Specs At A Glance

Good To Know

Q: How often should mower blades be replaced? A: Blades typically need sharpening or replacement each mowing season, or sooner if they hit rocks and bend. A dull or unbalanced blade tears grass instead of cutting it cleanly.

Q: Are these blades balanced before shipping? A: Replacement blades are manufactured to a balanced spec, but checking balance before installation is good practice. That helps reduce vibration and keeps the deck cutting evenly.

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