摘要： A work vehicle includes: a muffler which flows exhaust from an engine and extends in a transverse direction so as to allow the exhaust from the engine to flow in the transverse direction; and a CVT case for covering a belt-type CVT positioned frontward of the muffler in a longitudinal direction. The CVT case includes a cooling structure for introducing cooling air from outside, cooling the belt-type CVT, and discharging the cooling air from a discharge part. An exhaust duct includes an inflow opening to be connected to the discharge part for allowing the cooling air to flow into the exhaust duct, and an exhaust opening for allowing the cooling air to flow out rearward. The exhaust opening is elongated in an extending direction of the muffler and oriented in a direction that allows the cooling air flowing out to hit the muffler.

摘要： A work vehicle includes a hydraulic stepless speed changing apparatus and a gear type speed changing apparatus operable to receive output from the hydraulic stepless speed changing apparatus to convert it into a plurality of stages of speed. A return oil passage connected to a high-pressure side circuit of the hydraulic stepless speed changing apparatus is connected to a hydraulic tank. The return oil passage incorporates an unload valve and a throttle valve, between which an operably coupling mechanism is provided. This operably coupling mechanism switches over the unload valve to an unload condition in response to an operational displacement of a brake operating member for operating a brake to its braking side.

摘要： Disclosed is a mower with a mower deck, a plurality of cutting chambers mutually communicated and arranged in a lateral direction within the mower deck, and a blade mounted in each cutting chamber to be rotatable about a vertical axis. A grass clippings guide in form of a vertical wall is disposed in an upper area within the cutting chamber, to guide the grass clippings flowing within the cutting chamber toward a center of rotation of the blade. A shield member is disposed for preventing entry of grass clippings between the grass clippings guide and a peripheral wall of the cutting chamber.
