Abstract
A front power take-off for tractors. A drive pinion shaft provided in a differential mechanism for driving the front wheels is positioned in the center of pivotal movements of a front axle housing a front working power out-put shaft and a front wheel drive power input shaft for driving a drive pinion are disposed so that the axes of these power shafts are under and on the right and left sides of the drive pinion shaft, and two transmission shafts disposed in right and left portions of a lower section of a transmission case connect drive mechanisms provided in said right and left portions of the lower section of the transmission case to the power shafts. The rotary power taken out from the transmission case is transmitted by the transmission shafts to their respective front power take-off portions at a high speed without these shafts vibrating. Drive gear mechanisms for rotating the front working power output shaft and front wheel drive power input shaft are provided in a drive gear case in such a manner that these drive gear mechanisms overlap each other in the longitudinal direction and are spaced far from each other in the lateral direction to allow the drive gear case to be disp…
