I am a little confused here. Is this happening on a slope or in a spot that you can't ease into the forward motion? Engaging the hydro even on wet grass at high RPM still still be controllable if your not fighting a hill or something. Or is there something out of adjustment possibly on your tractor? I once owned a Kubota sub compact with at least as much power if not more and was easily able to control wheel slip on damp grass.

I could see while turning if you were mowing at a good pace and not pulling back on the hydro in a turn how this could happen... But that would be operator error IMO
