Tools:
Socket set
Parts Used:

1 Disconnect deck belt and supporting arms.
2 Slide deck from under mower taking care not to damage blade engagement cable.
3 Turn deck upside down exposing blades
4 Remove one blade using impact wrench and holding blade with hand protectd by work glove. (If impact wrench wrench is not available, block blade firmly with solid wood between blade and deck. Turn bolt with box end of wrench. Use of product like WD40 may be required if nut/bolt is rusty.)
5 Identification on blade should indicate top (towards deck) or grass side. One can also copy other blade. Rotate new place into position ensuring star pattern hole in blade seats firmly in identical pattern on pulley.
6 Holding blade firmly in place replace nut/bolt and hand tighten ensuring star pattern remains seated.
7 Blocking blade with solid wood to prevent rotation, firmly tighten nut/bolt.
8 Repeat process for 2nd blade.
9 Reinstall deck.

After a few dozen yards of mowing it is good to shut off mower and check that the blades have not become loose.

Hope this helps
