業が可能となって、調節作業が行い易いものとなる。According to a first aspect of the present invention, a plurality of pin holes for adjusting the ground posture are provided at a lower end portion of the suspension rod, and the lower end portion of the suspension rod is cut. The blade housing is made to project into a space surrounded by a vacuum plate provided along the rear portion of the rotation trajectory of the blade and a rear wall of the cutting blade housing. [Operation] As shown in FIG. 2, the gauge wheel 7 at the front of the mower M
In order to adjust the ground posture of the mower M horizontally as the height of the mower M is adjusted, the connecting pin 22 that connects the lower end of the hanging rod 15 and the bracket 20 of the cutting blade housing 6 is pulled out to suspend the hanging rod. 15 is moved up and down to move the predetermined pin hole 15
The connecting pin 22 is replaced with a. [Effect] As described above, a plurality of adjusting holes are provided at the lower end of the hanging rod, and the adjusting plate is provided with a vacuum plate and a cutting blade housing provided along the rear part of the rotation trajectory of the blade in the cutting blade housing. Since it is designed to rush into the dead space surrounded by the rear wall, even if a hole for adjustment is provided in the lower part of the hanging rod, the length of the hanging rod is not obstructed by the upper wall of the cutting blade housing. It is possible to adjust the height, and by doing so, it is possible to position the adjustment hole at a position far away from the lower surface of the machine body, work in a wide space is possible, and adjustment work is facilitated.
