Abstract
A power take-off (PTO) connection mechanism for mid mounted tools of a utility vehicle includes three main assembly members: a frame attachment mechanism, a vertical moving frame (or cradle), and a PTO assembly. The frame attachment mechanism is fixed to the frame of the vehicle or tractor. The PTO connection mechanism helps in easy and quick connection of the PTO shaft to a variety of tools with the tractor. The PTO shaft remains in continuous contact with the tool power input once it is moved in an engaged position.
Claims11
A power take-off (PTO) connection mechanism for mid mounted tools of a utility vehicle, said PTO connection mechanism comprising:
- a power take-off (PTO) assembly connected to a movable cradle;
- a PTO frame configured to receive a bearing, said bearing configured to receive a PTO shaft, said PTO shaft capable of sliding along an axis of said bearing in relation to an upward and downward movements of said cradle;
- an intermediate sliding member provided on a rear rod of said cradle and extending in a direction parallel to side links of said cradle;
- sliding blocks provided on said PTO frame, said sliding blocks configured to slide along sliding surfaces defined on said side links and said intermediate sliding member of said cradle;
- a PTO coupler coupled at an operative front end of said PTO shaft;
- and
- a PTO locking mechanism for preventing a backward movement of said sliding blocks after said PTO coupler gets engaged with a tool side PTO coupler, wherein said power take-off (PTO) connection mechanism includes a push-pull rod connected between said PTO frame and a fixed position for rod assembly mounting defined on a frame attachment mechanism fastened to said PTO frame of said utility vehicle, said push-pull rod configured to push said PTO frame forward to make it slide along said sliding surfaces when said cradle is lifted up and to apply a pull force on said PTO frame when said cradle is lowered, said power take-off (PTO) connection mechanism further includes a push/pull spring assembly configured to be pivotably coupled with said PTO frame.
