Rotary tillage operation
Possible reasons for steering deviation in rotary tillage are as follows: the tailwheel deforms again, the tailwheel shaft is not properly assembled in the fork, etc., so that the tailwheel deflection is caused; the bearing on the tailwheel shaft is damaged or seriously worn; the plough knife is installed wrongly, broken or dropped. When rotation tillage operation deviates, the relevant parts should be corrected, repaired, reinstalled or replaced according to the specific situation. Before solving the problem, should try not to use the steering clutch to rectify the deviation, but with the method of pushing and pulling the handrail frame to rectify the deviation.
Planting operation
Walking tractor for sowing operations. There are two kinds of supporting conditions: one is traction seeder. The second is the rice and wheat drill with synchronous transmission. The main reasons of unit deviation in seeding operation are as follows: the seeding head (or ditch opener) installation height is not consistent or left and right asymmetry in the seeding direction, the rotary cutting plough is arranged and installed in error or break off, traction frame collision deformation deflection, etc.
For the above reasons. The seeding operation in the direction of the seeding resistance is not equal, produce torsion torque, causing the unit to drive off. Therefore, the technical status of seeder should be carefully checked before seeding operation, rotary cutting plough should be arranged and installed according to the provisions, and seeding head (or trencher) should be arranged symmetrically. Ensure the installation height is consistent and meets the agronomic requirements.
