I recently tried to purchase a second set of Oregon Gator blades for my 44A mower deck. Oregon part number is 90-957. Much to my dismay, I find that these are no longer being produced by Oregon. The set consists of 3 equal length blades, 15.3" length, 2.5" width. I like the cut and lift that these blades provide. Does anyone know of a suitable replacement that's currently available? Does anyone have a good used set that they are willing to sell?
