My Ariens GT18 does not keep a constant speed, even on flat ground.


Following the service manual procedure, I have tried to adjust the linkages, but must admit it is a confusing procedure.


I have changed the hydro oil and OEM filter.


No improvement--ground speed still varies a lot. Any idea where to look or what might be wrong?

Welcome to GTtalk!
It sounds like possibly worn linkage to me. On my Gravely 18H which is the same thing as the GT18, the rod connecting the control arm on the hydro was worn out. I replaced that and was much better. It was that bad that I could barely find neutral any more.
