Abstract: A power transmitting apparatus comprises a housing having an opening at its end surface in the longitudinal direction thereof to be closed by a cover member (33), which supports an end of a brake support shaft (60) rotatably supporting a brake shoe (61). A hydraulic cylinder (63) for operation the brake is detachably attached to a side wall of the housing. A piston (64) of the hydraulic cylinder contacts with a free end of the brake shoe. The cover member also supports ends of a clutch shaft (26) and a PTO shaft (29), while a clutch housing (38) of a PTO clutch (27) is provided on the clutch shaft so as to be braked by the brake shoe in the state of the PTO clutch disengaged, thereby constituting a subassembly. By attaching the cover member to the end surface of the housing so as to close the opening, all the brake support shaft, the clutch shaft and the PTO shaft supported by the cover member are installed in the housing.

Abstract: A reversible PTO shaft having opposite splined ends whose numbers of teeth are different from each other is inserted at one of the splined ends into an output sleeve and not-relatively rotatably connected to the output sleeve. For constituting at a position out of the PTO transmission system an actuator for changing the rotary speed of the output sleeve and holding the output sleeve changed in rotary speed simultaneously to the reversing of PTO shaft, a second collar connected to a shifter collar for changing the rotary speed of output sleeve so as to be slidable integrally with the shifter collar is disposed on an inner end of the output sleeve. When the splined end of PTO shaft having the greater number of teeth is inserted into the output sleeve, a sensor having a cam surface is moved by an end surface of the PTO shaft so as to make a pin project from the output sleeve, thereby holding the second collar at its low speed position.
