A FEW POINTERS

Choose with your garden in mind.

What matters most

  • Compare the approved part number with the exact mower.
  • Follow the model's replacement and maintenance instructions.

Where the tradeoffs land

  • Blade length alone cannot establish compatibility.
  • Similar blade shapes can have different mounting details.
GOOD QUESTIONS

Before you head outside

Can I choose a blade by deck width?

Start with the mower's approved-parts information. Deck width is only one clue and does not establish the correct blade, mounting, or arrangement.
