I did a search for aftermarket blades and there have been alot of discussion already about blades. However, No one has said where they get their OEM or aftermarket blades. I have MOWMORE & Greenline catalogs. Will the blades they sell work on my Walkers. I have a 1996 Walker T w/48" GHS deck, a 1994 Walker C w/42" GHS deck, and a 2000 48" Side discharge deck. I need extra blades for all of them. I have checked my blade lengths, hole size, and other specs. Some match the Greenline and Mowmore blades. Some don't.
