Abstract
A rotary baler for forming large cylindrical bales of cut crop material such as hay and which uses a conveyor belt and an oppositely moving compacting belt arrangement to rotate the hay and form the bale in a baling compartment. Adjustable hydraulic control means are provided for controlling the tension in the compacting belt to thereby control the density of the bale being formed. The hydraulic control means is such that a lower tension force is maintained in the compacting belts during the critical initial start-up phase, and a higher belt tension is provided during the early bale forming stage, resulting in a finished bale of high density.
