Abstract: A work vehicle includes a vehicle body, an occupants' section provided in the vehicle body and having a driver's seat and a passenger's seat and a storage space that is provided under seats and opened upwards, the storage space having a first storage space section disposed under the driver's seat and a second storage space section disposed under the passenger's seat. The seats are supported to be pivotable about an axis extending along the width direction of the vehicle body and access to the first storage space section and the second storage space section is made possible by upwardly pivoting these seats. The driver's seat is slidable along the front-rear direction of the vehicle body. The first storage space section has a front-rear length shorter than the front-rear length of the second storage space section.

Abstract: A floor arrangement of a driver's section of a vehicle includes a floor frame, an acoustic absorbent placed on the floor frame and a floor mat placed on the acoustic absorbent. A wire harness is placed in an acoustic absorbent-free space formed between the floor frame and the floor mat. A protector is provided inside the acoustic absorbent-free space in the vicinity of the wire harness and extends upward from the floor frame. This protector is affixed to the floor frame and configured to receive a load applied to the floor harness from the upper side thereof.

Abstract: A display system for a work vehicle includes a rotation speed display section for selectively displaying an engine rotation speed or a PTO rotation speed in a same display area, a display selection switch for outputting a display selection command, a discrimination display section for displaying a discrimination object for discriminating which of the engine rotation speed and the PTO rotation speed is being displayed and a display control section for selectively providing an engine rotation speed display signal or a PTO rotation speed display signal to the rotation speed display section based on the display selection command and providing the discrimination display section with a display signal for the discrimination object based on the display selection command.

Abstract: A work vehicle has a ground-work unit that is mounted under a frame supported by front wheels and rear wheels and disposed forwardly of the front wheels. The work vehicle includes a steering wheel supported to a steering post and consisting of spokes and a ring. A man-machine interface face formed in the steering post downwardly of the steering wheel and around a rotational axis of the steering wheel includes a display face having a flat panel display and an operation face having an operation input device. The steering wheel is greater in size than the flat panel display as seen in the direction of rotational axis of the steering wheel, and the operation face is greater in length than the flat panel display in the direction of vehicle width.

Abstract: An engine in which an oil consumption and a leakage of blow-by gas can be stably reduced for a long period of time. The engine includes a first land (3), a first ring groove (4), a second land (5), a second ring groove (6), a third land (7), a third ring groove (8), and a piston skirt (9) formed on a piston peripheral wall (1) in the above-recited order from a side of a piston head (2). A first pressure ring (10) is fitted in the first ring groove (4). A second pressure ring (11) is fitted in the second ring groove (6), an oil ring (12) fitted in the third ring groove (8), and an indentation (13) is formed at the second land (5).

Abstract: A provided powder/granular material feeding device fully satisfies the function of sufficiently preventing bridges and ratholes and the function of favorably stabilizing the filling rate of an outlet portion. Moreover, the powder/granular material feeding device does not require consumable items such as a flexible chute or leave a large amount of powder/granular material in a specific region inside a chute. The powder/granular material feeding device includes: a hopper 1 that receives powder/granular material; an outlet portion 2 that discharges powder/granular material; a chute 3 that guides, into the outlet portion 2, powder/granular material dropped from the hopper 1; and a stirring part 4 that rotates stirring members 4b about a shaft 4a protruding so as to tilt diagonally upward from the lower part of the interior of the chute 3.

Abstract: A work machine, comprising: a diesel engine; a gas emission cleaning device having a filter for trapping particulate matter included in gas emissions emitted from the diesel engine; and filter regenerating means for performing automatic regeneration to automatically combust and eliminate particulate manner that has accumulated in the gas emission cleaning device, when the accumulated amount of the particulate matter has exceeded a predetermined value; wherein the filter regenerating means has automatic-regeneration-allowing means for allowing the automatic regeneration to be carried out by an external command; and, at startup, the automatic-regeneration-allowing means disallows carrying out automatic regeneration.

Abstract: A cabin for a work vehicle comprises: a driver's seat positioned within the cabin; cabin frames including at least a transverse frame located in a rear region of the cabin; a roof supported by at least some of the cabin frames; at least one air-conditioning duct located within the roof; an air-conditioning unit located rearwardly with respect to a rearward end of a seat portion of the driver's seat and adjacent the transverse frame for conditioning air and for feeding air-conditioned air into the at least one air-conditioning duct.

Abstract: A mower unit configured to be supported to a work vehicle at a position between front wheels and rear wheels, comprises a mower deck; at least one blade supported by the mower deck; a climb-up assist member in which an inclined surface is formed for assisting the wheels in climbing over the mower unit; and a connecting device for detachably connecting the climb-up assist member to the mower unit in a service position in which the inclined surface assists the wheels in climbing over the mower unit.

Abstract: The hydraulic suspension system comprises a suspension mechanism (100) for a traveling vehicle body, a suspension reference position variation mechanism (18) for varying a reference position of a suspension stroke of the suspension mechanism, and a stopped state detector (58) for detecting a state in which operation of the suspension mechanism (100) has stopped. The control management unit (60) controls the suspension reference position variation mechanism (18) so that when operation of the suspension mechanism (100) is detected by the stopped state detector (58) to be in a stopped state, the operation of the suspension mechanism (100) moves toward a target range, in preference to control based on a suspension stroke position obtained from a suspension stroke position sensor (37).

Abstract: A mounting arrangement for mounting a cooler unit to a work machine has a traveling device, a machine body frame, an engine and the cooler unit disposed adjacent the engine. The arrangement includes a support deck provided in the machine body frame for supporting the cooler unit, an attachment unit for releasably fixing the cooler unit to the machine body frame and a movement mechanism provided between the cooler unit and the support deck, the movement mechanism allowing the cooler unit to effect a translational movement to change a distance relative to the engine.
