Small mechanization in modern agriculture is an indispensable thing for most processes. A do-it-yourself creeper for a walk-behind tractor makes it possible to optimize the work of cultivating and hilling a garden plot or farm plots. The lowering unit serves as a power converter of the units, saving the device's life and the cost of its operation.
Destination
A self-supporting creeper for a walk-behind tractor allows you to process โgreasyโ soil, virgin soil and other types of soil. At the same time, the depth of cultivation, transportation of goods, the possibility of operating attachments remains 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 as a whole. In this case, a simple creeper for a walk-behind tractor just helps. Do it yourself with your own hands is quite simple, having basic locksmith skills. These elements make it possible, without losing indicators of power and revolutions of the engine components, to obtain the required control over the process of cultivating the land. In some cases, the strength of the cultivator even increases. Having a certain experience and knowledge, it is easy for the user to convert the finished device or create it yourself.
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 construction mechanisms. In addition, the rules for servicing, operating and storing devices should be studied. The elements under consideration have both pros and cons.
A self-made creeper for a walk-behind tractor often consists of one or a couple of steps, depending on the number of gears. The advantages of the mechanisms include:
- reliability;
- long service life;
- small overall dimensions;
- the possibility of equipping mechanisms with reverse.
The disadvantages of the devices include poor maintainability and high cost. When a part fails, the whole item needs to be replaced, which is not so cheap. Adequate oil levels should also be monitored. Lack of lubrication leads to increased wear on the unit.
How to make a creeper on a walk-behind tractor with your own hands?
At the first stage of manufacturing the mechanism in question, it is necessary to determine the type of transmission, working number, center distance between the drive shafts and the wheels themselves.
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 work of the entire device. In addition, the mutual position of the axes among themselves and the correspondence of the bearing seats are taken into account. As a rule, the skeleton is made of sheet steel by welding. In this case, one of the walls is removable, which facilitates the maintenance of the mechanism.
- The system of a self-made creeper reducer for a motoblock includes a high-speed (incoming) shaft, a worm gear system or an analogue of asterisks.
- The number of teeth on drive wheels is always greater than on driven gears. Couplings, bearings, dowels and fasteners act as auxiliary parts.
For the independent construction of this device you will need such materials and tools:
- "Bulgarian";
- apparatus for welding;
- a drill or a screwdriver;
- appropriate drills and files;
- tape measure, vernier caliper;
- hammer;
- sheet metal 5 mm thick;
- pieces of pipe with a diameter suitable for inserting bearings into the inside.
Do-it-yourself reducer for the Neva motor-block do it yourself
On this unit, craftsmen put a device that combines a 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 adjusted by adding or removing links.
When designing a walk-behind tractor, developers do not always take into account the optimal location and interaction of all associated units. Often, the introduction of intermediate parts into the design, such as a transmission element, is required. Such an option is quite capable of chain transmission, which compensates for the distance during the transformation of traction from gears or a โwormโ 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 is fixed by spot welding. At the next stage, the method of fastening the driven shaft and a pair of half axes is chosen.
During installation, it is necessary to take into account the possibility of displacement of the star in one of two directions. The body part is made independently or with the help of specialists. If the first option is selected, consider the features of the gaskets, the corresponding seals and bearings.
Worm gear
Here the main element is the transmission of the worm type. In this case, it is possible to reduce the dimensions of the cultivator and increase the weight distribution. The latter is improved due to the perpendicular placement of the drive wheels and shafts.
What are the benefits of a worm gear?
- A large gear ratio.
- Small dimensions.
- Light weight.
The disadvantages of the worm assembly include the lack of reverse and the need for a complete replacement of the element when its main parts fail.
Features
Small mechanization in agriculture is very popular. Motoblocks and cultivators are often purchased for private households. They allow you to perform all the work on processing fields without significant costs for maintenance and operation of equipment.
In combination with appropriate attachments, walk-behind tractors will be the best option for soil treatment. The demand for these machines is due to the fact that they promptly and economically fulfill their tasks, in contrast to bulky and obsolete combines and tractors.
In conclusion
In a logical decision to reduce the speed of the power unit at the level of maximum speed and performance, creeper reducers of cultivators and agricultural units are focused on lowering the used power. At the same time, the overall working capabilities are preserved, and the process does not stop and does not slow down.
