Description
Overview:
The Blade Support M53 25mm is a genuine Husqvarna component for professional walk-behind rotary mowers, including the LB553S and LB553Se. It is a robust metal hub that securely locates and supports the cutting blade, transferring drive from the engine crankshaft while helping maintain balance and smooth operation. Built for regular lawn and grounds maintenance, it is engineered to handle the demands of commercial and residential use. The 25 mm centre bore suits the 25 mm crankshafts used on these models, ensuring an accurate fit and consistent blade retention. Supplied as an original Husqvarna part, MPN 501110701 (OEM 501 11 07 01), it helps restore cutting performance, reduce vibration, and protect the engine by keeping the blade correctly seated and aligned.
