A work vehicle includes a pair of left and right pivotal connecting units provided on a front frame, a caster wheel, a caster axle and a caster bracket connected to the pivotal connecting unit. The caster bracket includes side walls supporting the caster axle, a top wall extending rearwards from the upper side of the caster wheel and interconnecting the left side wall and the right side wall, and left and right cover portions for covering gaps between the side walls and the caster wheel.

Work vehicle

A grass mower includes a blade shaft for rotating a blade within a mower deck supported to a vehicle body, a power transmission mechanism for supplying rotational power to the blade shaft, a duct for air-conveying cut grass pieces from the mower deck to the grass collecting bag and a flow boosting device incorporated in the duct. The flow boosting device increases a speed of air flow inside the duct by feeding air through a nozzle opening adjacent an inner circumferential face of the duct along a flow direction of the air flow.

A vehicle wheel includes a rim having an inner peripheral surface, and a center disc. The center disc includes a disc portion, and an arm plate portion extending radially outward from the disc portion. The arm plate portion includes an outer boundary defined by a plurality of arc outer peripheral surfaces and a plurality of concave boundary surfaces. The plurality of arc outer peripheral surfaces have a radius equal to a radius of the inner peripheral surface of the rim. The plurality of arc outer peripheral surfaces are joined to the inner peripheral surface of the rim at a weld attachment interface to produce a plurality of holes defined by the plurality of concave boundary surfaces and the inner peripheral surface of the rim.

Vehicle wheel

A work vehicle includes a vehicle frame, a rotating connection unit provided in the vehicle frame, and a caster assembly connected to the rotating connection unit. The rotating connection unit includes a housing sleeve, a swivel post, a first bearing and a second bearing supporting the swivel post to be rotatable within the housing sleeve, and a rotation stopper disposed between the swivel post and the housing sleeve to stop rotation of the swivel post. The caster assembly includes a caster wheel, and a caster bracket connected to the swivel post to rotatably support the caster wheel.

A work vehicle includes a pair of left and right steerable wheels, a pair of left and right drivable wheels, and a boss portion that supports the steerable wheel pivotally about a steering axis via a king pin. The boss portion is closer to a width center of the steerable wheel than a vehicle body inner lateral side end of the steerable wheel.

A grass cutter is provided with a mower and a duct. The mower includes a rotary blade which cuts grass by being driven to rotate, a mower deck which houses the rotary blade, and a fan which is arranged above the mower deck and generates carrier air. The duct includes a duct body which communicates with the mower deck and extends in a conveyance direction of grass clippings cut by the rotary blade, and an opening which is configured to allow carrier air generated by the fan to be introduced into the duct body.

A self-propelling work vehicle for forward and reverse drive includes a handle unit attached to the vehicle body for a first shift movement along a first direction with a neutral position and a second shift movement from the neutral position along a second direction intersecting the first direction. Forward drive speed or reverse drive speed is determined based on the first shift movement. A guide unit attached to the vehicle body includes a maximum forward speed guide member for defining a shift movement end of the handle unit determining a maximum forward speed of the forward drive speed, and a neutral guide member for guiding the second shift movement of the handle unit from the neutral position defined as a starting position. The maximum forward speed guide member and the neutral guide member are positionally adjustable independently of each other.

A work vehicle including a control device for moving an implement through a mechanism including an adjustment mechanism for locking the work implement unit with a predetermined stroke position including a rod, a cam engaging unit mounted on the rod and a cam for producing rotation with the cam engaging unit. The cam retains the work implement in a retaining position through first operational movement of the control device for moving the work implement unit from a basic position to a far side position beyond the retaining position and then returning the work implement unit to the retaining position, and allows the work implement unit to return to the basic position through a second movement control device.

A ride-on mower with a mower unit attached to a frame unit includes a headlight housing extending in a transverse direction of the vehicle body over the width of the frame unit and fixed to the frame unit forwardly of a front end of the mower deck. A right and left pair of headlight units are housed in the headlight housing. Light passage portions are formed in opposite end portions of the headlight housing for directing light coming from each of the headlight unit to the side and/or to the rear toward a direction of the front end of the mower deck.
