Abstract
A tractor hitch assembly comprises a drawbar with a hydraulic pump mounted to a pump mount extending below the drawbar and drawbar couplers formed thereon. A trailer tongue coupler is pivotally connected to the drawbar for pivoting about a roll axis and a yaw axis. The tongue of a trailer is removably securable to the trailer tongue coupler in a plurality of selected vertical alignments. The trailer tongue is formed integral with a main beam of the trailer frame extending the length of the trailer.
Claims11
A hitch assembly for connecting a trailer to a tractor, said hitch assembly comprising:
- a drawbar having drawbar couplers mounted on opposite ends thereof, each drawbar coupler adapted for coupling to a tractor coupler assembly connected to the tractor;
- a pump mount connected to said drawbar and extending below said drawbar and said drawbar couplers;
- a hydraulic pump mounted on said pump mount and supported below said drawbar and said drawbar couplers;
- a pivot assembly comprising a roll pivot platform pivotally connected above and to said drawbar between said drawbar couplers;
- said roll pivot platform pivotal about a roll axis aligned with a direction of travel of the tractor to which the hitch assembly is to be connected;
- said pivot assembly further comprising a trailer tongue coupler removably securable to a tongue of a trailer, said trailer tongue coupler pivotally connected to said roll pivot platform and pivotal about a yaw axis extending perpendicular to said roll axis.
A pull-type trailer for a tractor including a pair of lift arms, said trailer comprising:
- a trailer frame including a main beam having a trailer tongue integrally formed therewith, said main beam extending substantially the entire length of said trailer along a longitudinal axis thereof;
- a hitch assembly for connecting the trailer frame to the lift arms on the tractor, said hitch assembly comprising:
- a drawbar having drawbar couplers mounted on opposite ends thereof, each drawbar coupler adapted for coupling one of the pair of lift arms thereto;
- a pump mount connected to said drawbar and extending below said drawbar and said drawbar couplers;
- a hydraulic pump mounted on said pump mount and supported below said drawbar and said drawbar couplers;
- a pivot assembly comprising a roll pivot platform pivotally connected above and to said drawbar between said drawbar couplers;
- said roll pivot platform pivotal about a roll axis aligned with a direction of travel of the tractor to which the hitch assembly is to be connected;
- said pivot assembly further comprising a trailer tongue coupler removably securable to the tongue of the trailer frame, said trailer tongue coupler pivotally connected to said roll pivot platform and pivotal about a yaw axis extending perpendicular to said roll axis;
- wherein said trailer tongue is selectively securable to said trailer tongue coupler in a plurality of vertically spaced alignments.
