Abstract
A winch assembly for use with a tractor having a power take off (“PTO”) includes a winch framework releasably coupled to a rear portion of the tractor. The winch framework does not inhibit connection of an implement to a three point or drawbar hitch of the tractor. A winch having a cable reel is mounted in the winch framework and coupled to the PTO such that the cable-reel may unwind or retract a cable upon PTO operation. The winch framework may be released from the rear portion of the tractor and coupled to a storage frame mounted elsewhere on the tractor when the winch is not in use. While the winch may be connected to the PTO and used without uncoupling an implement from the tractor, the winch must be removed in order to actively couple the implement to the PTO.
Claims18
A winch assembly for use with a farm type tractor having a power take off (“PTO”) and an implement linkage, said implement linkage being mounted to a rear portion of said tractor and capable of releasable connection to an implement, said winch assembly comprising:
- a winch framework releasably attached to said rear portion of said tractor and positioned so as not to obstruct a connection of said implement linkage to said implement;
- a cable-reel rotatably mounted to said winch framework and having means for releasably coupling said cable-reel to said PTO for rotatably driving said cable-reel so as to selectively unwind a cable therefrom and retract said cable thereabout, said cable having fastening means at a free end thereof for attaching said free end to objects;
- wherein said framework includes:
- a winch frame having a pair of rear support members and a pair of front support members with a plurality of struts extending between respective rear and front support members, said winch frame having a plurality of bosses fixedly attached to and spaced apart along said rear support members;
- and
- a mounting frame having a pair of spaced apart side frame bars with upper and lower frame bars connecting said pair of side frame bars, said upper frame bar being releasably coupled to said rear portion of said tractor, said mounting frame having a plurality of couplings fixedly attached to said side frame bars for releasably receiving and retaining respective bosses therein.
A winch assembly for use with a farm type tractor having a power take off (“PTO”) and a three point hitch, said three point hitch being releasably mounted to a plurality of hitch brackets fixedly attached to a rear portion of said tractor, said three point hitch being capable of releasable attachment to an implement, said winch assembly comprising:
- a winch framework releasably attached to said plurality of hitch brackets on said tractor and positioned between said plurality of hitch brackets so as not to obstruct a connection of said three point hitch to said implement;
- a cable-reel rotatably mounted to said winch framework and releasably coupled to said PTO with a gear linkage for rotatably driving said cable-reel so as to selectively unwind a cable therefrom and retract said cable thereabout, said cable having fastening means at a free end thereof for attaching said free end to objects;
- wherein said framework includes:
- a winch frame having a pair of rear support members and a pair of front support members with a plurality of struts extending between respective rear and front support members, said winch frame having a plurality of bosses fixedly attached to said rear support members;
- and
- a mounting frame having a pair of spaced apart side frame bars with upper and lower frame bars connecting said pair of side frame bars, said upper frame bars being releasably coupled to an upper hitch bracket of said plurality of hitch brackets and said pair of side frame bars being releasably coupled to corresponding side hitch brackets of said plurality of hitch brackets, said mounting frame having a plurality of couplings fixedly attached to said side frame bars for receiving and releasably retaining respective bosses.
A winch assembly for use with a farm type tractor having a power take off (“PTO”) and a three point hitch, said three point hitch being releasably mounted to an upper hitch bracket and a pair of laterally spaced apart side hitch brackets that are fixedly attached to a rear portion of said tractor, said three point hitch being capable of releasable attachment to an implement, said winch assembly comprising:
- a winch frame having a pair of rear support members and a pair of front support members with a plurality of struts extending between respective rear and front support members, said winch frame having a plurality of bosses fixedly attached to said rear support members;
- a mounting frame having a pair of spaced apart side frame bars with upper and lower frame bars connecting said pair of side frame bars, said upper frame bars being releasably coupled to said upper hitch bracket and said pair of side frame bars being releasably coupled to corresponding side hitch brackets, said mounting frame having a plurality of couplings fixedly attached to said side frame bars for receiving and releasably retaining respective bosses, said winch and mounting frameworks being configured so as not to obstruct a connection between said three point hitch and said implement;
- and
- a cable-reel rotatably mounted to said winch frame and releasably coupled to said PTO with a gear linkage for rotatably driving said cable-reel so as to selectively unwind a cable therefrom and retract said cable thereabout, said cable having fastening means at a free end thereof for attaching said free end to objects.
