3 Pack of Fisher Barton Marbain Steel (XHT) mower blades for most Stihl 52" mowers, replacing Stihl part number WB03-710-6000-A (BLADE SET, 18 x 2.5 x .25 x 2.5, 1 3.5).  Each blade is 18" long with a 5/8" center hole and a medium lift - notched sail. 

The only difference between this blade and the OEM blade is the thickness.  This blade is .2 inch thick and the OEM blade is .25 but is made from the same hardened steel.

This is an XHT mower blade. That means it is made from Marbain Steel, the best steel a mower blade can made out of. You can expect it to last longer than your OEM blade or other inferior aftermarket blades. These blades are rated the Rockwell "C" hardness level. They wear 33% slower than traditional mower blades and are 40% less likely to bend or break. Perfect for sandy soil conditions, mowing rough terrain, or, best yet, manicuring a beautiful, well-maintained lawn.
