Precautions for the selection of agricultural machinery for wheeled tractors

The matching of farm tools and tractors should be reasonable. When the tractor's efficiency is greater than that of the farm tools, the economic efficiency of the operation will be poor and the farm tools will be easily damaged. When the farm tools are more effective than the tractor, the power of the tractor will be poor, and the operation efficiency of the farm tools will be low or even impossible.

Therefore, when selecting agricultural implements, the supporting power on the operating instructions of the agricultural implements should be consistent with the power of the supporting tractor, and the rotational speed of the agricultural implements must be consistent with the power output rotational speed of the tractor.

Before connecting the farm implement with the tractor suspension mechanism, make necessary adjustments according to the "Farm Implement Instruction Manual". Notice:

1. When the power output shaft of the tractor is working with agricultural tools, the tractor cannot make sharp turns to prevent damage to the universal joint.

2. Before adjusting the farm tools, the clutch of the power take-off shaft must be disengaged, the control handle should be returned to neutral, and the engine should be turned off.

3. Before using the power output shaft to drive the farm tools, check the rationality of the matching of the tractor and the driving farm tools. Generally, during farming, the angle between the power output shaft and the universal joint drive shaft should be no more than 10 degrees. The angle between the output shaft and the input shaft of the farm implement and the transmission shaft should not be greater than 30 degrees. At this time, the height of the rotary tiller blade rolling off the ground should not be less than 250mm. At the same time, it should also be checked whether the safety clutch on the universal drive shaft of the agricultural implement is effective, and the safety clutch should slip under overload conditions.
