In a riding-type mower, a vehicle body includes a rear portion in which a pair of right/left vehicle body frames extend in a front-rear direction relative to the vehicle body, with a gap therebetween in a lateral width direction. A mowing device is configured to discharge mown grass rearward relative to the vehicle body such that the mown grass falls onto the ground. A cover is provided in a bottom portion of the vehicle body, at a position that is rearward of the mowing device, and covers a gap between the pair of right/left vehicle body frames.

Riding-type mower

A mower includes: a driver's seat provided to a vehicle frame. A transmission is arranged at least partially below the driver's seat. An engine arranged rearward of the transmission such that a bottom end of the engine is positioned higher than a bottom end of the transmission. An exhaust gas purification device is arranged rearward of the engine. An air cleaner is arranged forward of the exhaust gas purification device and above the engine. A radiator extends from an area between the transmission and the engine so as to project further upward than the air cleaner through an area between the driver's seat and the air cleaner.

Mower with improved exhaust gas component cooling

The grass mower includes a front wheel unit having a left front wheel and a right front wheel which are mounted to a vehicle body frame, a rear wheel unit having a left rear wheel and a right rear wheel which are mounted to the vehicle body frame and a mower unit disposed between the front wheel unit and the rear wheel unit downwardly of the vehicle body frame, the mower unit including a rotary blade unit that has at least a left blade and a right blade which are disposed side by side in a vehicle body left/right direction. The rotary blade unit is configured such that a tread-on track of the left front wheel is overlapped with a rotation locus portion of the left blade from the front side to the rear side thereof and a tread-on track of the right front wheel is overlapped with a rotation locus portion of the right blade from the front side to the rear side thereof.

Grass mower

A work vehicle in which a cooling fan is arranged forward of an engine and an exhaust gas purification device is arranged rearward of the engine. An inlet-side exhaust passage connects an exhaust manifold and the exhaust gas purification device. An outlet-side exhaust passage connects the exhaust gas purification device and the exhaust end portion. A first exhaust passage is coupled to the exhaust gas purification device and passes over the exhaust gas purification device to reach beside a first end portion. A second exhaust passage is coupled to the first exhaust passage and extends in a transverse direction and below the exhaust gas purification device.

Work vehicle with improved exhaust component cooling

A ride-on lawn mower includes a traveling vehicle body including an operator's seat, and a wheel post for supporting a steering wheel mounted forward of the operator's seat. The lawn mower further includes a mower apparatus connected to a front part of the traveling vehicle body, a roll-over protective structure mounted in a rear part of the operator's seat, and a front guard extending upward from the wheel post and forward of the steering wheel.

Ride-on lawn mower

A work vehicle includes a fixed hood covering a rear area of an engine compartment housing an engine and an engine accessory, a swing axis extending through the rear area of the engine compartment in a transverse direction of the vehicle, and a swing hood swinging around the swing axis between a closed position and an open position. The swing hood tucks the fixed hood inside the swing hood and thus covers the fixed hood in the open position, and covers a front area and a middle area of the engine compartment and overlaps with a front end portion of the fixed hood in the closed position.

Work vehicle

A work vehicle includes a cooling fan, an engine, and a diesel particulate filter (DPF) purifying exhaust gas of the engine, placed under a hood in that order, beginning at the front. Exhaust gas from the engine is exhausted through an exhaust passage after passing through the DPF. The cooling fan supplies cooling air to the rear. The DPF is placed such that a length direction thereof follows a width direction of a vehicle body. The exhaust passage includes a first passage, a second passage, and a third passage. The first passage extends forward and upward from the DPF before extending along the length direction thereof on a front side of the DPF. The second passage extends downward from a downstream portion of the first passage. The third passage extends to the rear from a downstream portion of the second passage and also includes an exhaust outlet.

Work vehicle with diesel particulate filter

A riding mower includes a pair of right and left front wheels; a pair of right and left rear wheels; a driver's seat provided between the rear wheels and the front wheels; an engine provided in the rear of the driver's seat; and a mower provided under the driver's seat. The riding mower is capable of being mounted with a fuel gas cylinder sideways on a side of the engine in which an operation section of the fuel gas cylinder faces backward. The riding mower further includes a guard member that is opposed to a rear surface of the fuel gas cylinder and is switchable between a protection position to cover the rear side of the operation section and an open position to open the rear surface of the fuel gas cylinder.

Riding mower

Disclosed is a fuel system for a traveling vehicle having an engine mounted on a vehicle body and a ROPS extending upward from the vehicle body. The fuel system includes a fuel tank accommodating an amount of fuel, a canister, an evaporating hose including a first evaporating hose portion and a second evaporating hose portion for sending fuel vapor generated inside the fuel tank to the canister. The first evaporating hose portion is connected to the fuel tank and extending upward from the fuel tank along a vertical post of the ROPS. The second evaporating hose portion extends downward along a vertical post of the ROPS and is connected to the canister.

Fuel system for traveling vehicle

A riding type mower comprises: a plurality of wheels; a vehicle body supported by the plurality of wheels; a water-cooled engine located in a rear region of the vehicle body; a hood for covering the engine; a driver's seat located forwardly of the hood; a rollover protection frame located between the driver's seat and the water-cooled engine, the rollover protection frame having a pair of right and left support columns spaced apart from each other in a lateral direction; a radiator for the water-cooled engine located between the pair of the support columns of the rollover protection frame.

Radiator support structure

A riding lawn mower vehicle having a riding traveling vehicle body and a mower operatively connected via a lifting/lowering link mechanism to the vehicle body to be lifted and lowered relative thereto, the mower vehicle comprising: a pair of right and left hand-operated traveling control members; a lifting control pedal having a lifting stepping face and configured to cause the mower to be lifted; a lowering control pedal having a lowering stepping face and configured to cause the mower to be lowered; and the lifting stepping face and the lowering stepping face being located laterally to each other on a floor of a driving section of the riding traveling vehicle body.
