Description
Overview:
This blade boss is a metal mounting hub that secures the cutting blade to the mower crankshaft and keeps it correctly centred for safe, consistent cutting. It is designed for Mountfield walk‐behind lawnmowers and matches OEM reference 122465607/4. Built from robust cast metal for long service life, it transmits drive from the engine to the blade while maintaining alignment and reducing the risk of slippage when the blade bolt is correctly tightened. A mounting diameter of 22.2 mm (approximately 0.87 in, 7/8 in) suits a wide range of Mountfield machines. Ideal as a direct replacement during servicing or after impact damage, it restores stable blade seating and reliable mowing performance on popular models such as the SP42 and SP46.
