摘要： A mid-mount mower having a body frame supported above the ground by front wheels and rear wheels, the body frame having a front cross frame in a forward portion thereof with respect to a longitudinal direction of a vehicle body, and a mower unit disposed between the front wheels and rear wheels. A main jack body is mounted on the front cross frame to be pivotable about a pivot shaft extending longitudinally of the vehicle body. The main jack body is in a storage position extending along the front cross frame when pivoted to a first pivot position about the pivot shaft, and in a substantially vertical position relative to the ground when pivoted to a second pivot position about the pivot shaft. The main jack body has a controlled portion exposed upward when the main jack body is in the vertical position. The main jack body is extendible and contractible, in the vertical position relative to the ground, to raise and lower the front cross frame when an operating force is applied through a control device engaged with the controlled portion of the main jack body.
