Large tractors are indispensable tools for farmers, used for all kinds of heavy farm work every season. They work long hours in dusty, bumpy farmland and pull heavy farm tools, which will slowly wear out internal parts. Doing regular maintenance on time can keep tractors working smoothly and make them last longer. Different from ordinary cars that get maintained by fixed dates, farm tractors mainly take engine working hours as the standard for maintenance, as this standard can better reflect the real loss caused by field work.
Daily and weekly visual checks are the most basic maintenance work. Before starting work every day, drivers need to check key liquids like engine oil and coolant, and look for liquid leakage or strange sounds from the machine. Weekly maintenance includes adding grease to all moving parts, tightening loose belts, cleaning blocked filters and checking firm battery connections. These simple repeated checks can find small hidden problems early, so tractors won't break down suddenly during busy farming seasons.
When the tractor runs for 250 hours, a full set of routine maintenance is needed. Workers will change old engine oil and matching filters, clean air and fuel filters that are filled with dirt, and tighten loose bolts on the chassis. Finishing these jobs
on time can reduce engine wear, so the tractor can keep stable power when bearing heavy farm tasks.
There are two important deep maintenance points at 500 hours and 1000 hours. For the 500-hour maintenance, workers adjust engine valve clearance, test whether brakes work normally and check the state of hydraulic oil. Once the tractor hits 1000 working hours, a full machine inspection is required: replace transmission oil and hydraulic oil, check if the chassis structure is safe, clean the dirt accumulated in DPF, and test all safety devices. Following this layered maintenance plan can greatly reduce the chance of machine damage and cut down long-term repair costs.
