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 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 mid-mount mower having a body frame supported above the ground by front wheels and rear wheels, the body frame having a front cross frame in a forward portion thereof with respect to a longitudinal direction of a vehicle body, and a mower unit disposed between the front wheels and rear wheels. A main jack body is mounted on the front cross frame to be pivotable about a pivot shaft extending longitudinally of the vehicle body. The main jack body is in a storage position extending along the front cross frame when pivoted to a first pivot position about the pivot shaft, and in a substantially vertical position relative to the ground when pivoted to a second pivot position about the pivot shaft. The main jack body has a controlled portion exposed upward when the main jack body is in the vertical position. The main jack body is extendible and contractible, in the vertical position relative to the ground, to raise and lower the front cross frame when an operating force is applied through a control device engaged with the controlled portion of the main jack body.

摘要： A rear discharge type mower apparatus includes a blade housing, a support shaft supported by the blade housing, a rotatable blade supported by the support shaft, and a front guide plate having a shape extending substantially along the rotation path of a corresponding blade. The front guide plate forms an opening for ejecting cut grass rearwardly and has a downstream plate portion located in a downstream position with respect to a rotating direction of the corresponding blade and having an end defining one end of the opening. The downstream plate portion extends rearwardly of the blade housing and a distance from a center of rotation to the downstream plate portion is progressively decreased toward a rear end of the blade housing. At least a part of the downstream plate portion is located radially inside of the rotation path of the corresponding blade.
