Abstract
A two speed power take-off with a reversible adaptor flange and a connected drive shaft for connection to either of two drive flanges rotating at different speeds. The adaptor flange has an inner and outer transition area with a plurality of bolt holes drilled in each area. The axes of the bolt holes in each area are at different angles such that the holes in one transition area match with receiving holes in one drive flange and, when the adaptor flange is reversed, the holes in the other transition area match with the receiving holes in the other drive flange.
