  • Patent number: 11926293
    Abstract: A mounting mechanism (100), to enable hitching a tool (101) with the frame of a utility vehicle, comprises front hooks (102), a locking mechanism (104), a lifting cradle assembly (106), and a frame attachment mechanism (108). The front hooks (102) and the locking mechanism is configured to detachably engage the front and the rear portion of the tool (101) respectively. The cradle assembly (106) is configured to be operatively engaged with the front hooks (102) and the locking mechanism (104). The frame attachment mechanism (108) is configured to be pivotally coupled to the lifting cradle assembly (106). The locking mechanism (104) is configured to be operated by lifting the cradle assembly (106) via pivotal motion between the cradle and the frame attachment mechanism (108) under force generated by the vehicle (1000) to hitch and lock the tool (101) with the frame of the vehicle (1000).

  • Publication number: 20230031811
    Abstract: A power take-off PTO connection mechanism (100) for mid mounted tools (101) of a utility vehicle (1000 includes three main assembly members: a frame attachment mechanism (108), a vertical moving frame (or cradle) (106), and a PTO assembly (128). The frame attachment mechanism (108) is fixed to the frame of the vehicle or tractor (1000). The PTO connection mechanism (100) of the present invention helps is easy and quick connection of the PTO shaft to a variety of tools (101) with the tractor. The PTO shaft remains in continuous contact with the tool power input once it is moved in an engaged position.
