1、Overload operation, the diesel engine work rough sex, exhaust smoke and produce a large amount of carbon deposit, at the same time, the engine temperature, lubrication condition, fuel oil aging and wear parts.

2、Don't work overload operation, adjustment, a sharp drop in engine speed, fuel consumption increase, power down.

3、Engine speed is not stable, even parking stall occurs, the pilot had to shift work, often make the shift number increase, both increase the wear parts, reduce the service life, and make drivers working strength increases, easy fatigue. Please note: the engine overload, tractor may not overload.

4、When caused by traction resistance or trailer overload long-term overworked, the diesel engine driving the tractor is in overload condition, the service life of tires to not only significantly decreased, chassis parts and easy to damage.
