When the tractor rotary blade is at the same phase angle, one blade must be immersed in the soil to ensure the working stability and the average load of the blade shaft. If more than two blades are configured, the amount of soil cutting should be equal to achieve good quality of crushed soil. The main reasons for the flat bottom of the ditch are that the material was not cut strictly according to the drawings, the process tooling for production and processing was unqualified, and the management system was not perfect.
The maintenance of the rotary tiller. There will be holes for filling grease on the top and side of the rotary tiller. Personally, it is recommended to stop the filling of grease once a day during the work trip to meet the needs of high-speed rotation for lubrication, and also to remove impurities. Grease cleaning reduces internal wear; moreover, there will be a transmission box in the middle of the rotary tiller, which requires gear oil lubrication due to the large load of the transmission box. Generally speaking, the quantity of gear oil in the transmission box of the newly purchased rotary tiller is insufficient, and you need to supplement it yourself. So as not to cause excessive wear and tear on the transmission case, the lubrication will affect the service life.
