Small four-wheel tractors are difficult to turn or cannot turn at all. There are two situations:

First, you can only go straight, you can't turn at all. The main reason is that the differential planetary gear shaft and the two planetary gears are stuck together, so that the differential loses the differential effect, the tractor can not turn, and can only travel straight. Solution: First replace the new differential planetary gear shaft with two planetary gears, as well as the thrust washers of the two planetary gears, and replace the gear oil.

Second, the tractor has difficulty in driving straight or turning. The main reason is that the quality of the roller bearing on the steering gear assembly is unqualified. The roller is detached between the worm wheel and the worm. Because of the long-term use, the bearing wears seriously, and even the loose frame, the worm wheel and the worm are stuck, and the steering wheel cannot rotate normally. Solution: Disassemble the steering gear assembly, replace the upper and lower single-row radial ball bearings, and clean the steering gear parts and re-inject the calcium-based grease. When replacing the bearing, carefully check the bearing for defects such as fine cracks. During the use of the tractor, the axial clearance of the bearing should be regularly checked and adjusted to prevent the bearing from being excessively worn due to excessive clearance.
