An axial separator for an agricultural combine. The axial separator comprises two side-by-side axial separator units. Each axial separator unit has a rotor that rotates in and is housed in a casing. The bottom rear of the axial separator is open and forms a discharge area into which straw falls. To more evenly distribute the straw along the width of the combine a wedge shaped deflector is positioned in the last quarter of the discharge area below and between the rotors.

Why it's free to use
- Filed May 7, 1992 and granted November 8, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 7, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 7, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
