1. Steering Mechanism: The steering mechanism is crucial for controlling and changing the direction of the tractor, directly impacting its safety. A thorough inspection of the steering system is essential to ensure it operates smoothly and reliably. Any issues should be addressed immediately to avoid potential hazards. Key points to check: 1. Inspect the tightness of components such as the tie rod, steering arm, and steering base, and ensure that the split pins are properly secured. 2. Check the axial pre-tightening of the steering shaft by pushing and pulling the steering wheel. There should be no noticeable play or wobbling. 3. Ensure the steering wheel's free play is within 15–30 mm. If it’s too much or too little, adjust it promptly. 4. Lubricate the ball joints with grease regularly to maintain smooth operation. 5. If any cracks or damage are found in the steering parts, do not attempt to weld them—replace them with new ones instead. 6. When parking, make sure the steering does not lock unexpectedly. 7. If you experience vibration or steering drift while driving, stop and repair the issue immediately—do not continue driving until it is fixed. 8. If the steering feels unstable or sinks during use, investigate the cause and resolve it quickly to prevent further damage. 2. Braking System: The braking system is vital for slowing down or stopping the tractor safely. It plays a major role in road safety, so regular checks are necessary to ensure everything functions correctly. Important checks: 1. Examine the brake pipes for wear and secure connections. Pay special attention to whether they are rubbing against the frame or other components. 2. Check the brake fluid level. If it’s low, top it up with the same type of fluid. 3. Ensure the brake pedal has a free travel of 10–15 mm. Adjust if it’s too high or too low. 4. If the brake pedal feels soft or sinks, it could indicate a leak in the system, such as in the master cylinder or brake lines. Investigate and fix it immediately. 5. Weak braking may be caused by excessive drum clearance, hardened brake pads, or misalignment of the brake drum. 6. A spongy feel when pressing the brake pedal often means there’s air in the system. 7. Address any issues like brake drag or runaway brakes right away. 8. After driving, touch each wheel hub to check the temperature. They should all feel roughly the same. If one is unusually hot, there may be a problem with the brake drum; if it's cold, the brake might be weak. 3. Drive System: The drive system serves as the structural backbone of the tractor, consisting of the frame, axles, wheels, and suspension. Regular inspections are needed to keep everything in good working order. Things to check: 1. Make sure the frame and axle are securely fastened. 2. Check tire pressure and tread wear. If the tires show uneven wear, identify the cause and fix it. Always maintain proper tire pressure regardless of load or road conditions. 3. Verify the preload on the wheel bearings by gripping the top of the wheel and pulling. There should be no noticeable play. 4. When turning the front wheels, check the kingpin clearance and ensure it is well lubricated. 5. Inspect the leaf springs for cracks and apply grease to the spring pins as needed. 6. Stand in front of the parked tractor and visually inspect the body alignment, checking both front wheels for symmetry. 4. Transmission System: The transmission system transfers power from the diesel engine to the drive wheels. It includes the clutch, gearbox, drive shaft, and rear axle. Each component requires regular maintenance. 1. Clutch: a. Check the free travel of the clutch, which should be around 25–35 mm. Adjust if necessary. b. Monitor for slippage, incomplete disengagement, or rough operation during use. 2. Gearbox: a. Look for oil leaks. b. Check for unusual noises, gear detachment, or other faults. Repair as needed. c. After driving, test the temperature of the gearbox. If it's too hot to touch, it may indicate low or degraded gear oil. Top up or replace as required. d. Listen for abnormal noises during driving, which could signal worn gears or bearings. Low oil levels can also cause noise. 3. Drive Shaft: a. Inspect the flange bolts at both ends of the drive shaft. Tighten if loose. b. Apply grease to the cross shaft and ensure all needle bearings are lubricated. Avoid over-greasing the universal joint to prevent damage to the dust cover. 4. Rear Axle: a. Check for oil leaks. b. After use, gently touch the rear axle housing to check its temperature. If it’s too hot, inspect the gear oil quantity and quality, and add or replace it if needed. c. Listen for unusual noises during driving. Worn main reduction gears or improper cone bearing preload can cause abnormal sounds. d. To check the total gear clearance, lift the rear wheels, set the handbrake, and manually rotate the axle to visually or physically measure the gap.
