Claims

[Scope of claim for utility model registration] ■ Reaping section B connected to the machine A so that it can be raised and lowered by driving.
, a pair of left and right ground-type cutting height detection sensors 9, 9 that can be moved vertically separately are provided, and these sensors 9, 9 and the switching valve (2) of the driving lifting cylinder 6 of the reaping section B are connected to the When both of the sensors 9 and 9 rise above the set value, the switching valve V is switched from the reaping section elevation neutral state to the reaping section upward state, and one of the sensors 9 and 9 rises above the set value. In the cutting height control device of the reaper, which is linked via a mechanism 10 that switches and operates the switching valve V from the reaping part elevation neutral state to before the reaping part descends when the reaping part B descends, the descending speed of the reaping part B is controlled. A mowing height control device for a reaper, characterized in that the mowing height is configured to be smaller than a rising speed. ■ The pair of sensors 9, 9 are arranged on their outer sides [b
The cutting height control device for a reaper according to claim 0, wherein the cutting height is larger than the width of the stump, and the planting height is smaller than the row spacing.
