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 reel-type cutting unit including a reel blade for cutting grass in cooperation with a fixed blade. The reel blade is rotatable about a horizontal axis extending transversely of a vehicle body, to move from front to rear relative to the fixed blade with respect to a forward traveling direction of the vehicle body. The cutting unit has a main case surrounding the reel blade to define a space for carrying grass clippings in a rotating direction of the reel blade to a top level of the reel blade. A guide member is connected to the main case for receiving the grass clippings carried to the top level. The guide member defines a grass receiving space having a grass discharge opening. The grass discharge opening is connected to a grass catcher through a duct.

摘要： A mower unit attachable to a vehicle body includes a mower deck. The mower deck defines a grass discharge opening at an opposite side of one side wall, and has a plurality of rotary blades juxtaposed inside the mower deck to be rotatable about vertical axes. All of the rotary blades are rotatable in the same direction so that a front half, with respect to a traveling direction, of a track of rotation of each rotary blade points toward the side having the grass discharge opening. A rear baffle depends from a top board of the mower deck for enclosing the rotary blades in combination with a front wall, and surrounds, in form of a concentric part circle, a rear portion of the track of rotation of each rotary blade. A front baffle and a mulching baffle are provided to be selectively attached to the mower deck to be located forwardly of the tracks of rotation of the rotary blades. The front baffle includes curved segments each for surrounding, in form of a concentric part circle, a front portion of the track of rotation of one rotary blade, and counter curved segments for connecting the curved segments. The mulching baffle, in combination with the rear baffle, defines a mulching chamber surrounding the track of rotation of each rotary blade.
