  • Patent number: 8960805
    Abstract: A work vehicle includes a vehicle body, a seat section including a forward driver's seat and a rear seat, a rear seat posture changing mechanism for changing the rear seat in its position between a first posture where the rear seat is in a non-use condition and a second posture where the rear seat is in a use condition, a load-carrying platform disposed rearwardly of the seat section, and a partitioning member for partitioning the seat section from a space behind the seat section. The load-carrying platform includes a forward platform and a rearward platform and is switchable in its state between an extended state where a fore/aft length of the load-carrying platform is increased after the forward platform is moved forward, and a contracted state where the fore/aft length of the load-carrying platform is decreased after the forward platform is moved rearward.

  • Patent number: 8439141
    Abstract: 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.
