Abstract: A work machine lever for a work vehicle comprises a base end portion supported in a steering-wheel-support box and a free end portion disposed on a side of a steering wheel. The free end portion is provided with a lever-operating portion, which can be pivotally rotated between at least two positions, i.e., an operating position on the side of the steering wheel and a non-operating position in front of the steering wheel about a support base end portion of the steering-wheel-support box as a pivot and can be fixed at the respective rotation positions. Therefore, when the operator gets on and off the vehicle, the work machine lever is rotated to be fixed at a forward lever non-operating position to form a large passage space on a side of the steering wheel.

Abstract: A cabin is movable along the outer side surfaces of an operator cab floor by a vertical drive means. Specifically, pinions fixed to left and right end portions of a shaft are driven and rotated by motors installed on the operator cab floor. Rack gears engaged with the pinions are fixed to the cabin. Even when the cabin is moved and situated at its lowermost position, where the lower edges of the cabin project downwards below the operator cab floor, by the rack gears by rotations of the pinions, a single door which is continuous in the vertical direction can be installed on a side plate. Therefore, even when the whole height of the cabin is lowered to its limit, the door can be opened and closed without troubles. The shaft also functions to synchronize the rotations of the left and right pinions mechanically, thereby preventing torsion of the cabin.

Abstract: Provided with a wheeled road surface cutter comprising a front section attached thereto with steerable front wheels on both sides thereof, a rear section attached thereto with rear wheels, a pivot joint for coupling the front end of the rear section to the rear end of the front section, and a cutting device attached to the rear section on one side and substantially aligned with one of the front wheels on the same side.
