PROBLEM TO BE SOLVED: To prevent accumulation of litter to a reaping support base for supporting a reaper provided in a traveling gear case, a by-pass transmission case and a reaping hydraulic valve, etc., and reduce cost of a distribution part of oil to the reaping hydraulic valve, etc., and reduce cost of an attaching part of a blower. SOLUTION: A reaping hydraulic valve 8 is provided at a position apart from a gear train part of a transmission mechanism 4c of the traveling gear case 4 in a protruded space part (a) formed in the traveling gear case 4 by the reaping support base 6 for supporting the reaper provided in the upper part of the traveling gear case 4 and the by-pass transmission case 7 provided on the outside of either one side of the rear, and an oil flow passage is provided in the traveling gear case 4. The oil is shared with the traveling gear case 4, the oil of the hydraulic stepless variable gear and the oil of the reaping hydraulic valve 8.
