I just ordered 6 sets of blades for my Hustler from J Thomas. I was wondering if anyone has tried their blades on their mowing equipment and if they are as durable as OEM blades. They are about half the price of dealer supplied OEM blades. I try to support my dealer when ever I can, but a 50% savings on blades can't be ignored. Any comments about quality or durability of J Thomas' blades.
