The gearbox of the tractor consists of a clutch pedal, a push rod, an interlocking shaft, a spring, a lock pin, a slide bar, and the like. Paying attention to the use and maintenance of these parts will not only prolong their service life, but also reduce many accidents. Ensure the normal operation of the locomotive. 1. When shifting gears, pay attention to the clutch on the way to the end, completely cut off the power, to prevent the gear from impacting and gearing when shifting gears to reduce gear damage. 2. When shifting gears, pay attention to pushing the shift lever into position so that the gears are all meshed so that the teeth do not become tapered and cause automatic gear shifts. 3. During the locomotive work, pay attention to the oil level and temperature of the gearbox and whether there is any abnormal noise. If the shell temperature is higher than 70°C--80°C, it means that some parts of the gearbox are not working properly, and should be stopped to check and eliminate. 4. When the wheel-type tractor is shifting gears in progress, when shifting high gears to lower gears, attention should be paid to the combination of operating skills and accelerator speeds to prevent gearing. 5. In winter, the viscosity of the gear oil is large, so be careful not to add a load or high-speed driving at a low temperature, so as to avoid poor lubrication and to accelerate the wear of the parts or damage the gears. 6. When the gear is engaged, if the clutch is still difficult to file after the clutch is completely disengaged, it is because the gear teeth of one gear in the gearbox face the gear teeth of the other gear. At this time, pay attention to slightly lift the clutch pedal, let the gear turn a certain angle, and then separate the clutch and re-file. Must not force file, so as not to damage the gear. 7. Be careful to check fasteners and operating mechanisms frequently, and tighten them at any time. 8. Note that different lubricants are used in winter and summer. The gearbox should be cleaned once every 500 hours of operation and replaced with new gear oil. Pay attention to the cleanliness of the oil when refueling, release the gear oil while hot, then add the new diesel, idle for 2 minutes at low speed. In 3 minutes, the net diesel is finally put and new gear oil is added.
