## Abstract

A baler is comprised of a plurality of reversibly driven belts or chains supported on a plurality of transverse rollers and defining an expendable bale-forming chamber. A bale discharge gate is provided for opening the chamber and discharging a bale therein onto the ground. The gate includes at least a portion of the belts or chains and a motor for driving the belts or chains in a direction opposite to that used for bale formation and is further operable to bring a portion of the belts or chains into contact with a discharged bale and to displace the bale rearwardly from the baler along the ground.

## Claims

### Claim 1

In a round baler comprising:
a plurality of transverse rollers;
means supported on said rollers and defining a bale forming chamber for forming a bale of generally cylindrical shape; and
a bale discharge gate means for opening said chamber and discharging said bale on the ground; the improvement comprising:
said gate means further comprising bale drive means for contacting a bale discharged on the ground and for displacing said bale along the ground away from said baler.

### Claim 2 (depends on 1)

The baler of claim 1 wherein said bale drive means comprise a span of said chamber defining means.

### Claim 3 (depends on 1)

The baler of claim 1 wherein said chamber defining means is a front set of belts and a rear set of belts carried by said gate means, said bale drive means includes (1) said rear set of belts supported on one of said rollers, (2) a supporting arm mounting said one roller and (3) means for displacing said arm responsive to the opening of said chamber to maintain said rear set of belts in contact with a bale discharged on the ground.

### Claim 4 (depends on 3)

The baler of claim 3 wherein said gate means includes a hydraulic cylinder connected to said arm for displacing said arm and said one roller when said chamber is opened.

### Claim 5 (depends on 1, 3, 4)

The baler of claims 1, 3 or 4 further comprising means for driving said chamber defining means in a first direction such that a span thereof which defines the rear of said chamber is displaced upwardly and wherein said bale drive means includes means for driving said span in a second direction opposite to said first direction when said chamber is opened.

### Claim 6 (depends on 5)

The baler of claim 5 further comprising clutch means are provided for disengaging said means for driving said chamber defining means and wherein said bale drive means includes a hydraulic motor for driving said span in said second direction.
