A riding grass mower includes a driver seatin a travel chassis, a mower decksupported by the travel chassis, a rotary bladein a glass-cutting space defined by side wall and a top plateof the mower deck, a blade motorconfigured to supply motive power to the rotary blade, and a blade motor control unitconfigured to control the blade motor. The blade motor control unitincludes a main drive control unitconfigured to rotate the rotary bladeforward, an auxiliary drive control unitconfigured to rotate the rotary bladebackward, and a drive selection unitconfigured to selectively operate the main drive control unitand the auxiliary drive control unitat a start of mowing with use of the rotary blade

A mower unit provided in a grass mower unit includes a mower deck having a top plate and a side plate extending downwards from the top plate, a rotational shaft extending through the top plate and rotatably supported to the top plate, and a blade attached to the rotational shaft inside the mower deck. A vibration detection unit is attached to the mower deck for detecting vibration in the mower deck. Vibration detected by the vibration detection unit is informed via an informing unit.

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.

A dust removal system for a riding lawn mower, comprising an engine, a speed change device disposed outside of an engine compartment, and a universal coupling inserted through an opening provided to a separating wall in order to connect an output shaft of the engine and an input shaft of the speed change device. The dust removal system is composed of a perforated board which rotates integrally with the output shaft and around the axis of the output shaft in order to impede grass cuttings from flowing into the engine compartment through the opening, the perforated board having an insertion hole formed in the center to allow the universal coupling to be inserted; and a seal unit for substantially sealing the space between the universal coupling and the peripheral edge of the insertion hole. The seal unit has a radially extending flange formed on the universal coupling, and a ring member in which one end is mounted on the flange and the other end is in contact with the peripheral area around the insertion hole.

Dust removal system for a riding lawn mower

A riding mower comprises a raising and lowering mechanism (), the raising and lowering control lever (), and a PTO mechanism () operated by a clutch lever (). When the raising and lowering mechanism () reaches a predetermined height, a operatively connecting mechanism () transmits, to the raising and lowering control lever (), a return-to-neutral displacement for returning the raising and lowering control lever () to the neutral position, and transmits, to the clutch lever (), a disengaging displacement for returning the clutch lever () to the disengage position. A first adjusting operation member () adjusts a triggering displacement at which the raising and lowering displacement is transmitted to the raising and lowering control lever () as the return-to-neutral displacement. A second adjusting operation member () adjusts a triggering displacement at which the raising and lowering displacement is transmitted to the clutch lever () as the disengaging displacement.
