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. In such a work-machine-lever-support structure a view from an operation room of a vehicle is ensured, the work machine lever can be easily operated, a space for getting on and off the vehicle is sufficiently obtained, and an operator can get on and off the vehicle without moving by mistake the operating lever.
A work-machine-lever-support structure for a work vehicle, wherein a work machine lever 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, said work machine lever having an arm and a lever-operating portion at a free end portion of said arm, and a base end portion of said arm being positioned at a side portion of an upper end portion of said steering-wheel-support box and being supported and fixed so as to be pivotally rotatable between at least two positions including an operating position on a side of said steering wheel and a non-operating position in front of said steering wheel, about said base end portion.
A work-machine-lever-support structure for a work vehicle, wherein a work machine lever 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, said free end portion of said work machine lever having a lever-operating portion, and said lever-operating portion being supported and fixed so as to be pivotally rotatable between at least two positions, including an operating position on a side of said steering wheel and a non-operating position in front of said steering wheel, about said base end portion of said steering-wheel-support box as a pivot, and said structure further including a safety switch for outputting a signal for prohibiting an activation of said work machine when said work machine lever pivotally rotates to said non-operating position.
