal attachments

Experience working with walk-behind tractors has shown that, when properly equipped with attachments, a walk-behind tractor works perfectly as a snow blower. One of the most successful options for a mounted snow blower is the SMB-1 mounted kit.

Using a rotary blade and ejector, the snow blower is capable of removing compacted snow up to 200 mm thick from the road surface, and the entire mass of snow is thrown to the side of the road at a distance of up to five meters. An alternative to using such equipment may be using a tractor or working with a shovel.

To clear wet snow, you can use a mounted plow blade. A blade one meter wide makes it possible to lift and remove heavy snow saturated with water and ice up to 30 cm thick. At the same time, the installed equipment includes an additional handle that allows you to change the direction of the cut. If you wish and have a sufficiently powerful engine, you can even cut off the top part of the turf on sandy soil with a walk-behind tractor. Essentially, a blade shovel and adapter can turn a walk-behind tractor into a miniature bulldozer

The final final sweeping of the canvas can be done using a snow blower based on a rotary broom. This attachment will not only remove dirt and stone from the road surface, but is also capable of removing ice and compressed frozen snow up to 10 mm thick.

Motoblock carburetor design

To properly adjust or clean the carburetor on a walk-behind tractor, you must first say a few words about its design.

READ Screwdriver For Husqvarna Carburetor Adjustment

It is known that the carburetor in a walk-behind tractor is a certain part of the fuel system and performs the function of atomizing fuel enriched to the required extent with oxygen. Most modern walk-behind tractors run on gasoline engines (although there are alternatives: diesel and electric). Their designs are mainly of two types: rotating (simple in design and designed for less powerful engines) and piston (for more powerful walk-behind tractors, multi-element).

Externally, a carburetor for a walk-behind tractor looks like this:

The internal structure of the carburetor of the K 45 type walk-behind tractor, which runs on gasoline, looks schematically like this:

Transport attachments

A walk-behind tractor with a sufficiently strong motor can be easily converted into a small cargo vehicle capable of carrying from 100 to 400 kg of cargo. This will require a special type of hitch and a single axle trailer.

The average speed on rough terrain is up to 10 km/h, on the road you can move up to 15-18 km/h. Most of the inconveniences associated with the use of such equipment are due to the fact that the transmission gear ratios do not combine well with the optimal speed and speed of the walk-behind tractor. Considering the lack of full-fledged control and braking controls on the walk-behind tractor, in order to control the unit on a hitch with an overloaded trailer, quite serious experience and skill in driving such motor-units is required.

If desired, using an additional attachment adapter, you can turn the walk-behind tractor into a microtractor that is quite maneuverable and powerful. By adding grass cutting equipment to it, you can get a full-fledged motorized lawn mower.

Many interesting examples of attachments for walk-behind tractors were created by enthusiasts, for example, a tracked transporter. Or a system for spraying and chemical plant protection. Most of these models are subsequently copied quite successfully and used to develop industrial equipment designs.

Adjusting the walk-behind tractor carburetor

Instability of the cylinder block indicates the need for carburetor adjustment. The need to perform this procedure usually arises before the start of the growing season, when the equipment has not been used for a long time, or after it, when the cultivator has been subjected to significant loads for a long time. The engine must be warmed up before making adjustments. The actual workflow looks like this:

• The screws that adjust low and high throttle are fully tightened and then backed out about one and a half turns.
• The engine is started by the starter or manually and warms up for about 10 minutes.
• The lever controlling the power unit must be set to the minimum position, but the engine must not stop.
• The throttle valve adjusting screw will help you adjust the minimum idle speed so that the operation of the diesel engine is stable, without any extraneous noise or stalling.
• The rotation of the screws allows you to accurately determine the amount of combustible mixture entering the engine.
• Tightening the propeller helps enrich the mixture, and unscrewing it, on the contrary, increases the volume of air entering the engine;

Use the idle screw to adjust the maximum idle speed. The same should be done at minimum speed using the screw locking screw. The essence of this adjustment is that the valve screw allows you to adjust the angle at which it is closed;

The lever responsible for controlling the engine must be moved to the “gas” position. If the operation of the cultivator is still not stable, then the screw with full throttle is adjusted to achieve the ideal stroke. However, the maximum permissible propeller speed is 2.5.

The accuracy of carburetor adjustment can also be determined by how the spark plug looks after a short period of operation under load. If the working mixture is ideal, the spark plug will not leave soot or traces of fuel, which indicate that the fuel mixture is too lean or, conversely, too rich. It should be noted, however, that soot or traces of fuel on the spark plug may indicate not only incorrect adjustment, but also more serious problems with the Chinese or domestic walk-behind tractor, including a faulty ignition or cooling system.

Adjusting the care of track valves

Over time, under high loads, the valve clearance of the engine cylinder block changes. The reason for this may be wear and tear of parts. Insufficient distance leads to the fact that the gas distribution stages change significantly, as a result of which it is impossible to achieve a sufficient compression ratio, the power device operates intermittently and does not achieve the declared power. In particularly severe situations, even valve deformation is observed. If the gap is too large, significant mechanical noise is recorded, valve timing also changes significantly, valves open for too short a time, causing the cylinder to not fill properly, power loss and failures occur. Adjustment of the gap is necessary immediately as soon as the engine fails or produces significant noise. Ideally, an adjustable motor should be cool.

So, first you need to get to the flywheel. It is on this part that the upper dead center value is marked. The flywheel is hidden under a cover, so it needs to be removed. Before removing the cover, remove the air filter oil bath. To make it easier when removing the cover, you can secure all the latches with rubber bands. The wrench unscrews all bolted connections, after which the cover can be removed without problems.

On the flywheel you can see marks indicating TDC, as well as the values ​​of 5, 10 and 20 degrees. The 20 degree mark indicates the injection of a combustible mixture. The flywheel should be brought to top dead center, guided by the relevant section. The valve cover is unscrewed and removed.

The following tools should be used during the setup process:

• Screwdriver;
• 10mm wrench;
• Blade 0.1 mm thick.

According to the technical data sheet, the engine valve clearance of the cylinder block is from 0.1 to 0.15 millimeters, and therefore can be adjusted very precisely using a shovel. However, it should be noted that some blades are 0.8mm thick, which is unacceptable. The exact value can be found using a micrometer or from the information on the manufacturer's website. The regulation is as follows:

• Screwdriver;
• Loosen the nut, insert the blade and begin tightening;
• You should focus on the blade while carefully tightening the nut;
• The adjustment is carried out until the free play of the valve is eliminated. It should fit fairly snug.
• Reassemble the casing in reverse order, placing your hands in the oil bath in place.
