Abstract
Abstract A baler adapted for towing by a tractor to pick up a windrow of hay and roll the hay into a cylindrical bale of substantial size and weight. The baler includes a front mounted pickup and a bale forming structure directly behind the pickup. The bale forming structure is of the type including an endless lower belt and a plurality of upper belts defining an expansible bale forming zone in conjunction with the lower belt. Suitable bale-density and bale-discharge structures are included. The baler includes a wheeled frame which provides a pivot connection for a draft tongue laterally offset from the baler centerline. The draft tongue extends forwardly for hitching to a tractor which can be disposed in towing relation alongside the windrow. A hydraulic cylinder is mounted between the baler frame and the draft tongue for powered steering of the baler relative to the windrow. This enables the operator to feed the hay into the bale forming structure in a systematic flow to build bales of uniform diameter and density end-to-end.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
78 words
In a baler adapted for towing by a tractor, the combination comprising: a pickup for picking up hay from a windrow; means defining a transversely extending bale forming zone for receiving hay from the pickup; means for forming the hay into a cylindrical bale; and means for selectively steering said baler transversely relative to said tractor during bale formation to control the feed of hay along the transverse extent of said zone to form bales of uniform diameter.
Claim 2
Dependent Claim
78 words
In a baler adapted for towing by a tractor, the combination comprising: a pickup for picking up hay from a windrow; means defining a transversely extending bale forming zone for receiving hay from the pickup; means for forming the hay into a cylindrical bale; and means for selectively steering said baler transversely relative to said tractor during bale formation to control the feed of hay along the transverse extent of said zone to form bales of uniform diameter.
Claim 3
Dependent Claim
105 words
In a baler adapted for towing by a tractor, the combination comprising: a pickup for picking up hay from a windrow; means defining a transversely extending bale forming zone for receiving hay from the pickup; means for forming the hay into a cylindrical bale; a draft structure having a pivot connection to said baler and adapted for coupling to the tractor; and power means for oscillating said baler horizontally about said pivot connection during bale formation to shift the pickup transversely back and forth relatively to said windrow so that hay is fed into said zone along its length to form bales of uniform diameter.
Claim 4
Dependent Claim
105 words
In a baler adapted for towing by a tractor, the combination comprising: a pickup for picking up hay from a windrow; means defining a transversely extending bale forming zone for receiving hay from the pickup; means for forming the hay into a cylindrical bale; a draft structure having a pivot connection to said baler and adapted for coupling to the tractor; and power means for oscillating said baler horizontally about said pivot connection during bale formation to shift the pickup transversely back and forth relatively to said windrow so that hay is fed into said zone along its length to form bales of uniform diameter.
Claim 5
Dependent Claim
154 words
An improved baler for lifting hay from a windrow and forming the hay into cylindrical bales, comprising: a mobile frame adapted to be towed by a tractor; a transversely elongated pickup on the frame for picking up the windrowed hay; means defining a transversely extending bale forming zone on said frame for receiving hay from said pickup; means for forming the hay into a cylindrical bale; an elongated draft tongue adapted to be coupled to the tractor and having a pivot connection to said frame proximate to one side thereof whereby the tractor may be disposed transversely offset from the baler and alongside the windrow during baling; and power means operative between said frame and said tongue for oscillating said frame about said pivot connection during bale formation to shift the pickup transversely back and forth across the windrow to feed hay into the zone along its length to form bales of uniform diameter.
Claim 6
Dependent Claim
154 words
An improved baler for lifting hay from a windrow and forming the hay into cylindrical bales, comprising: a mobile frame adapted to be towed by a tractor; a transversely elongated pickup on the frame for picking up the windrowed hay; means defining a transversely extending bale forming zone on said frame for receiving hay from said pickup; means for forming the hay into a cylindrical bale; an elongated draft tongue adapted to be coupled to the tractor and having a pivot connection to said frame proximate to one side thereof whereby the tractor may be disposed transversely offset from the baler and alongside the windrow during baling; and power means operative between said frame and said tongue for oscillating said frame about said pivot connection during bale formation to shift the pickup transversely back and forth across the windrow to feed hay into the zone along its length to form bales of uniform diameter.
Claim 7
Dependent Claim
156 words
An improved baler for lifting hay from a windrow and forming the hay into a cylindrical bale, comprising: means defining a bale forming structure of a given transverse extent adapted to receive hay; means for rolling the same into a cylindrical bale; a pickup disposed forwardly of said structure for lifting hay from the windrow and feeding the same rearwardly into said structure; a wheeled frame supporting said pickup and said bale forming structure for towing by a tractor, said frame including a portion projecting transversely beyond a side of the bale forming structure; a draft structure pivotally connected to said frame portion adapted for coupling to the tractor while disposed alongside the windrow; and power means operative between said frame and said draft structure for steering the baler relative to the tractor during bale formation so that hay may be fed uniformly into the bale forming structure while the tractor is driven alongside the windrow.
Claim 8
Dependent Claim
156 words
An improved baler for lifting hay from a windrow and forming the hay into a cylindrical bale, comprising: means defining a bale forming structure of a given transverse extent adapted to receive hay; means for rolling the same into a cylindrical bale; a pickup disposed forwardly of said structure for lifting hay from the windrow and feeding the same rearwardly into said structure; a wheeled frame supporting said pickup and said bale forming structure for towing by a tractor, said frame including a portion projecting transversely beyond a side of the bale forming structure; a draft structure pivotally connected to said frame portion adapted for coupling to the tractor while disposed alongside the windrow; and power means operative between said frame and said draft structure for steering the baler relative to the tractor during bale formation so that hay may be fed uniformly into the bale forming structure while the tractor is driven alongside the windrow.
Claim 9
Dependent Claim
63 words
The subject matter of claim 4, wherein said frame portion includes transversely spaced stop structures effective to limit the range of steering movement of the baler relative to the draft structure, one of said stop structures being mounted for selective swinging movement away from the other thereby providing an additional range of movement of the baler to a transport position behind the tractor.
