A month and a half ago I ordered a new set of mower blades for my 1650 (48" mmm) at Jacks Small Engines. The guy said at that time he didn't know how much longer they'd still be available. I got that set, wanted to make sure they were the right ones before ordering another set, so I ordered another set of blades. Yesterday they called and told me the blades are no longer available. Anyone know of another source of blades for these old mowers?
