A work vehicle includes an engine, a particulate filter, and an oil separator. The particulate filter is connected to the engine to collect particulate matters contained in exhaust gas from the engine. The particulate filter is provided to overlap with the engine when viewed in a height direction along a height of the work vehicle. The oil separator is connected to the engine via a blow-by-gas discharge pipe to catch a liquid component in blow-by-gas from the engine. The oil separator is provided between the engine and the particulate filter to overlap with the particulate filter when viewed in the height direction.

Work vehicle

A merge and discharge unit has: a reservoir unit in which fuel can be collected; a first merge unit for merging into the reservoir unit the fuel from an upstream site upstream of the merge and discharge unit on a fuel supply route; a second merge unit for merging into the reservoir unit the fuel from a first fuel return route; a first discharge unit for discharging a portion of the fuel of the reservoir unit into a downstream site downstream of the merge and discharge unit on the fuel supply route; and a second discharge unit for discharging a remaining portion of the fuel of the reservoir unit into a second fuel return route.

Device for supplying fuel to engine

An exhaust gas purifying device is disposed in a portion of a motor section rearwardly of a vehicle body. A cylindrical mixing exhaust pipe is provided in a distal end portion of an exhaust pipe, through which exhaust gas discharged from the exhaust gas purifying device flows. The mixing exhaust pipe has a larger diameter than the exhaust pipe to overlap the exhaust pipe in a radial direction for drawing ambient air by the exhaust gas discharged from the exhaust pipe and mixing drawn air with the exhaust gas to discharge the mixed gas to the outside from a discharge opening. The mixing exhaust pipe is arranged in a lower side position of the motor section on one side of the vehicle width direction with the exhaust gas being discharged toward the front of the vehicle body.

Work vehicle having exhaust apparatus

Portion of a tractor

A speed changer lever and a lift lever are supported to a lever supporting structure that extends from the front end of an armrest disposed laterally of a driver's eat to the forward side of the vehicle body. A speed changer lever guide face portion is provided at a transversely inner portion of an upwardly oriented face of the lever supporting structure. A lift lever guide face portion is provided at a transversely outer portion of the upwardly oriented face of the ever supporting structure. The lift lever guide face portion is set at a disposing height lower than the speed changer lever guide face portion. An upper end of the lift lever is set at a disposing height lower than the upper end of the speed changer lever. A speed changer lever guide groove and a lift lever guide groove are disposed parallel to each other.

A transmission device for a work vehicle, comprising a travel drive system for transmitting engine power to a travel device; an implement drive system for transmitting engine power to an external power take-off shaft; braking operation tools for a braking operation; a stop operation mechanism provided to the travel drive system and capable of interrupting the transmission of power to the travel device; and a hydraulically operated PTO clutch for interrupting the transmission of power to the external power take-off shaft, the PTO shaft being provided to the implement drive system; wherein

Transmission device for work vehicle

A working vehicle provided with a hydraulic continuously variable transmission, has a plurality of wheels; a vehicle body supported by the plurality of wheels; a hydraulic continuously variable transmission that is supported by the vehicle body, and that has a speed change actuation shaft; a speed change pedal operatively linked to the speed change actuation shaft for controlling the speed change actuation shaft; and a neutral bias mechanism for biasing the speed change actuation shaft toward a neutral position. The bias mechanism includes a cam portion that pivots together with the speed change actuation shaft; an operation member that abuts against the cam portion; and a biasing means for biasing the operation member toward the cam portion. The biasing means is disposed above a step surface of a riding step.

Working vehicle with hydraulic continuously variable transmission

To provide a working vehicle with a simple body structure, an HST case containing a hydraulic stepless transmission is disposed between an engine adjacent one end in a fore and aft direction of a vehicle body, and a propelling transmission case disposed adjacent the other end in the fore and aft direction. The HST case, with the engine and propelling transmission case, forms the vehicle body. With this construction, a driving deck is located at a relatively low level so that the driver may board and alight from the deck with ease. Despite the low level of the deck, the bottom of the vehicle body is at a relatively high level to be free from contact with projections on unleveled terrain. Frame strength may be increased where the HST case is connected between a main clutch housing connected to the rear of the engine and the propelling transmission case.
