Creeping forward 4300HST John Deere

[Boondoggle]

I have recently noticed that my John Deere 4300 HST is creeping forward when I am not touching the forward pedal but the engine is at higher RPM. It happens in all 3 gears, low, medium, and high.
I was drilling holes with my 3 point auger attachment and the tractor was pulling away from the hole.
Any suggestions? What do I need to look at?

You should be looking at the centering adjustment for the forward/reverse pedals.
