1. Horizontal adjustment on both sides. Park the tractor with a rotary tiller on a flat surface, lower the rotary tiller so that the blade is 5 centimeters above the ground, and observe whether the height of the left and right blade tips from the ground is consistent to ensure that the blade axis is level and the plowing depth is even during the operation.
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 first axis of the rotary tiller are close to the horizontal position. If the angle between the universal joints is too large, the upper pull rod can be adjusted to keep the rotary tiller in a horizontal position.
3. Lift height adjustment. In rotary tillage operations, the angle between the universal joint is not allowed to exceed 10 degrees, and it is also not allowed to exceed 30 degrees when turning on the ground. Therefore, for the lifting of rotary tillers, screws can be used to adjust the position by tightening the limit at the appropriate position of the handle; When using height adjustment, special attention should be paid when lifting. If it is necessary to raise the rotary tiller again, the power of the universal joint should be cut off.
