An agricultural tractor (1) of the present invention aims at simplifying a shaft support structure in a lower portion side of an elevating hydraulic cylinder (29) which is externally installed to a rear side of a transmission case (17). The agricultural tractor (1) of the present invention is provided with a travel machine body (2) to which an engine (5) and the transmission case (17)are mounted, a lift arm (30) which is provided in a rear portion side of an upper surface of the transmission case (17) so as to freely oscillate up and down, the elevating hydraulic cylinder (29) which oscillates up and down the lift arm (30), and rear axle cases (18) which protrude laterally outward from the transmission case (17). An upper portion side of the elevating hydraulic cylinder (29) is connected to the lift arm (30), and a lower portion side of the elevating hydraulic cylinder (29) is supported to the travel machine body (2). The lower portion side of the elevating hydraulic cylinder (29) is axially supported rotatably via a laterally directed pivot pin shaft (32) by a hitch portion (18a) which is integrally formed in at least one of the right and left rear axle cases (18) so as to protrude backward, and a bracket portion (17a) which is integrally formed in a rear surface of the transmission case (17) so as to protrude backward.
