If you have a XR-7 deck and are unhappy with the Quality Of Cut from the factory Fusion blades or other blades such as the eXmark Lazer notched foil high lifts, I have a solution. I've been mowing with these for a week now in varying conditions. I wanted (and still do) to try a set of VX4 Fusion blades (3" SuperZ type) that are .250" thick. Dealer didn't have these in stock. But he did have these in this picture. They are a .203" thick, 3" wide, 20.5" long SUPER high lift notched foil blade. They create a TON of lift and suction. They throw out clippings further than I've ever seen this deck do so. The QOC is improved tremendously, and grass is vacuumed and cut, not just limpwristed and cut like the OEM's. Deck stays cleaner as well. Here is a picture comparing them to what I ran the past few years (eXmark notched foil high lift fusions) Here is bottom view with number. EXCEL 793935 And lastly a view of the super high lift.
