Grinder, for sharpening rotary lawnmower blades, clamps the blade in the same orientation as in the mower with a magnetic blade support to prevent oscillation and a setting mechanism without free play

摘要

The grinder, to sharpen the blades of rotary lawnmowers, has a clamp (1,2,4) to hold the blade in the same orientation as in the lawnmower. A magnetic support (5,6) stabilizes the clamped blade against oscillation during working by the grinding disk (9). The rotary axis is set without play in the two bearing pedestals. Replacement parts give the grinder a cutting action.
