Tractor is a self-propelled power machine used to pull and drive working machinery to complete various mobile operations. It can also be used for fixed operation. Tractor rear suspension mechanism is an indispensable important tool in agricultural production, so how to use it?

1) When the tractor carries the long-distance transportation with the hanging agricultural machinery, the central pull rod should be shortened, and the machinery should be adjusted to the * high position, and then the agricultural machinery should be fixed, and the limit chain should be tight. In the process of long-distance driving, it is necessary to closely observe whether there is obvious settlement phenomenon of agricultural machinery and equipment, and take timely measures to fix the settlement machinery. It is forbidden to use the positioning clamp block to press the positioning valve to prevent the agricultural machinery from sinking. At the same time, it is forbidden for the tractor to suddenly turn or cross the obstacles in the process of driving with agricultural machinery to avoid damaging the agricultural machinery and equipment.

2) When the tractor suspends small or small agricultural machinery and equipment with small lateral swing range for operation, such as for tillage operation and sowing operation, the connection between agricultural machinery and tractor generally adopts three-point suspension, which allows a small range of swing relative to the tractor in the process of agricultural machinery operation, so as to ensure that the agricultural machinery and equipment can move stably with the tractor in a straight line.

3) If the hanging agricultural machinery and equipment are equipped with ground wheel or depth limiting wheel, the distributor must choose to use floating position to work. For the soil with large hardness, the pressure drop equipment is only used when the mechanical equipment is buried in the soil for a short time to avoid damaging the agricultural machinery and equipment; In the formal operation of the tractor, the length of the central pull rod can be changed to adjust the front and rear horizontal position of the agricultural machinery. The left and right horizontal position of the agricultural machinery can be changed by adjusting the position of the left and right diagonal pull rod. When the position is adjusted to a suitable position, the nut after adjustment should be tightly locked to avoid damaging the mechanical equipment.

4) When the tractor hangs large or wide agricultural machinery and equipment, such as ploughing, ploughing and ditching, it usually adopts two-point suspension, which allows the agricultural machinery to have a larger swing relative to the tractor, so as to ensure that the agricultural machinery and equipment can better adapt to the direction of the tractor.
