A work vehicle is provided with a body, a driver section and an air conditioner, and the air conditioner is supported by the body and located on a side of the body.

Work vehicle

A working vehicle includes a prime mover, a driver's seat selectively set in either a first posture where a driver can sit thereon or a second posture where the driver cannot sit thereon, a speed controller to receive power from the prime mover and perform a speed-changing of the power, a PTO shaft to receive the speed-changed power from the speed controller, a posture switch to detect whether the driver's seat is set in the first or second posture, a parking switch to detect parking of a vehicle body, and a first actuator. During driving of the prime mover, the first actuator maintains the driving of the prime mover when both the parking and the driver's seat set in the second posture are detected, and stops the driving of the prime mover when neither the parking nor the driver's seat set in the second posture is detected.

Working vehicle

A working vehicle includes a steering handle, a vehicle body to travel by manual steering via the steering handle or automatic steering for the steering handle based on a scheduled traveling line, a setting switch to switch between valid and invalid, a setting mode to set at least the automatic steering before the automatic steering is started, and a display including a driving display portion to display driving information of the vehicle body during traveling. When the setting mode is switched to be valid, the display changes a displaying state of the driving display portion to another different displaying state different from the displaying state where the setting mode is invalid.

Working vehicle having a display for displaying driving information thereof

A tractor includes: a driver seat on which a driver can sit; a hoodprovided in front of the driver seat; and an antenna unit that receives satellite positioning information. When viewed from the front, an upper end portion of a ROPS and at least part of the antenna unit overlap with each other.

Tractor and working vehicle

A link mechanism is provided between a first member and a second member to effect a bending/stretching motion in operative association with a telescopic expanding/contracting motion of the first member and the second member. A supporting mechanism is provided to support, to the link mechanism, a wire having flexibility and connected between a first device on the side of the first member and a second device on the side of the second member. The supporting mechanism fixes the wire to each link member of the link mechanism in position so that the wire is deformed while maintaining its state following a shape of the link mechanism in operative association with the bending/stretching motion of the link mechanism.

A drive device for a PTO shaft includes a parking switch to detect a parking state of a vehicle body, a permission switch constituted of a self-returning switch and connected to the parking switch, the permission switch being configured to be switched to permit driving a PTO shaft, the PTO shaft being configured to be driven by a power of a prime mover disposed on the vehicle body, and a first switch device to be switched to enable the PTO shaft to be driven when the permission switch is switched to permit driving the PTO shaft under a state where the parking switch detects the parking state of the vehicle body.

Drive device for PTO shaft of working machine

A working vehicle includes a vehicle body to travel, a steering handle to be turned to steer the vehicle body, and a steering switch to steer the vehicle body separately from the steering handle. The steering switch may be a switch to be operated in a pressing manner or in a sliding manner to steer the vehicle body. In addition, the steering switch may be arranged around the steering handle.

A work vehicle includes a frame structure between an operator-side space adjacent to the operator and a device-side space adjacent controlled devices. The control lever system for the work vehicle comprises a pivotal shaft mounted in the vicinity of a lever opening formed in the frame structure; a boss portion supported to the pivotal shaft to be rotatable about the pivotal shaft; a control lever portion radially extending from the boss portion to the operator-side space; a controlled lever portion radially extending from the boss portion to the device-side space; and a seal member for closing a gap between the boss portion and an area of the frame structure where the lever opening is formed.

Control lever system

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.

Display system for work vehicle having power take off (PTO)

A working vehicle includes an engine, a vehicle body frame on which the engine is mounted, an exhaust gas treatment device for treating exhaust gas of the engine, and a fixing base for fixing the exhaust gas treatment device, and the fixing base is separated from the engine by a gap. Furthermore, a support body for connecting the fixing base to the vehicle body frame is also separated from the engine by a gap. A bellows pipe for absorbing solid-borne sound is provided in an area where a suction pipe of the exhaust gas treatment device is connected to an exhaust manifold of the engine.

Working vehicle including exhaust gas treatment device

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.

Floor arrangement of driver's section of vehicle

An improvement in a work vehicle having an exhaust gas treatment unit is disclosed. An engine is disposed in an engine room formed in a vehicle body and supported by the vehicle body. A support unit includes right and left vertical struts mounted on the vehicle body across the engine along a vehicle body transverse direction. The exhaust gas treatment unit is disposed inside the engine room and attached to the support unit upwardly of the engine, under a posture elongate along the vehicle body transverse direction.
