1. Horizontal adjustment left and right. Stop the towing machine with the rotary tiller on the flat ground, lower the rotary tiller and make the blade 5cm away from the ground, observe whether the height of the left and right blade tips is the same from the ground, so as to ensure the same level of the cutter shaft in the operation and uniform tillage depth.
2. Horizontal adjustment before and after. When lowering the rotary tiller to the required depth, observe whether the Angle between the universal joint and the axis of the rotary tiller is close to the horizontal position. If the Angle between the universal joint is too large, the upper tie rod can be adjusted to make the rotary tiller in the horizontal position.
3. Lift height adjustment. In rotary tillage, the Angle between the universal joint shall not be greater than 10 degrees, nor shall it be greater than 30 degrees when the ground turns. Therefore, the lifting of the rotary tiller, for the use of position adjustment of the available screw in the handle at the appropriate position screw limit; When using height adjustment, special attention should be paid to lifting. If you need to raise the rotary tiller again, the power of the universal joint should be cut off.
