Claims

[Scope of utility model registration request]

A manual lift lever 10 is operable to sequentially switch the drive lifting mechanism 9 of the reaping part 8, which is connected to the machine 3 so as to be able to rise and fall freely, into a raised state, a neutral raised state, and a lowered state by continuous movement in one direction. , a mechanism that automatically controls the operation of the drive lifting mechanism 9 to maintain the cutting height of the cutting section 8 within a set range based on the detection result of a cutting height detection sensor 11 provided in the cutting section 8; 12, the mowing height control device for a reaper is provided with a lever operation path 19 on the opposite side of the lowering operation position D□ of the manual lifting lever 10 from the side where the lifting neutral operating position N is present. , an automatic operating position A that allows the operation of the control mechanism 12 is provided, and a detent mechanism 23 that can hold the manual lifting lever 10 in position is provided at the automatic operating position A and the neutral lifting/lowering operating position N, respectively. A mowing height control device for a reaper, characterized in that the manual elevating lever 10 is elastically biased to return to the elevating neutral operation position N over the entire range of the path 19.
