Abstract: The invention aims at providing a work vehicle in which an operator can easily view each of switches in spite of the work vehicle in which a plurality of switches such as a DPF regeneration switch, a working switch and a one-touch automatic switch are concentrically provided on a front surface of a control seat. In a work vehicle having a cabin which is inward provided with a control seat installed in a travel machine body, a DPF regeneration switch, a working switch, and a one-touch automatic switch are provided. The DPF regeneration switch is provided on an upper surface of a steering column in a base portion of a control steering wheel, and the DPF regeneration switch is arranged in a field of vision of an operator under a straight moving work posture.

Abstract: It is an object to secure a state where an operator easily reaches various operating means with a hand, and to reliably maintain an original function of an arm rest (to put the hand on the arm for rest). A working vehicle is configured such that speed of power from an engine provided in a traveling machine body is changed by a hydraulic continuously variable transmission, and the power is transmitted to a traveling unit and a working unit. An arm rest on which the operator's arm and hand are put is placed on a side of a cockpit in the traveling machine body. A main transmission lever which changes traveling speed by the traveling unit is arranged on a front end of the arm rest on the side of the cockpit. An elevating dial which hoists and lowers the working unit is arranged on a side surface of the arm rest on the opposite side from the cockpit.

Abstract: The purpose of the invention is to enable a crawler tractor to brake and stop certainly without applying a load to an engine and a driving mechanism, and without complicated operation. An operation link links a conic linkage (53) which links a steering wheel (7) with a main speed change lever (55) of the crawler tractor, and with an operation mechanism of a brake pedal (54). A neutral return mechanism for the operation link is provided. The operation link neutral return mechanism comprises a hook-like cam lever (61). When the brake pedal is depressed, the main speed change lever is moved to its neutral position before braking force occurs, and then, the brake is actuated. Accordingly, engine brake is used effectively, and the brake can be miniaturized.
