1. Steering Mechanism: The steering mechanism is essential for controlling and changing the direction of the tractor, directly impacting its safety. Therefore, it's crucial to inspect this system thoroughly to ensure it's in optimal working condition. Key Points to Check: 1. Inspect the tightness of components like the tie rod, steering arm, and steering base, as well as the locking of split pins. Loose connections can lead to dangerous situations. 2. Check the pre-tightening of the steering shaft by pushing and pulling the steering wheel along its axis. There should be no noticeable play or shaking. 3. Ensure the steering wheel has a play clearance between 15 and 30 degrees. If it's too much or too little, adjust it promptly to maintain control. 4. Lubricate the ball joints with grease regularly to prevent wear and ensure smooth operation. 5. If any parts of the steering system are cracked or damaged, do not attempt to weld them. Replace them immediately with new ones. 6. When parking, make sure the steering doesn't lock up or become stuck, which could affect maneuverability. 7. If you experience vibration, drifting, or difficulty in steering while driving, stop and repair the issue immediately—do not continue driving. 8. If the steering feels "sinking" during use, investigate the cause quickly. It may indicate fluid leakage or internal damage that needs attention. 2. Braking System: The braking system is vital for slowing down or stopping the tractor safely. A properly functioning brake system is critical for road safety and must be inspected regularly. Important Checks: 1. Examine the brake lines for wear, leaks, and secure connections. Pay special attention to areas where the pipes might rub against the frame or bridge. 2. Check the brake fluid level. If it's low, top it up using the same type of fluid to avoid compatibility issues. 3. Measure the free travel of the brake pedal, which should be around 10–15 mm. Adjust if necessary to ensure proper function. 4. If the brake pedal feels soft or sinks, it may indicate air in the system, oil leaks, or internal problems in the master cylinder. Address this immediately. 5. Weak braking could result from excessive drum clearance, hardened brake pads, or improper drum alignment. These issues need prompt correction. 6. A spongy feel on the brake pedal usually means there's air in the system. Bleed the brakes to remove the air. 7. Watch out for brake drag or runaway conditions. These can cause overheating and reduce braking efficiency. 8. After driving, touch the wheel hubs to check their temperature. They should all be roughly the same. If one is excessively hot, it may indicate a faulty brake; if cold, the brake may be weak. 3. Chassis and Suspension System: The chassis and suspension system form the structural framework of the tractor, consisting of the frame, axles, wheels, and suspension components. Regular inspection is essential to maintain stability and safety. Key Inspection Steps: 1. Check the tightness of the frame and axle bolts. Any looseness can compromise the tractor’s structure. 2. Monitor tire pressure and tread wear. Uneven wear may signal alignment or suspension issues. Always keep tire pressure within the manufacturer’s recommended range. 3. Inspect the bearing preload on each wheel hub. Grasp the top of the wheel and pull it—there should be no noticeable play. 4. When adjusting the front wheels, check the kingpin clearance and ensure it's properly lubricated. 5. Look for broken leaf springs and apply grease to the spring pins regularly to prevent failure. 6. Visually inspect the tractor after parking. Check that both front wheels are aligned and in the correct position. 4. Transmission System: The transmission system transfers power from the engine to the drive wheels. It includes the clutch, gear box, drive shaft, and rear axle. Each component requires regular maintenance. Clutch: a. Check the clutch pedal free travel, which should be approximately 25–35 mm. Adjust if needed. b. Monitor for slippage, incomplete disengagement, or rough engagement during operation. Transmission Gearbox: a. Inspect for oil leaks and ensure all seals are intact. b. Listen for unusual noises or shifting problems. If gears are worn or bearings are damaged, repair or replace them. c. After driving, check the temperature of the gearbox. It should be warm but not too hot. If it's too hot, check the oil level and quality. d. Unusual noises from the gearbox may indicate worn gears or bearings. Low oil levels can also cause noise. Drive Shaft: a. Tighten the flange bolts at both ends of the drive shaft if they are loose. b. Apply grease to the cross shaft and ensure all needle bearings are properly lubricated. Avoid over-greasing the universal joint to prevent damage to the dust cover. Rear Axle: a. Check for oil leaks from the rear axle housing. b. After use, check the temperature of the rear axle. If it's too hot, check the oil quantity and quality and top up or replace as needed. c. Listen for abnormal noises from the rear axle. Worn gears or improper bearing preload can cause these sounds. d. To check the total gear clearance, lift the rear wheels, set the handbrake, and manually rotate the shaft. Use visual or tactile methods to assess the gap.
