First, the components should be inspected before use. In particular, check whether the rotary cutter is equipped with reverse and fixing bolts and the universal joint lock pin is secure. When checking the rotary tiller, the power must be cut off first. When replacing a rotating part such as a blade, the tractor must be turned off.

2. Before the tractor is started, the handle of the rotary tiller clutch should be moved to the separated position. To engage the power in the ascending state, after the rotary tiller reaches the predetermined speed, the unit can start and slowly lower the rotary tiller to make the rotary cutter into the soil. It is strictly forbidden to start directly under the condition of the rotary cutter to prevent the rotary cutter and related components from being damaged. It is strictly forbidden to drop the rotary tiller sharply. It is strictly forbidden to reverse and turn after the rotary cutter has entered the soil.

3. When the ground turning does not cut off the power, the rotary tiller shall not be lifted too high, and the transmission angle of both ends of the universal joint shall not exceed 30 degrees, and the engine speed shall be appropriately reduced. When transferring the plot or walking long distances, the power of the rotary tiller should be cut off and lifted to the highest position to lock.

4. When the rotary tiller is in operation, it is strictly forbidden to approach the rotating parts. There must be no people behind the rotary tiller to prevent the blade from injuring people.

5. In the operation, if the knife shaft is too much, the grass should be parked and cleaned in time to avoid increasing the load on the machine. During the rotary tillage, the tractor and the suspension part are not allowed to be taken in order to prevent accidental injury by the rotary tiller.

6. The rotary tiller is relatively bulky and has a large number of protruding parts. When driving on the road, it should be driven at a low speed and strictly abide by the road traffic rules to avoid accidents such as scraping, rubbing, bumping and bumping. (Xiaohui)
