1. Ploughing operation

In the operation of single-direction double-share plough, one driving wheel is in uncultivated land and the other driving wheel is in furrow. The adhesion coefficient between the two wheels and the ground is different, and the slip rate is different, which leads to the unit steering in the same direction. Agricultural tractors can be adjusted to solve the following: adjust the clearance value between the left and right two adjusting screws and the middle connecting frame (swing clearance), 681 single-share double-share plow to 1.5mm or so, 1LS a 220 and 701 single-share double-share plow to 5mm or so. In the ploughing process, if it is found that the tractor still deviates to the right, the two fastening screws can be loosened, and the extension part of the left adjustment screw can be short, and the extension part of the right screw can be long. Until the release of the handrail frame unit can run normally along the ditch wall.

2. Rotary tillage operation

The possible reasons for the deviation of agricultural tractors in rotary tillage operation are as follows: the tail wheel is deformed again, and the tail wheel shaft is not assembled in place in the fork, so that the tail wheel is deflect: the bearing on the tail wheel shaft is damaged or seriously worn; the plough knife is installed wrong or broken, and falls off. When deviation occurs in rotary tillage operation, relevant parts should be corrected, repaired, reassembled or replaced according to the specific situation. Before the problem is solved, the steering clutch should not be used as far as possible, but the method of pushing and pulling the handrail to correct deviation.

3, sowing operations

Whenagricultural tractor undertakes sowing operation, it is 2 kinds of supporting condition more, it is traction type seeder. The second is synchronous transmission. The main reasons for unit deviation in sowing operation are: the planting head (or ditcher) installation height is inconsistent or asymmetrical in the direction of sowing, the rotation plough configuration and installation occur errors or broken off, the traction frame collision deformation skewed, etc. For the above reasons. During the sowing operation, the resistance varies in the direction of the spread, resulting in torsional torque, which causes the unit to deviate. Therefore, the technical state of the seeder should be carefully checked before the sowing operation, and the rotary cutting plough should be configured and installed according to the provisions, and the seeding head (or ditcher) should be symmetrical. Ensure that the installation height is consistent and meets the agronomic requirements.

4. Harvesting operations

Agricultural tractor is mainly equipped with 4GL - 130 harvester, the main reason of unit deviation: the cutter gap adjustment of harvester cutting width direction is different. The cutting resistance is different: the cutter is high on one side and low on the other, the stubble height is different during harvesting, and the operation resistance is different; Improper selection of cutting width; The ground is uneven. Measures should be taken according to specific causes.
