Abstract
An elevating apparatus for a working vehicle includes separate front lifting and rear lifting mechanisms that can be elevated by hydraulic cylinders, a feedback rod arranged between a link arm of one of the lifting mechanisms and a hydraulic pressure control apparatus for controlling the hydraulic cylinders. A change-over lever selects the front lifting mechanism or the rear lifting mechanism, and an elevating lever controls elevation of the lifting mechanisms. When one of the lifting mechanisms is selected and elevated by operation of the change-over lever, the elevating lever is operated normally without causing abutment between an adjuster member attached to the feedback rod that is interactive with the elevating lever, and an interactive member of the elevating lever. A return mechanism between the change-over lever and the elevating lever enables the elevating lever to be returned to the neutral position when selecting one of the front and rear lifting mechanisms. By suitably changing the attached position of a feedback rod with respect to a hydraulic pressure control apparatus, a change-over lever can be attached dismountably to the hydraulic pressure control apparatus, and only one of the hydraulic cylinders can be operated, or both the hydraulic cylinders can be operated alternatively.
