A bale processor has a horizontal rotor mounted at the center of an upwardly concave bale support. The bale support rocks from side to side across the rotor to bring new parts of the bale against the rotor. The rocking action produces a rolling, sliding or tumbling motion that is suitable for round bales of any size, including old bales that have settled. The apparatus can also handle square bales and loose material.

Why it's free to use
- Filed June 13, 1996 and granted December 26, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 13, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 13, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
