Takes less power, fuel. Cuts great in most grass conditions. Quieter, Safer. However since it has rained now and grass returned to lush spring conditions it leaves a strip behind right front wheel area that is not cut at all. Appears to be from more grass than can be handled in this area, thus reducing blade vacuum. Saw somewhere about double blade on Fastrak. Would this work on my RD?? Should have stuck w/ XR7 deck. Could it be retrofitted to my frame?
