Bought my Fastrack 3 yr's ago. With a Honda 20-52,Love the way it does the job, Started to notice that is was not throwing the grass like it used-to. Checked engine rpm was only turning 3300 rpm, re-clocked to 3500. It now throw's grass about 100"s. Truly unbelievable, It now will cut grass as fast as I can control the tractor. Question: Is 4% over Mfg. recommendation going to over clock the deck or anything else?
