摘要： A mid-mount type lawn tractor having idle wheels disposed at one end in a fore and aft direction of a vehicle body, drive wheels disposed at the other end in the fore and aft direction of the vehicle body, a mower unit connected to the vehicle body between the idle wheels and drive wheels. The lawn tractor includes a wheel support frame supporting the idle wheels and pivotably connected to the vehicle body. A pivotal movement of the wheel support frame relative to the vehicle body displaces the idle wheels relative to the vehicle body, to produce a running posture or a jack-up posture lifting at least part of the vehicle body. The pivotal movement of the wheel support frame is caused by a jack device.
