PROBLEM TO BE SOLVED: To solve a problem that frame constitution for supporting rear wheels is complicated because no transmission case for covering left and right rear wheel transmission shafts is provided to be left in a naked condition, in a conventional farm machine in which a travel transmission unit is provided to transmit engine torque to rear and front wheels and in which transmission from the transmission unit to the left and right rear wheels on the rear side is rotation-driven by rear wheel transmission shafts interlockedly connected via a universal joint. SOLUTION: Rear transmission cases 49, 49 are provided longitudinal- directionally to conduct transmission to the respective left and right rear wheels 3, 3 based on an output from a transmission case 14 provided in a front part of a machine body, front ends of the transmission cases 49, 49 are connected to a rear part of the transmission case 14, and arrangement therefore is constituted into a truncated chevron shape of top view to open a clearance between the left and right cases 49, 49 toward the rear end side.
