Cutting Blades

To attain the best mowing effect, it is important that the blades are well sharpened and not damaged.

Bent or cracked blades or blades with large nicks should be replaced.

Blades damaged from hitting obstacles that result in a breakdown should be replaced. The service workshop should decide whether the blade can be repaired/ground or must be replaced. Balance the blades after sharpening.

Check the blade mounts.
