No. This blade set fits select applications only. Match your original blade number, blade length, center-hole style, deck layout, and mower model before ordering.

Which package quantity should I choose?

For 3-blade decks, select the 3-Pack for one complete blade change or the 6-Pack for two complete blade changes.

What should I check before installing?

Compare blade length, center-hole pattern, lift style, deck layout, and original blade number against your mower or OEM diagram. Stop installation if the blades do not match your original setup.
