Abstract: A grass mower includes a cutting height adjustment mechanism for adjusting a cutting height of a mower unit via a lift link mechanism. The cutting height adjustment mechanism has a cutting height control grip disposed upwardly of the fender unit and on one outer side of the driver's seat in the vehicle body transverse direction, a cam body disposed downwardly of the fender unit and closer to a center of the vehicle body in the vehicle body transverse direction than the cutting height control grip, a rotational rod extending obliquely through the fender unit and connecting the cutting height control grip with the cam body, and a stopper body for selectively determining a cutting height of the mower unit in association as it comes into contact with one of a plurality of contact faces formed in the cam body.

Abstract: [Summary] A mower unit receiving power transmitted from a drive source includes a blade pulley mounted on a blade rotational shaft, an idle pulley unit, and a single belt routed around an output pulley of the drive source, the idle pulley unit and the blade pulley. The pulley height of the idle pulley unit is set higher than the pulley height of the blade pulley, and a belt portion of the belt running between the output pulley and the idle pulley unit extends to pass over and above the other belt portion.

Abstract: A self-propelling work vehicle for forward and reverse drive includes a handle unit attached to the vehicle body for a first shift movement along a first direction with a neutral position and a second shift movement from the neutral position along a second direction intersecting the first direction. Forward drive speed or reverse drive speed is determined based on the first shift movement. A guide unit attached to the vehicle body includes a maximum forward speed guide member for defining a shift movement end of the handle unit determining a maximum forward speed of the forward drive speed, and a neutral guide member for guiding the second shift movement of the handle unit from the neutral position defined as a starting position. The maximum forward speed guide member and the neutral guide member are positionally adjustable independently of each other.

Abstract: There is provided a work vehicle including: an engine in which a pulley for transmitting power is fitted to an output shaft disposed in such a manner as to project downward from a bottom; and a mount surface at which an opening, into which the pulley can be inserted, is formed, and further, on which the engine is mounted in the state in which the pulley is inserted into the opening from above. The work vehicle is further provided with a fixed plate that is fixed to the bottom of the engine and joined to the mount surface so as to fix the engine onto the mount surface. The output shaft is inserted through the fixed plate, and further, the fixed plate is interposed between the bottom of the engine and the pulley.
