Abstract: A tractor transmission includes a change speed mechanism, a shift lever (30) for shifting the change speed mechanism, a super-reduction mechanism (16) for decelerating and outputting power inputted thereto, the super-reduction mechanism having a larger reduction ratio than the change speed mechanism, and an overdrive mechanism (45) for accelerating and outputting power inputted thereto. A single switching device (29) is provided for operating both the super-reduction mechanism and overdrive mechanism. The switching device is shiftable, when the super-reduction mechanism is in neutral, from a state of operating the super-reduction mechanism to a state of operating the overdrive mechanism.

Abstract: A transmission comprising a main change speed mechanism, an auxiliary change speed mechanism, a rear differential mechanism and a cassette type supplementary change speed mechanism. The supplementary change speed mechanism acts on the transmission through an opening defined in a transmission case housing the transmission. The supplementary change speed mechanism is housed in and supported by a supplementary change speed case which is attached to the transmission case. Transmissions of various specifications may be provided by making various types of supplementary change speed mechanism. The supplementary change speed mechanism is applicable to a propelling transmission line and/or a power takeoff transmission line.

Abstract: Hydraulic control system including a bypass provided in an intermediate portion of an oil passage extending from a position control valve to a hydraulic actuator for raising and lowering a working implement. A draft control valve disposed in the bypass controls the pressure of oil flowing into the bypass, in response to the displacement of a member for sensing the draft force of the working implement.
