Someone post a pic of the pedal, I want to see if it's changed any from the older models. I think mine needs adj too. The reverse hasn't bothered me too bad, but it doesn't come to a quick stop when I release the fwd pedal, if I want a quick stop I have to touch the rev or jump on the brakes.
I drove a CC zero turn tractor that I helped pick out for someone else. MAN...those things are sweet, turn on a dime and give you change back. Too bad it's not as durable for GT uses. Anyhow, it would about give you whiplash when you released the pedal. Mine doesn't really creep, just slows gradually.
