Fitting & ordering notes
- Check the centre hole first. This blade mounts on a 5-point star spindle — if the hole pattern on your old blade differs, it will not seat.
- Packaging. Ships in MowForge export packaging marked with our code 405380 — the cross-reference numbers above are for ordering convenience only.
- Finish. Cutting edges arrive with a protective paint coating for sea freight and handling; the coating wears off after the first few mows.
- Quality records. Every batch is hardness-sampled into the 45–50 HRC window and dimension-inspected before packing — inspection records ship with the order on request.
- OEM/ODM. Laser marking, private labels and retail or bulk packaging are available on this part.
