I bought a used 52" Toro Proline Hydro (Only 40 hours) and it looks like it is in showroom condition. Runs great, cuts awesome but I am having an issue with hydros in reverse. It has the T-bar steering system (which I love) and when I pull back on the handle, it creeps VERY SLOWLY in reverse and not equally with both tires. If I am on a hill, forget about reverse altogether. It just ain't happening. I have looked at my owners manual and am thinking that it may have something to do with some sort of adjustment on the by-pass valves on the hydros. Any other ideas would be appreciated. Thanks!
