1. At the beginning of the operation, the rotary cultivator should be in an elevated state, and the power output shaft should be combined to increase the speed of the cutter shaft to the rated speed, and then the rotary cultivator should be lowered so that the blades are gradually inserted into the soil to the required depth. It is strictly prohibited to combine the power output shaft or descend the rotary cultivator sharply after the blade enters the soil, so as to avoid bending or breaking the blade and increase the load of the tractor.
2. In the operation, the speed should be as low as possible, so that the quality of the operation can be ensured, the soil can be finely broken, and the wear of the mechanical parts can be reduced. Pay attention to whether there are noises or metal percussions from the rotary tiller, and observe the condition of broken soil and tillage depth. If there is any abnormality, the machine should be shut down immediately for inspection, and the operation can be continued after troubleshooting.
3. When turning on the ground, work is prohibited. The rotary tiller should be raised to keep the blades off the ground and the tractor throttle should be reduced to avoid damage to the blades. When lifting the rotary tiller, the inclination angle of the universal joint should be less than 30 degrees. If it is too large, it will produce impact noise, which will cause premature wear or damage.
4. When reversing, crossing ridges and transferring plots, the rotary tiller should be raised to the highest position and the power should be cut off to avoid damage to the parts. If it is transferred to a distant place, the rotary tiller must be fixed with a locking device.
5. After each shift, the rotary tiller should be maintained. Remove the dirt and weeds on the blade, check the tightness of each connecting piece, add lubricating oil to each lubricating oil point, and add butter to the universal joint to prevent aggravation of wear.
