Abstract
Abstract A hay bale rolling apparatus is adapted to be drawn along a windrow of hay behind a tractor to roll the windrow into a series of separate bales in contact with the ground. A wheeled chassis has parallel side beams with transverse pivot means forward of the wheels. A frame provided with bale forming means has its front end mounted on the pivot means. When a bale reaches a predetermined size, power means located behind the wheels tilts the frame upwardly about the pivot means to raise the rear of the unit and release the bale. The apparatus then returns to normal position to start a new bale.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
192 words
Hay bale rolling apparatus comprising, in combination: a chassis including a pair of parallel side beams provided with supporting wheels which are adapted to span a windrow of hay; a frame between the side beams, said frame defining a baling chamber which is open at the bottom; means in the frame for rolling hay in a windrow into a manageable bale as the apparatus is moved forwardly along the windrow; transverse pivot means at the front of the frame which mounts the frame on the chassis for upward tilting movement about said pivot means; a pair of extensible and retractable units to the rear of the pivot means, said extensible and retractable units being pivotally connected at one end to the chassis and at the other end to the frame, and said units having a retracted running position in which the open bottom Of the frame is near the ground and an extended bale releasing position in which the frame is tilted upwardly about the pivot means; means for actuating said units when a bale reaches a desired size to extend the units; and means for returning the units to running position.
Claim 2
Dependent Claim
192 words
Hay bale rolling apparatus comprising, in combination: a chassis including a pair of parallel side beams provided with supporting wheels which are adapted to span a windrow of hay; a frame between the side beams, said frame defining a baling chamber which is open at the bottom; means in the frame for rolling hay in a windrow into a manageable bale as the apparatus is moved forwardly along the windrow; transverse pivot means at the front of the frame which mounts the frame on the chassis for upward tilting movement about said pivot means; a pair of extensible and retractable units to the rear of the pivot means, said extensible and retractable units being pivotally connected at one end to the chassis and at the other end to the frame, and said units having a retracted running position in which the open bottom Of the frame is near the ground and an extended bale releasing position in which the frame is tilted upwardly about the pivot means; means for actuating said units when a bale reaches a desired size to extend the units; and means for returning the units to running position.
Claim 3
Dependent Claim
30 words
The apparatus of claim 1 in which the side beams converge forwardly of the frame to provide draft means which is adapted to be coupled to a tractor draw bar.
Claim 4
Dependent Claim
22 words
The apparatus of claim 1 in which the wheels are generally midway between the pivot means and the rear of the frame.
Claim 5
Dependent Claim
16 words
The apparatus of claim 3 in which the extensible and retractable units are behind the wheels.
Claim 6
Dependent Claim
19 words
The apparatus of claim 1 in which the extensible and retractable units are near the rear of the apparatus.
Claim 7
Dependent Claim
52 words
The apparatus of claim 1 in which the pair of extensible and retractable units is mounted to the rear of the pivot means, said units having a retracting running position and an extended bale releasing position, and the means for actuating the units extends them when a bale reaches a desired size.
