Frequently Asked Fit & Bypass Questions

Q: How do I find my deck size and model number?

Check the model/serial tag under the seat or on the frame; the deck size is in the model name or owner's manual.

Q: Is a Kevlar (aramid) belt worth it?

Aramid-cord belts resist stretch and heat far better than plain rubber belts and are the OEM spec for most decks listed here.

Q: Will a different star-pattern blade fit if it's the same length?

No. The center hole must match the spindle exactly or the blade can spin loose — a safety hazard.
