love mine and havent had a bit of problems. the 50 hour is pricey though the dealer but I was told it might afect my warrantee if I did it myself and something happened to my girl 2300. I did read of a couple of guys having hydrostatic filters broken off on the 2310 one is in this forums and the other on another massey sight I forgot to log. have you heard of such a thing ????
My GC2300 had the same creeping problem. There is an adjustment below the hydro pedal (under the floor board) that increases the spring tension on the pedal. The increased spring tension brings the pedal back to neutral. I adjusted mine and the pedal works fine now. This makes the pedal a little harder to push, but it isn't bad.
