Abstract
Abstract A multiple implement to tractor hitch assembly. A horizontally disposed elongated first beam is horizontally curved and connected intermediate its ends by a tongue with a tractor drawbar for horizontal pivoting movement of the first beam about the vertical axis of its tongue connection for positioning implements when connected with respective parallel end portions of the beam in a tandem or laterally spaced soil working position by a power cylinder extending between the first beam and the tongue. A second substantially identical beam is hingedly connected in tandem by one of its ends to the trailing end of the first beam for vertical pivoting movement of the beams about the horizontal hinge connection. An agricultural implement is connected with the beams at their hinged connection and with the respective other end of the respective beam.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
224 words
An implement pulling hitch assembly, comprising: beam means including first and second rigid unitary elongated horizontally curved beams each having its respective end portions facing the same direction in spaced-apart relation, said second beam being hingedly connected by one of its end portions with one end portion of the first said beam for vertical pivoting movement of both beams with respect to each other about a horizontal axis; coupling means at the hinged juncture of said beams and on the respective other end portion of said beams for connecting agricultural implements thereto; tongue means including an elongated tongue adapted to be pivotally connected at one end portion with a tractor hitch and hingedly connected at its other end portion with one end portion of said beam means for horizontal pivoting movement with respect to each other about a vertical axis; a plurality of ground engaging caster wheel means mounted on and horizontally supporting said beam means above the surface of the earth; and, power means including a single pressure operated cylinder extending between and connecting the tongue with said one end portion of said first beam for horizontally pivoting said beam means about the vertical axis and moving said beam end portions from a laterally directed implement tandem travel position to a rearwardly directed implement laterally offset forward to rearward staggered soil planting position.
Claim 2
Dependent Claim
224 words
An implement pulling hitch assembly, comprising: beam means including first and second rigid unitary elongated horizontally curved beams each having its respective end portions facing the same direction in spaced-apart relation, said second beam being hingedly connected by one of its end portions with one end portion of the first said beam for vertical pivoting movement of both beams with respect to each other about a horizontal axis; coupling means at the hinged juncture of said beams and on the respective other end portion of said beams for connecting agricultural implements thereto; tongue means including an elongated tongue adapted to be pivotally connected at one end portion with a tractor hitch and hingedly connected at its other end portion with one end portion of said beam means for horizontal pivoting movement with respect to each other about a vertical axis; a plurality of ground engaging caster wheel means mounted on and horizontally supporting said beam means above the surface of the earth; and, power means including a single pressure operated cylinder extending between and connecting the tongue with said one end portion of said first beam for horizontally pivoting said beam means about the vertical axis and moving said beam end portions from a laterally directed implement tandem travel position to a rearwardly directed implement laterally offset forward to rearward staggered soil planting position.
Claim 3
Dependent Claim
56 words
The hitch assembly according to claim 1 and further including: implement stabilizing means including pivotally interconnected links extending between and pivotally connected with said second beam and an agricultural implement connected therewith; and, other power cylinder means mounted on said second beam and operatively connected with said stabilizing means for extending and retracting the stabilizing links.
