When plowing or tillage in the garden is easier to use a walk-behind tractor with mounted equipment. This is due to the fact that lands in the garden, usually small; in addition, not all beds need to plow. In such circumstances, traktorist difficult to maneuver and how easy is unfolding almost on the spot. E. Kulikov (der. Bornukovo, Nizhny Novgorod region) when doing the tillers, on the basis of these considerations.
As the power unit chosen was the well-known engine with forced air cooling Т200М scooter “Tula Tourist”. Unlike regular complete installed on it TO carb-28G, air filter ZID-4.5 and a homemade silencer. The torque from the motor to the wheels is transmitted by a chain transmission which includes the gear from the chopper feed “Volgar”. The use of such gear, in addition to improving traction characteristics, provided the cultivator an opportunity of movement and reverse, which increased its maneuverability. Reverse is activated by turning lever reverse shaft associated with a corresponding leash reducer. This shaft runs in three bearings mounted on the bracket of the steering brace and the frame. Each leg is equipped with a bronze (brass) bushing.
Speed switch lever, submitted to the steering strut and the United rockers and rods with the axis of the gear shift motor. The rocking sleeve mounted on the axle, welded to the strut to the steering wheel have an inner groove for gasket grease in them. In fact, the main focus wheel engine controls: clutch lever, lever throttle, and an electric switch.
The motor assemblies, the gear, the intermediate shaft and the support axle is mounted on the frame, welded from steel pipes of rectangular section, thick-walled angles and strips. The majority of frame parts in the manufacture of pre-connected together by bolts, and after trimming and the final Assembly has failed. Intermediate shaft and axle drive axle rotates in the bearings used in agricultural machinery. The tension of the first and last circuits is adjusted by changing the position of these supports, and secondary — special tensioner with a sprocket mounted on a bracket on the left side of the frame.
In the rear of the frame to the steering brace welded to the headstock of agricultural implements. Because it is one of the most loaded elements of frame construction, it had to strengthen the steel gussets and a thrust bearing. The bracket is made in the form of an inverted U-shaped profile (rectangular tube profile with cut upper wall).

The design of the plough has three swivel joints, allowing you to adjust the angle of the blade and during the maneuvers to throw it aside a u-turn around the horizontal axis. Required amount of penetration of the ploughshare into the soil by the farmer is aged using the steering wheel. To facilitate these steps, the motor-block is balanced by the counterweights of appropriate weight (steel or cast-iron ingots, cutting logs), placed in specially provided basket in the front of the frame.
The drive wheels of the motor-block is selected of sufficiently large diameter and width to provide less specific ground pressure and better maneuverability of the unit. If necessary to improve traction on wheels easy to put on the lugs of the chains.
Hopes the lens designer when creating tillers, fully justified. The unit was a great help in the hard work in the garden and has been successfully used on the master station, and the neighbor’s work.
