ABSTRACT:
A device for adjusting the height of a vehicle, by rotating the angle of a base shaft eccentrically supporting a support shaft. Wheels are fitted to a support shaft eccentrically connected to a base shaft rotatably supported by bearings disposed on push-pull type electric mowing machine. One of the ends of a connecting member is fixed to the core of the base shaft and an adjustment device is fitted to the other end of the connecting member. Alternatively, a base shaft is supported concentrically and rotatably at the core of a composite shaft type mowing machine in such a manner as to protrude from both end portions of a rotary shaft. The base shaft is rotatably supported by an apparatus main body at both end portions of the base shaft and eccentrically with respect to the base shaft, and wheels are fitted to both end portions of the support shaft. An adjustment pulley is fixed to the base shaft either inside or outside the bearings. The position of the height is adjusted by controlling this adjustment member.
