Offset baler with steerable control

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.

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.

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.

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;
• and forming means for the hay into a cylindrical bale;
• and means for steering said baler transversely relative to said tractor during bale formation thereby controlling the feed of hay along the transverse extent of said zone to form bales of uniform diameter.

In a baler adapted for towing by a tractor, the combination comprising:

• a pickup for picking up hay from a windrow;
• structure defining a bale forming zone for receiving hay from the pickup;
• means for forming the hay into a cylindrical bale;
• and means for towing said baler in an oscillating path encompassing the windrow during bale formation while maintaining the tractor in offset parallel relation to the windrow.

A method of forming cylindrical hay bales of uniform diameter with a tractor drawn baler having a pickup and a bale forming zone which may be of greater width than a windrow of hay to be picked up and baled, comprising the steps of:

• driving the tractor alongside and generally parallel to the windrow;
• towing the baler laterally offset from the tractor and over the windrow;
• picking up the hay from the windrow and feeding the hay into the zone;
• and steering the baler relative to the tractor in a weaving or generally sinuous path across the windrow so that the hay is fed into the zone along its length to form a bale of uniform diameter.
