摘要： 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.

摘要： 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.

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.

摘要： A bidirectional control arrangement for a vehicle comprising a seesaw type pedal including a forward drive depress pad and a backward drive depress pad for controlling a hydrostatic stepless transmission. A down-toe motion of an operator's foot applied to the forward drive depress pad controls the transmission for accelerating the vehicle forward, while a down-toe motion thereof applied to the backward drive depress pad controls the transmission to accelerate the vehicle backward. The forward and backward drive depress pads are spaced apart longitudinally of the vehicle and offset from each other transversely of the vehicle.
