I have a Exmark Metro 36 and I'm only considering a Proslide XT as I like the idea that I can stand on it when needed and simply step off when not. The online video seems impressive. The website says that it is not recommended for any belt drives or hydro units under 48"; however, I see them all the time on Metro's (36 and 48) for sale or displayed in pictures and 36" hydro units. Do they not recommend them for belt drives because they will kill the drive system or because the machine itself does not have enough counterweight? It would be used on flat lawns only and retracted whenever I encounter a hill or am working in tight areas (the reason I only like the Proslide idea). I would think standing on a plate dispersing my weight (200lbs) would not be harder on the machine than a single wheeled unit? But that's why I'm here asking. I did a search and got limited results. 1 guy asked the same for a 36 belt drive JD and was told my 1 member it would be fine with no more wear and tear on the mower then a wheeled unit, then an argument started about the wear plate from people besides the OP. Another thread people recommended a wheeled unit as they did not like the Proslide system in general. I'm not interested in wheeled units as I don't want something I have to take on and off or hang and swing around the mower. If you all don't advise the Proslide XT is usable on the 36 Metro I'll stick to walking.
