ABSTRACT:
The apparatus and method of this invention pertain to the sharpening of the blades of a reel mower having a framework about the reel. The apparatus comprises a belt having protuberances thereon, an assembly of pulleys and a drive motor for driving the belt and guiding the belt and protuberances to engage with the blades of the reel mower. The method of the invention is to use the apparatus of this invention and place it in a position so that, when the belt is revolved about the pulleys, the protuberances engage the blades of the reel mower thereby causing the reel to rotate in an opposite direction from the belt movement.
