I live in Florida and I mow St. Augustine and Bahia grass. I am having problems with clumping, even if I go a a snails pace. Is there anything I can do with my deck to fix that problem or maybe the spacers. My blade spacers have one on top and two just above the blade. The rest of the machine is set up from my dealer the same way since last September. Oh yeah and it is a 52inch super surfer with the 23 hp Kawi engine.
