Fig 25 Ensilagecutter Blade

Since the grinder is of small diameter, a hollow-ground surface, as shown at A, Figure 25, would result if the blade were kept in the same place. The thin cutting edge would not stand the wear as well as would a straight bevel as at B. One way to prevent the hollow-ground condition and make a straight bevel is to move the blade forward and backward slightly as it is moved right and left.

Examples of wrong grinding also are shown in Figure 25. The bevels in D, E, and F are rounded and too short, and the blade, even though ground to an edge, would not cut well. The cutting edge is ground back straight, as at G, and then a straight bevel is ground, as at B, which has the same length as the bevel of a new blade, C.
