For the best mowing results, it is important that blades are correctly sharpened and not damaged.
Replace blades that have been bent or cracked when hitting obstacles.
Let the service workshop decide if a blade with large nicks can be repaired/ground or must be replaced. Balance the blades after sharpening. Check the blade mounts.
CAUTION! Blades are sharp. Protect your hands with gloves and/or wind heavy cloth around the blades before handling. The sharpening of blades must be carried out by an authorized service workshop.
