The repair and maintenance of agricultural & woodworking machinery is to recover them well working status after long time working, and keep working as soon as possible after problems in agricultural production.

At the same time, the repair and maintenance of agricultural & woodworking machinery is also a quick effect, and potential energy saving measures. Besides, it can promote efficience and reduce the consumption of agricultural machinery operation to realize the energy conservation and emissions reduction of agricultural production. According to the survey, failing to the repair and maintenance of agricultural machinery, the average horsepower in  hours of fuel consumption will be about 20% higher than the rated fuel consumption; if the engine maintains normal, and testing maintenance is in time, it can effectively reduce power, low consumption of fuel, and decrease the 2% ~ 5% of emissions. Therefore, the repair and maintenance of agricultural machinery is not only of great benefit to energy conservation and emissions reduction, but also can reduce effectively the farmer's operating costs. So,it is necessary to have the repair and and maintenance in the use of agricultural machinery management.
