A work vehicle includes: a vehicle body that travels; a boom attached to the vehicle body to be vertically swingable; a work tool mounted to a front portion of the boom; a first illumination lamp that is disposed in the vehicle body and emits an illumination light forward; a second illumination lamp that is disposed in the boom and emits an illumination light toward the work tool; and an illumination controller that controls the first illumination lamp and the second illumination lamp, the illumination controller executing a lighting restriction of automatically turning off or dimming the first illumination lamp while the second illumination lamp is turned on.

Work vehicle

A work apparatus to be mounted to a work vehicle includes: a pair of cylindrical mastsdisposed erect on right and left sides of a vehicle body having a control valve; a boompivotally supported to the masts; an implement pivotally supported to the boom; a boom cylinderfor pivoting the boom; an implement cylinderfor operating the implement; a boom piping system communicating the control valve with the boom cylinder; and an implement piping system communicating the control valve with the implement cylinder; wherein a channel constituting memberconstituting the boom piping system extends vertically within each mast; one end of the channel constituting memberextends to the outside at a lower portion of the mast to be connected with the control valve; and the other end of the channel constituting memberextends to the outside at an upper portion of the mastto be connected with boom cylinder

Loader work apparatus

A tractor with a backhoe is disclosed. The backhoe is mounted to a rear portion of the tractor. The backhoe has a boom, an arm pivotally supported to a leading end of the boom, a bucket pivotally supported to a leading end of the arm, a boom cylinder for operating the boom, an arm cylinder for operating the arm and a bucket cylinder for operating the bucket. The tractor includes a frame attached to a rear portion of the tractor, a swing bracket supported to a rear portion of the frame to be pivotable about a vertical axis, a control valve unit having control valves for controlling the boom cylinder, the arm cylinder and the bucket cylinder and a hose unit for feeding pressure oil from the control valve unit to the boom cylinder, the arm cylinder and the bucket cylinder. The wing bracket includes a first opening open to the front side and a second opening open to the rear side. The control valve unit is disposed, in its plan view, on an extension line of the first opening and the second opening. The hose unit extends substantially linearly from the control valve unit through the first opening to the second opening.

Tractor with backhoe

A work vehicle with a working implement, comprising: a control leverfor controlling the working implementthe control lever being rockably disposed laterally of a driver's seatmounted on a vehicle bodya control valvedisposed laterally of the vehicle body for controlling actuatorsthat drive the working implement; and interlocking linksfor interlocking the control lever and spoolsof the control valveand transmitting rocking of the control lever to the spools; wherein the control leverand the spoolsare staggered transversely and longitudinally of the vehicle bodyand the interlocking linksare bent, one end of each interlocking link being connected to a first link connectorconnected to the control lever, the other end of each interlocking link being connected to a second link connector connected to one of the spools.

Work vehicle with staggered control level

A work vehicle includes a pair of, right and left booms detachably attached to a vehicle body, an implement attached to leading ends of the booms and a stand for supporting the booms with the implement being placed on a ground surface when the booms are detached from the vehicle body. The stand includes a pair of, right and left stand members provided in correspondence with the right and left booms and a stand connecting member for interconnecting the stand members. Each stand member is attached to the boom corresponding thereto in such a manner that the stand is movable between a use position in which each stand member projects downwardly from the boom for supporting the boom and a non-use position in which each stand member extends along the boom.
