Terrible Bush Hog Performance

Yep, tall grass requires a different mindset than even weeds... I can mow tall weeds and Johnson grass at a pretty quick clip but get in tall fescue or Bermuda and it slows to a crawl... When I say pretty quick I mean I have 12 forward gears and I can mow it at speed 6 at 2500 engine RPM. Fescue and Bermuda require speed 5...
