Hi I bought a used 36" belt drive gravely last fall and I have been quite happy with the cut. I also bought a pro-slide a month ago but the gravely belts are slipping constantly when I turn or try to go on a slight slope. I am considering buying either the new 32" Exmark hydro or a 36" Ferris hydro. I havn't checked the price on the Exmark yet but the Ferrris is $5200 Canadian. I wonder if I will regret buying the Exmark because of losing the 4 inches of cut? I will buy new belts for the Gravely and see if that helps but if any of you have advise on what machine is better for me I would appreciate it. I do 20 quarter acre lots around 30 regular sized residentials that I can get my 36" into most of them and 3 commercial that are around 8 acres in total. Thanks Marty I will miss the advise of Eric Elm.
