How should the rotary tiller be adjusted before use?

1. Left and right horizontal adjustment. Stop the tractor with the rotary tiller on a flat ground, lower the rotary tiller so that the blade is 5 cm from the ground, and observe whether the height of the left and right blade tips is consistent to ensure that the blade axis is level and the tillage depth is uniform during operation.
2. Front and rear horizontal adjustment. When the rotary tiller is lowered to the required tillage depth, observe whether the universal joint angle and the rotary tiller axis are close to the horizontal position. If the universal joint angle is too large, adjust the upper pull rod to make the rotary tiller in a horizontal position.
3. Lifting height adjustment. During rotary tillage operation, the universal joint angle is not allowed to be greater than 10 degrees, and it is not allowed to be greater than 30 degrees when turning at the head of the field. Therefore, for the lifting of the rotary tiller, for those using position adjustment, the limit screw can be screwed at the appropriate position of the handle; for those using height adjustment, special attention should be paid when lifting. If the rotary tiller needs to be raised again, the power of the universal joint should be cut off.
