Abstract:
1. A power take-off assembly of a working vehicle, comprising: an output sleeve disposed longitudinally of the vehicle in an end portion of the vehicle; a low speed gear freely rotatably provided around said output sleeve; a high speed gear freely rotatably provided around said output sleeve, said high speed gear being greater in rotary speed than said low speed gear; a shifter collar disposed around said output sleeve between said high and low speed gears so as to selectively engage one of said high and low speed gears with said output sleeve; a PTO shaft having two opposite splined ends, the numbers of teeth of said splined ends being different from each other, wherein said PTO shaft is selectively reversibly inserted at one of said splined ends thereof into said output sleeve, connected to said output sleeve, and extended at the other splined end thereof outward from said end portion of the vehicle; a second collar disposed around inner end portion of said output sleeve, said second collar connected to said shifter collar so as to slide integrally with said shifter collar on said output sleeve; and an actuator for restraining the sliding of said second collar on said output sleeve, wherein said actuator is actuated by an end surface of said PTO shaft so as to hold said second collar at a position where said low speed gear engages with said output sleeve when one said splined end that is greater in number of teeth than the other splined end is inserted into said output sleeve.
