Small mechanization in modern agriculture is an indispensable thing for most processes. A self-made creeper for a walk-behind tractor makes it possible to optimize the work of cultivating and hilling a personal plot or farm plots. The step-down unit serves as a power converter for the units, saving the resource of the device and the cost of its operation.
Purpose
A do-it-yourself creeper for a walk-behind tractor allows you to process "fat" soil, virgin soil and other types of soil. At the same time, the depth of loosening, transportation of goods, and the possibility of using attachments remain at the proper level.
With a decrease in engine speed and a decrease in speed, the power of the unit is lost, which to some extent slows down the work process inin general. In this case, a simple creeper for a walk-behind tractor just helps. It is quite simple to make it with your own hands, having elementary locksmith skills. These elements make it possible, without losing the indicators of power and turnover of the engine components, to obtain the required control over the process of tillage. In some cases, the strength of the cultivator even increases. Having a certain experience and knowledge, it is easy for the user to re-equip the finished device or create it on his own.
Device and maintenance
To make a creeper for a walk-behind tractor with your own hands, you need to understand the location and principle of operation of the structural mechanisms. In addition, you should study the rules for the maintenance, operation and storage of devices. The elements under consideration have both pluses and minuses.
A do-it-yourself creeper for a walk-behind tractor often consists of one or a pair of steps, depending on the number of gears. The advantages of mechanisms include:
- reliability;
- long service life;
- small overall dimensions;
- possibility of equipping mechanisms with reverse.
The disadvantages of devices include poor maintainability and high cost. In case of failure, the part requires replacement as a whole, which is not so cheap. You should also check the sufficient oil level. Lack of lubrication leads to increased wear of the unit.
How to make a creeper for a walk-behind tractor with your own hands?
On the groundAt the stage of manufacturing the mechanism in question, it is necessary to determine the type of transmission, the working number, the center distance between the drive shafts and the wheels themselves.
A do-it-yourself chain creeper for a walk-behind tractor can be made according to the following scheme:
- The main part is the body. He is responsible for the quality of the entire device. In addition, the mutual position of the axles between themselves and the correspondence of the bearing seats are taken into account. As a rule, the frame is made of sheet steel by welding. At the same time, one of the walls is made removable, which facilitates the maintenance of the mechanism.
- The system of a do-it-yourself creeper for a walk-behind tractor includes a high-speed (incoming) shaft, a worm gear system or an analogue of sprockets.
- On the drive wheels, the number of teeth is always greater than on the driven gears. Couplings, bearings, keys and fasteners act as auxiliary parts.
For the self-construction of the specified device, the following materials and tools will be required:
- "Bulgarian";
- welding machine;
- drill or screwdriver;
- corresponding drills and needle files;
- tape measure, caliper;
- hammer;
- sheet metal 5 mm thick;
- pieces of pipes with a diameter suitable for inserting bearings into the inner part.

On this unit, craftsmen put a device thatcombines gear, chain and worm gear. This feature is due to the fact that the distance between the clutch axes depends on the working module and the number of teeth. In a chain drive, the distance is corrected by adding or subtracting links.
When designing a walk-behind tractor, developers do not always take into account the optimal location and interaction of all associated units. Often, intermediate parts, such as a transmission element, are required to be introduced into the design. Such an option is quite within the power of a chain drive, which compensates for the distance during the transformation of traction from gears or a “worm” to a wheel shaft.
Recommendations
First of all, the stars of the input shaft are mounted. If the structure is massive, the flange or keyway fastening is fixed by spot welding. At the next stage, the method of fastening the driven shaft and a pair of half axles is chosen.
When installing, consider the possibility of shifting the star in one of two directions. The body part is made independently or with the help of specialists. If the first option is chosen, consider the features of oil seals, related seals and bearings.
Worm gear
Here, the main element is the worm gear. In this case, it is possible to reduce the dimensions of the cultivator and increase the weight distribution. The latter figure is improved due to the perpendicular placement of the drive wheels and shafts.
What are the advantages of the wormgearbox?
- Large gear ratio.
- Small size.
- Light weight.
The disadvantages of the worm assembly include the lack of reverse and the need to completely replace the element when its main parts fail.
Features
Small mechanization in agriculture is very popular. Motoblocks and cultivators are more often purchased for private households. They allow you to do all the work on the processing of fields without significant costs for the maintenance and operation of the equipment.
In combination with the appropriate attachments, walk-behind tractors will be the best option for soil cultivation. The demand for these machines is due to the fact that they quickly and economically perform the tasks, unlike bulky and outdated combines and tractors.
Finally
In a logical decision to reduce the speed of the power unit at the level of maximum speed and productivity, the creepers of motor cultivators and agricultural units are focused on reducing the power used. At the same time, the overall working capabilities are preserved, and the process is not stalled or slowed down.
