Abstract: A lawn mower for directing grass clippings to a grass catcher. The lawn mower includes a vehicle body and a mower unit supported by the vehicle body to be vertically movable for varying a height thereof above the ground. The mower unit includes a housing, cutting blades rotatable about vertical shafts, and a grass clippings discharge channel connected to the housing and opening downward for rearwardly directing grass clippings cut by the cutting blades. The lawn mower further includes a grass collecting duct for connecting a discharge opening of the grass clippings discharge channel to the grass catcher, and a receiving plate having a receiving surface for covering the downward opening of the grass clippings discharge channel.

Abstract: A lawn mower includes front wheels (2), a pair of right and left rear drive wheels (3), a body frame (1), a mower unit (4) supported by the body frame (1) forwardly of the rear drive wheels (3), a grass catcher (60) attached to a rear end of the body frame (1), an engine (7) mounted on the body frame (1), a left change speed device for changing speed of drive from the engine (7), and transmitting the drive to a left axle (3a) of the left rear wheel, a right change speed device for changing speed of drive from the engine (7), and transmitting the drive to a right axle (3a) of the right rear wheel, and a grass collecting duct (63) connected at one end thereof to the mower unit and at the other end to the grass catcher (60). The left change speed device (15, 17) is disposed in a left region of the body frame to extend upward from the left axle (3a). The right change speed device (15, 17) is disposed in a right region of the body frame to extend upward from the left axle (3a).

Abstract: A lawn mower with a vehicle body; an engine mounted on the vehicle body; caster-type front wheels; a rear wheel unit having a left rear drive wheel and a right rear drive wheel; a mower unit disposed between the front wheels and rear wheel unit; a left stepless transmission for transmitting drive, switched between forward drive and backward drive, to the left rear wheel; and a right stepless transmission for transmitting drive, switched between forward drive and backward drive, to the right rear wheel; wherein the right and left stepless transmissions are operable independently of each other. A caster-type auxiliary ground wheel unit (9) is disposed rearwardly of the rear wheel unit and supported by a support member (24) to be vertically movable relative to the vehicle body. A braking mechanism (30) is provided for braking an upward movement of the support member.

Abstract: 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.

Abstract: A mower unit includes a blade housing, and a guide plate for dividing a grass clipping flow space formed in the blade housing, along a flowing direction into a first flow space and a second flow space communicating with each other in a downstream position with respect to the flowing direction. The blade housing has a discharge section for discharging grass clippings cut by cutting blades, in a predetermined direction along with air flows. The discharge section has an intake opening for drawing ambient air into the second flow space. The guide plate may be displaceable relative to the blade housing to vary a sectional passage area of the first flow space.

Abstract: A four wheel drive working vehicle having a hydraulic block for covering one side of a propelling transmission case, an engine, and an HST attached to a side of the hydraulic block remote from the transmission case. The HST includes an input shaft for transmitting drive from the engine, and an output shaft extending through the hydraulic block for transmitting the drive to a transmission line in the transmission case. The vehicle further includes a drive transmission mechanism for selectively transmitting the drive from the transmission line to rear wheels, and a transmission shaft for transmitting the drive between the drive transmission mechanism and the transmission line in the transmission case. The drive transmission mechanism is attached to the side of the hydraulic block where the HST is attached. The transmission shaft extends through the hydraulic block.

Abstract: A mower unit includes a plurality of blade mechanisms each having a blade and a blade shaft fixed to the blade for supporting the blade, pulleys and a belt for transmitting drive among the blade mechanisms, a plate-like support frame for interconnecting the blade mechanisms through intermediate members, a mower deck, and vibration proofing rubber elements disposed between the mower deck and the blade mechanisms.

Abstract: 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.
