Abstract

PURPOSE:To eliminate the need to individually control two clutches, to simplify control, and to simplify constitution by a method wherein a slide gear engaged with a gear through slide control is located on a transmission shaft. CONSTITUTION:A gear 2 positioned right after a front bearing 14 is secured on an input shaft 1, and a gear 4 having the same as that of the gear 2 is rotatably situated on the rear side of the gear 2 on the input shaft 1. A transmission shaft 5 to transmit a power to a power take-out shaft in the rear is supported to a bearing 17, and a slide gear 6 geared with the gear 2 or the gear 4 through slide control and performing spline-transmission to the transmission shaft 5 is situated to the front of the transmission shaft 5.

虞れがある。Conventional technology and problems to be solved by the invention A ground speed is provided that is transmitted through a variable speed transmission mechanism that changes the vehicle speed, and a motor speed that is transmitted at a constant speed regardless of this variable speed transmission mechanism. In a power take-off transmission device for a tractor, a clutch is usually provided in the transmission mechanism that transmits power from the speed change transmission mechanism to the power take-off shaft, and a clutch is provided in the transmission mechanism that connects and disconnects power to the power take-off shaft. A clutch is installed in the transmission mechanism that transmits the power from Because it is necessary to operate the clutches to the disengaged side, operating each of these separately is time-consuming and cumbersome, and is likely to result in erroneous operation. Providing an interlocking mechanism in which the front side is on the incisal side may require a large number of members and the structure may become complicated.
