1. A method of sharpening bedknives adapted to be installed in a reel blade mower by means of a pivot mounted at each end, comprising the steps of:

  • mounting a spaced set of horizontal locator surfaces on a fixed support rail in a bedknife grinder;

    positioning each bedknife to be sharpened against said horizontal locator surfaces, with the bottom of said bedknife against said horizontal locator surfaces;

    energizing an electromagnet associated with each locator surface set to hold the bedknife against the surfaces, and thereafter operating the bedknife grinder by traversing the grinding wheel along the bedknife so as to sharpen the bedknife as it is held in against said locator surfaces.
