A working vehicle includes a suspension including a damper to suppress vertical motion of a cabin over a vehicle body, and a restrictor to restrict the cabin at an upper limit position and/or a lower limit position. The restrictor includes a first stopper fixed to the vehicle body, and a second stopper fixed to the cabin. At least one of the first stopper or the second stopper includes a first cushion portion, and a second cushion portion softer than the first cushion portion. The first cushion portion and the second cushion portion are adjacent to each other in a direction intersecting a vertical direction, and the second cushion portion is contactable with a target of contact before the first cushion portion.

Working vehicle

A driver's seat of a work vehicle comprising a seatback section, and a seating section including a receiving surface portion formed in an intermediate portion of the seating section for receiving buttocks of the operator, and a recessed groove formed along a side frame portion at a boundary between the side frame portion and the receiving surface portion to open at an extension distal end of the seating section. The recessed groove has a bottom surface inclined downwardly from a back end of the seatback section to the extension distal end of the seating section.

Portion of a tractor

An instrument panel to be mounted at a driver's section of a working vehicle such as a tractor is secured to a frame member which extends upwardly from a main frame. A panel cover for covering a steering-wheel peripheral section of the machine includes an opening through which the instrument panel is exposed to the outside and this panel cover is detachably attached to the frame member.

Working vehicle having detachable panel cover

A damping support apparatus for fixing an onboard structure such as a framework ( H) of a cab ( ) to a vehicle body ( ). The apparatus includes support brackets attached to the vehicle body ( ), cushion couplings ( ) each disposed between the onboard structure and one of the support brackets, and dynamic dampers ( ) each attached to one of the support brackets and adjacent one of the cushion couplings. Each of the dynamic dampers ( ) includes a cylindrical holder ( ), mounting brackets ( ) formed on the holder and having connecting portions for connection to the support bracket, a bar-shaped dampermass ( ) mounted in the holder so as to form a gap ( ) with an inner peripheral surface ( A) of the holder, and elastomers ( ) disposed in at least part of the gap.
