CK25 hst creeps

I've had my 2004 CK 25 for a couple of months. When I take my foot off the pedal the tractor often keeps creeping forward. It's very slow, but moving. This week it has started doing the same when backing up. Usually a tap on the other end of the pedal stops it.



Any idea how to fix this?



Thanks,

Jason
