Hydraulic oil is the starting point of the straw baler. Before using the hydraulic oil of the straw baler, the hydraulic oil must be kept clean. Before use, the hydraulic oil may be contaminated by the outside world or have errors in the storage process. Therefore, pay attention to the state of the oil before filling the oil. If problems are found, it should be dealt with in time. The working procedure of the traditional straw baler when changing the production variety is very cumbersome, and it takes a lot of time to prepare, which has greatly reduced the production efficiency, so the equipment modification process fully considers its adaptation Sex, can let it use its own value as much as possible to meet the needs of production. After many attempts, the automatic straw baler has now changed the previous production method, greatly reducing the production efficiency, and simplifying the working procedures of the equipment.
