If you have an angle grinder with a metal abrasive disc on hand, this is a speedier method of sharpening ride on lawn mower blades. Once again, ensure that the angle of the existing edge is followed. Stroke the blade with clean, uniform strokes from the inner to the outer edge.

When using an angle grinder, make quick passes over the mower bar blade and take care that the angle grinder does not get too hot. Friction is generated when the blade is ground, which creates heat.

Eventually, this may result in expensive damage.
