Husqvarna Automower Cutting Disc Kit with Screws | 240mm Cutting Width | 598814401
Genuine Husqvarna replacement cutting disc kit for selected Automower robotic lawn mowers. Includes the cutting disc and three screws.
Designed to securely hold the mower’s three pivoting cutting blades, helping maintain smooth, balanced operation and consistent cutting performance.
Ideal for replacing damaged or worn cutting discs, especially where blade screws have snapped, seized or damaged the mounting threads.
Common Reasons for Replacement
-
Broken blade screws: Screws can snap during blade replacement, leaving part of the screw lodged inside the cutting disc.
-
Stripped or damaged threads: Overtightening, corrosion or repeated blade changes can damage the threaded blade mounting points.
-
Damaged threaded inserts: Worn, loose or broken mounting inserts can prevent blades from being secured correctly.
-
Cracked or bent cutting disc: Impacts with rocks, roots or other hard objects can damage the disc.
-
Excessive vibration or rattling: A damaged or unbalanced cutting disc may cause abnormal vibration or operating noise.
-
General wear: Extended operation and repeated impacts can deteriorate the disc over time.
Replacing a damaged cutting disc helps maintain secure blade attachment, reliable operation and consistent cutting performance.
