ンパクト化並びに、コスト低下を図ることができる。As is apparent from the above embodiments, according to the present invention, the pretreatment device at the front part of the mowing section (8) moves left and right, and the mowing input shaft case (23) at the rear part of the mowing section (8). Further, a transmission case (29) for transmitting power to the pretreatment device is provided, and the transmission case (29) is rotatable left and right in conjunction with the left and right movement of the pretreatment device, and the front end of the transmission case (29) and the pretreatment device. Positioning device for pretreatment device (52)
(52a) is provided, so this position fixing device (52)
(52a) can be prevented from becoming non-functional without adhering to soil, the pretreatment device can be properly moved left and right, and the position can be fixed at the left and right moving position, and the cutting unit (8) can be made light and compact, and The cost can be reduced.
