Abstract
Official abstract text for this publication.
An agricultural tractor seeks to simplify a shaft support structure in a lower portion side of an elevating hydraulic cylinder which is externally installed to a rear side of a transmission case. The agricultural tractor of the present invention is provided with a travel machine body to which an engine and the transmission case are mounted, a lift arm which is provided in a rear portion side of an upper surface of the transmission case so as to freely oscillate up and down, the elevating hydraulic cylinder which oscillates up and down the lift arm, and rear axle cases which protrude laterally outward from the transmission case. An upper portion side of the elevating hydraulic cylinder is connected to the lift arm, and a lower portion side of the elevating hydraulic cylinder is supported to the travel machine body. The lower portion side of the elevating hydraulic cylinder is axially supported rotatably via a laterally directed pivot pin shaft by a hitch portion which is integrally formed in at least one of the right and left rear axle cases so as to protrude backward, and a bracket portion which is integrally formed in a rear surface of the transmission case so as to protrude backward.
