摘要： A change speed pedal mechanism for controlling a transmission of a working vehicle comprises a first pedal pivotable on an axis extending transversely of a vehicle body, and a second pedal disposed adjacent the first pedal and pivotable on an axis extending longitudinally of the vehicle body. The first pedal is connected to the transmission such that its depression shifts the transmission in a forward accelerating direction. The second pedal includes a linkage arm extending to a position under the first pedal. When the second pedal is depressed, the linkage arm lifts the first pedal, thereby shifting the transmission in a backward accelerating direction.

摘要： A front mower having a grass cutting unit connectable to a front portion and a grass catcher connectable to a rear portion thereof, comprises a main frame structure extending longitudinally of a mower body. The main frame structure includes a pair of right and left front frames and a pair of right and left rear frames. The rear frames have front ends thereof connected to rear ends of the front frames, respectively, such that the rear frames are lower in level than the front frames. A lower auxiliary frame structure is suspended from the main frame structure. Front wheels and rear wheels are supported by the main frame structure. Axles of the rear wheels are swivelable about a vertical axis in a caster-like way to steer the mower. An engine is disposed in a region of the front frames between the front wheels and rear wheels and supported by the lower auxiliary frame structure. The engine and oil pan are disposed above the lower auxiliary frame structure. A driver's seat is disposed above the front frames. A fuel tank is disposed in a region of the rear frames.

摘要： A riding lawn mower comprises a grass cutting unit and a blade housing movable between a substantially horizontal mowing position and an upturned servicing position. The blade housing is suspended by a raising and lowering link mechanism having one end connected to the blade housing and the other end connected to a vehicle body. The blade housing, when raised, is pivotable backward about a connection thereof to the raising and lowering link mechanism, to expose cutting blades mounted therein. This servicing position is maintained by a prop link pivotally connected to one end to the raising and lowering link mechanism, and connectable at the other end to a bracket formed on the housing.

摘要： A cab structure for a working vehicle comprising a driver's seat, and a steering wheel attached to a free end of a curved steering column. The steering column extends forwardly from a front fender located laterally of the driver's seat and then inwardly toward longitudinal centerline of the vehicle body. The steering wheel is pivotable, for positional adjustment, about an axis of the inwardly extending portion of the steering column. The steering column further carries a steering valve at the free end thereof, which is connected to a steering cylinder and a hydraulic pump through hydraulic rubber pipes extending through the steering column.
