Abstract
Abstract A hay baler capable of forming large cylindrical bales of hay utilizing a single continuous belt is disclosed. The baler has forks for picking up loose hay from the ground and transporting the hay to an elevated position to be gravity fed to a baling section. A loop of a single endless belt, or parallel endless belts spaced to perform the same function as a single belt, forms a baling section. The large loop of a single belt rolls the hay into a cylindrical bale. The baler generally propells the belt from a power take off from a tractor or from the wheels of the baler and discharges the bale from the rear of the baler.
