摘要： A lawn mower has driving front wheels and driving rear wheels. The mower includes a mower unit mounted between the front wheels and the rear wheels to be vertically movable, an engine mounted to a front portion of a vehicle body, a transmission case disposed rearwardly of the engine, an HST coupled to a rear wall of the transmission case, the HST having a pump shaft and a motor shaft both projecting forwardly, a charge pump for the HST attached to a front wall of the transmission case, a transmission mechanism disposed inside the transmission case. The transmission mechanism includes an input shaft operably coupling a transmission shaft from the engine to the pump shaft, a first output shaft for transmitting power from the motor shaft to a transmission shaft for the front wheels, a PTO shaft for transmitting power from the input shaft to a transmission shaft for the mower unit, and a second output shaft for transmitting power from the input shaft to the charge pump. The first and second output shafts extend in a fore-and-aft direction of the mower and parallel with the input shaft, the second output shaft being disposed upwardly of the input shaft, the first output shaft being disposed downwardly of the input shaft.

摘要： An engine hood construction for a work vehicle is disclosed. The engine hood is vertically separatable into a lower hood section and an upper hood section. The lower hood section is fixedly attachable to and detachable from a vehicle frame, and the upper hood section is attached to the vehicle frame to be pivotably and vertically opened and closed relative to the frame. A control panel is provided at a rear portion of the engine hood and forming a rear wall of an engine room. The control panel has a forwardly opened hook shape in a plan view. The construction further includes a connecting arrangement for fixedly connecting the lower hood section to the vehicle frame and engaging members for enabling the lower hood section to be engaged with the control panel along a fore-and-aft direction of the vehicle when the connecting arrangement is not connected.

摘要： A four-wheel drive work vehicle includes an engine, a pair of right and left steerable wheels rotatably driven by receiving power from the engine via a differential mechanism, a pair of right and left non-steerable wheels rotatably driven by receiving power from the engine via right and left side clutches and a pivotal cam mechanism for operating a clutch operating member for controlling the side clutch based on a steered displacement of the steerable wheels. The pivotal cam mechanism includes a cam member which is displaced based on the steered displacement and a cam follower member operably associated with the cam member. The clutch operating member is displaced via the pivotal cam mechanism by a predetermined amount in response to a steering operation of the steerable wheels by an angle exceeding a predetermined angle from a straight traveling condition and in association with the displacement of the clutch operating member by the predetermined amount, one side clutch for one of the non-steerable wheels located on the inner side of the vehicle turn is automatically disengaged against an engaging urging force.
