Small four-wheel tractors are essential for agricultural tasks, but they can sometimes experience issues with steering and movement. One common problem is that the tractor is difficult to turn or cannot turn at all, either moving straight continuously or failing to respond properly when turning. This issue often stems from problems within the differential system.
The primary cause of this malfunction is usually a stuck differential planetary gear shaft, which prevents the two planetary gears from functioning correctly. As a result, the differential loses its ability to adjust the rotation speed between the wheels, leading to the tractor only being able to move straight. To fix this, it's necessary to replace the differential planetary gear shaft, the two planetary gears, and their thrust washers. Additionally, the gear oil should be changed to ensure proper lubrication and performance.
Another common issue occurs when the tractor struggles with both straight movement and turning. In such cases, the problem may be due to poor-quality roller bearings in the steering gear assembly. Over time, these bearings can wear out significantly, causing the roller to become misaligned between the worm gear and the worm. This misalignment can lead to damage, such as the worm wheel and worm becoming jammed, which affects the overall operation of the tractor.
To resolve this, the steering gear assembly must be disassembled, and the upper and lower single-row radial ball bearings should be replaced. It’s also important to clean all the parts thoroughly and apply calcium-based grease to the head. When replacing the bearings, it's crucial to inspect them carefully for any signs of cracks or damage. Regular maintenance and checking the axial clearance of the bearings can help prevent excessive wear and extend the life of the tractor.
In addition to regular inspections, users should follow the manufacturer's guidelines for maintenance and lubrication. Proper care ensures that the tractor operates smoothly and efficiently, reducing the risk of mechanical failures during use.
