PURPOSE:To prevent a rotary mower from touching a front-wheel power transmission shaft in time of its lifting motion, by installing a case front-wheel power takeoff shaft of a tractor attaching the rotary mower to its web part, in the sideward of a transmission case. CONSTITUTION:A front wall part 5a formed in front of a transmission case, making up such a case cover 4 as formfitting with this wall part, and both are put together, thus a case for a front-wheel power takeoff shaft 9 is constituted. For power transmission, an output shaft 39 of a hydraulic motor 3 is formed into a spline shaft which is engaged and fitted in an inner diameter spline 8b of an output gear 8 provided with an insert output gear 8a. Like this, the output shaft 39 and the output gear shaft 8 are individually constituted apart and made up to be insertionally assembled so that the hydraulic motor comes possible to be assembled later on. A gear 10 of a counter shaft 11 engages this output gear 8a and further engages an insert output gear 9a of the front-wheel power takeoff shaft 9. |
