摘要： A lawn mower having a driver's section and a grass cutting unit forwardly of a vehicle body; an engine mounted between front and rear wheels; and a pair of main frames extending longitudinally of the vehicle body, each of the main frames including a front frame member, and a rear frame member connected to the front frame member and disposed at a lower level than the front frame member. The engine is mounted below the main frames between the front and rear wheels, and has a radiator disposed rearwardly of the engine and having an upper portion projecting upwardly of the rear frame members. The engine is surrounded by a first cover assembly including side covers depending respectively from the main frames, lower covers connecting the respective side covers to lower positions of the engine, and a front cover for closing an area forwardly of the engine. The first cover assembly defines first ambient air intake openings. A second cover is disposed rearwardly of the driver's section for covering the upper portion of the radiator. The second cover defines a second ambient air intake opening in a forward portion thereof. Cooling air flows produced by a fan disposed adjacent the radiator are drawn through the first and second ambient air intake openings, at least a large part of the cooling air flows being exhausted rearwardly through the radiator.

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 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.
