Ploughing
When a walking tractor is pulling a one-way double-shaft plow, one drive wheel is on the uncultivated land, and the other drive wheel is in the furrow. The adhesion coefficients between the two wheels and the ground are different, and the slip rate is different, causing the unit to always move. Driving in one direction. For the Dongfeng-12 walking tractor, the following adjustments can be made to solve the problem: adjust the gap between the left and right adjustment screws on the traction frame and the middle connecting frame (swing gap), and adjust the 681 one-way double-shaft plow to 1.5mm From left to right, the 1LS-220 and 701 one-way double-sharp ploughs are adjusted to about 5 mm. In the plowing process, if you find that the tractor is still yaw to the right, loosen the two fastening screws, turn the left adjustment screw's extension part short, and turn the right screw's extension part longer. Until the armrest frame is released, the unit can drive normally along the ditch wall.
Rotary tillage
Possible reasons for skew during rotary tillage operation: the tail wheel is deformed again, the tail wheel shaft is not assembled in the fork, etc. The tail wheel is skewed: the bearing on the tail wheel shaft is damaged or severely worn: the coulter is incorrectly installed or broken or dropped . When the deviation of the rotary tillage operation occurs, the relevant parts should be corrected, repaired, reinstalled or replaced according to the specific situation. Before the problem is solved, try not to use the steering clutch to correct the deviation, but use the method of pushing and pulling the armrest to correct the deviation.
