Abstract
Abstract During a single pass, cut hay or grain in a twenty foot wide swath is cleared by the action of a pair of multiwheel divergent rakes coupled to the front end of a wide wheel farm tractor. The two rakes produce a single five foot wide windrow of hay or grain over which the tractor can pass, and a conventional round baler towed by the tractor produces round bales which are deposited in the field behind the machine. The necessity for separate raking and baling passes utilizing separate tractors is eliminated. The front-mounted rakes can be hoisted and folded to facilitate roadway transport.

Claim 2
Dependent Claim
279 words
A raking and baling apparatus comprising a tractor, a baler coupled with the rear of the tractor and moving therewith, a power lift means on the front of the tractor including an implement support, a pair of multi-wheel fingerwheel rake assemblies connected with and carried by said implement support with the fingerwheels of each rake assembly disposed generally in a plane which is at an acute angle to the path of movement of the apparatus and with the two planes of the fingerwheels of the two rake assemblies diverging forwardly for the purpose of clearing a wide swath extending on opposite sides of the apparatus and producing a single windrow of material cleared from said swath having a width sufficiently narrow to pass between the wheels of the tractor and be acted on rearwardly of the tractor by said baler during a single pass of the apparatus over a field, and said power lift means on the front of the tractor comprising a front end loader attachment including articulated lift arms, cylinder means to raise and lower the articulated lift arms, and additional cylinder means connected to and moving with said arms, a normally level frame coupled with one pair of said arms near the rear of said frame and coupled with said additional cylinder means near the front of said frame, said implement support comprising an additional frame coupled with the last-named frame and extending forwardly thereof, and said rake assemblies each having a primary support arm pivoted to one side of said additional frame near the front thereof and at an acute angle thereto, the primary support arms diverging rearwardly and being substantially normal to said planes.
Claim 3
Dependent Claim
45 words
A raking and baling apparatus as defined in claim 1, and a pair of spaced parallel sleeves fixed on said normally level frame and extending longitudinally of the apparatus, said additional frame having a pair of side longitudinal members which are socketed within said sleeves.
Claim 4
Dependent Claim
46 words
A raking and baling apparatus as defined in claim 1, and means on said additional frame and carrying said primary support arms so that the pivot axes of the primary support arms may have their angular relationships to the longitudinal sides of said additional frame adjusted.
Claim 5
Dependent Claim
64 words
A raking and baling apparatus as defined in claim 3, and flexible substantially non-stretchable restraining means coupled between said additional frame and said rake assemblies to limit rotation of the assemblies in one direction about the axes of the longitudinal side members of the additional frame, each rake assembly including a member having a swiveled connection with one side member of the additional frame.
Claim 6
Dependent Claim
47 words
A raking and baling apparatus as defined in claim 4, and additional means interconnecting the primary support arms and the side longitudinal members of said additional frame to limit rotation of the primary support arms in the direction opposite to that limited by said non-stretchable restraining means.
Claim 7
Dependent Claim
211 words
A raking and baling apparatus comprising a tractor, a baler coupled with the rear of the tractor and moving therewith, a power lift means on the front of the tractor including an implement support, a pair of multi-wheel fingerwheel rake assemblies connected with and carried by said implement support with the fingerwheels of each rake assembly disposed generally in a plane which is at an acute angle to the path of movement of the apparatus and with the two planes of the fingerwheels of the two rake assemblies diverging forwardly for the purpose of clearing a wide swath extending on opposite sides of the apparatus and producing a single windrow of material cleared from said swath having a width sufficiently narrow to pass between the wheels of the tractor and be acted on rearwardly of the tractor by said baler during a single pass of the apparatus over a field, and said rake assemblies being pivotally supported by said implement support on compound axis pivots with a first pivot axis of each rake assembly extending longitudinally of the apparatus and a second pivot axis of each rake assembly extending at an acute angle to the path of movement of the apparatus, the second pivot axes of the rake assemblies diverging forwardly.
