Abstract: A mid-mount type lawn tractor having idle wheels disposed at one end in a fore and aft direction of a vehicle body, drive wheels disposed at the other end in the fore and aft direction of the vehicle body, a mower unit connected to the vehicle body between the idle wheels and drive wheels. The lawn tractor includes a wheel support frame supporting the idle wheels and pivotably connected to the vehicle body. A pivotal movement of the wheel support frame relative to the vehicle body displaces the idle wheels relative to the vehicle body, to produce a running posture or a jack-up posture lifting at least part of the vehicle body. The pivotal movement of the wheel support frame is caused by a jack device.

Abstract: A riding mower includes a pair of right and left propelling wheels, an engine disposed rearwardly of axles of the propelling wheels, a pair of right and left transmission cases corresponding to the propelling wheels and supporting the propelling wheels, respectively, a pair of right and left HSTs coupled to the transmission cases for outputting power thereto, respectively, a center case housing a power distributor for transmitting power from the engine to the pair of right and left HSTs, and a mower unit disposed forwardly of the propelling wheels. The center case is disposed forwardly of the axles of the propelling wheels.

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 lawn tractor includes a vehicle body, a center reel-type cutting unit, and side reel-type cutting units arranged laterally of the center reel-type cutting unit with respect to a moving direction of the vehicle body, wherein a cutting track by the center reel-type cutting unit and cutting tracks by the side reel-type cutting units partly overlap one another. A first lift mechanism vertically movably connects the center reel-type cutting unit to the vehicle body, wherein the first lift mechanism is operable to raise and lower the center reel-type cutting unit without displacing the center reel-type cutting unit transversely of the moving direction. Second lift mechanisms vertically movably connect the side reel-type cutting units to the vehicle body, respectively, wherein the second lift mechanisms are operable to raise and lower the side reel-type cutting units without displacing the side reel-type cutting units transversely of the moving direction.

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 reel mower having side reel mower units and a center reel mower unit connected to a vehicle body to be vertically movable between a lower position for a grass cutting operation and an upper position for a non-operational run. The side reel mower units and center reel mower unit have reels driven by reel drives under control of a control mechanism. A forcible stopping device is provided for forcibly stopping the reel drives of the reel mower units with priority over control of the reel drives by the control mechanism when the side reel mower units and center reel mower unit are all in the upper positions.

Abstract: A front-mount mower tractor including a front axle case, a driver's platform disposed above the front axle case and in a front region of the tractor, a platform support frame having one end thereof fixed to the front axle case and extending under the driver's platform longitudinally forwardly of the tractor, and a mower unit raising and lowering link mechanism. The mower unit raising and lowering link mechanism includes lift links pivotally connected to the front axle case for suspending a mower unit from free ends thereof, lift arms pivotally connected to the front axle case above the lift links, at least a portion of each lift arm extending along a side surface of the platform support frame, connecting links each pivotally connected at one end thereof to one of the lift arms, and at the other end to one of the lift links, at least a portion of each connecting link extending along a side surface of the platform support frame, and a cylinder for swinging the right and left lift arms.
