Specs At A Glance

Good To Know

Q: How often should mower blades be replaced? A: Replace them when edges dull, bend, or leave ragged grass tips, often once a season for regular mowing. A sharp set keeps the cut clean and reduces stress on the deck.

Q: Do these blades need balancing before installation? A: Check balance after sharpening or if a blade takes an impact, since unbalanced blades cause vibration. Verify the part number matches your deck before mounting.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
