A work vehicle includes a detection signal processing section for processing detection signals from a group of sensors mounted on a vehicle body and outputting detection result data and a display unit for displaying the detection result data. The display unit includes a first displaying area for displaying time changing data included in the detection result data, the time changing data changing over time, a second displaying area for displaying safety data included in the detection result data, the safety data relating to safety confirmation, and a third displaying area for displaying alarm-relating data included in the detection result data.

A work vehicle includes an engine controller for driving an engine, a power supply line, a power supply control line, and a display signal line. When a check switch switchable into a safe position corresponding to safe drive of the engine and a non-safe position is switched to the safe position, the power supply control line renders a power supply relay ON. The display signal line transmits a signal indicative of the switched state of the check switch to a display.

A utility vehicle includes a cargo box and a seat device located on the front side of the cargo box. The seat device includes a seat bottom and a seat back that includes a first lateral swinging shaft that extends in a lateral direction, a seat back frame that swings about the first lateral swinging shaft between an upright position and a horizontal position at which the seat back frame overlaps with the seat bottom, and a seat back main body that is attached to the seat back frame. The seat back frame in the horizontal position defines an expansion floor by which the floor of the cargo box is expanded in a forward direction. The seat back main body swings to a hanging orientation with respect to the seat back frame in the horizontal position and is located in front of the seat bottom.

Utility vehicle

A traveling work vehicle includes: a vehicle speed control portion configured to control the vehicle speed; a number-of-revolutions calculation portion configured to calculate, as an actual number of revolutions, a number of revolutions of a single rotary power source per unit time; a number-of-revolutions command generation portion configured to generate a number-of-revolutions command using a requested number of revolutions; a requested vehicle speed input portion configured to input a requested vehicle speed that is based on a user operation; a requested vehicle speed calculation portion configured to calculate a computed requested vehicle speed using a deviation between the requested number of revolutions and the actual number of revolutions, and the requested vehicle speed; and a vehicle speed command generation portion configured to give the vehicle speed control portion a vehicle speed command that is generated using the computed requested vehicle speed.

Traveling work vehicle equipped with work apparatus

A work vehicle having an implement includes an engine control unit for controlling an engine and detecting an abnormal state of the engine, a PTO transmission mechanism for transmitting power from the engine to the implement, a PTO clutch for switching ON/OFF power transmission by the PTO transmission mechanism and a clutch control circuit configured to render the PTO clutch OFF based on a detection signal outputted by the engine control unit at time of detection of the abnormal state.

A discharge shroud device includes a cover element extending outward from a side of a mower deck for covering a discharge opening defined at the side of the mower deck, a shroud support unit for attaching the cover element to the mower deck, a blocking plate provided in the cover element to be swingable between an open position in which the discharge opening is opened and a closed position in which the discharge opening is closed, and an open-position fixing element for fixing the blocking plate to the cover element at the open position.

Discharge shroud device for mower deck

A work vehicle includes: a traveling apparatus and a work apparatus that use rotational power from a power source configured to output rotational power by consuming fuel; a display unit having a changing data display region; a working state detection portion configured to detect a working state in which the work apparatus is being driven; an instantaneous fuel economy calculation portion configured to calculate, as instantaneous fuel economy, fuel consumption per time in the working state; and a display data generation portion configured to generate instantaneous fuel economy display data for displaying the instantaneous fuel economy in the changing data display region.

A steering lever system includes a pair of lever bodies, a pivotal body coupled to each of the lever bodies and a neutral position detector. The pivotal body includes a first boss portion and a second boss portion. The lever body is pivotable about a first pivot axis of the first boss portion from a neutral position to a neutral end position. The lever body is also pivotable about a second pivot axis of the second boss portion from a forward traveling end position through a neutral position to a reverse traveling end position. The neutral position detector is responsive to a detected portion provided in an auxiliary member fixed to the lever body, at the neutral end position of the lever body. The detected portion is offset from a pivotal locus of the lever body about the first pivot axis.

A work vehicle includes a vehicle body frame supported on a ground surface by wheels, a reinforcing plate provided in the vehicle body frame, an oil equipment using oil, and a drain pan configured to receive and discharge the oil discharged from the oil equipment. The reinforcing plate defines a drain hole extending vertically therethrough. A tilted face is provided in a face of the reinforcing plate. The tilted face extends with a downward inclination from a dropping point on the reinforcing plate for the oil discharged from the drain pan to the drain hole.

A fuel system for a work vehicle including a fuel tank comprising a main tank body and an auxiliary tank body, a canister, and a fuel-gas introducing passage for connecting a top portion of the auxiliary tank body to the canister. The top portion of the auxiliary tank body is located higher than the main tank body when the fuel tank is installed on the work vehicle. A fuel filling pipe extends through the top portion of the auxiliary tank body and has a first end arranged outside the auxiliary tank body and a second end arranged within the auxiliary tank body.

Work vehicle with engine mounted rearwardly

A riding mower includes a mower body frame extending in front-and-rear directions between a pair of left and right rear wheels, a horizontal installation surface defined in an area near the rear wheels, an engine arranged on the installation surface, rearward of axle(s) of the rear wheels, an operator's seat arranged forward of the engine, and a fuel tank. The fuel tank includes a front tank portion extending in the front-and-rear directions below the operator's seat, and a rear tank portion connected with the front tank portion, extending in mower body front-and-rear directions on one side of the engine in mower body transverse directions, and extending higher than the front tank portion.

Riding type mower

A work vehicle includes a vehicle frame extending between a right and left pair of rear wheels. An engine is mounted in a vertical position on a horizontal mounting surface defined in the vehicle frame in a peripheral area of the rear wheels in a central portion of a transverse direction of the vehicle. A fuel tank includes a main tank body mounted under a driver's seat and an auxiliary tank body mounted on the mounting surface on one lateral side of the engine in the transverse direction of the vehicle. A canister is mounted adjacent to the engine on one lateral side of the engine and rearwardly of and adjacent to the auxiliary fuel tank.
