I am thinking about buying a 48" exmark TTHP from a friend and would like to add a velkie to it. Which would be the best velkie for a hydro walkbehind?? Do the proslides work well on St augustine?? Can you make a 180 degree turn while standing on the proslide or do you have to get off it?? I've borrowed a 2 wheel velkie to try out behind a 36" belt scag I have, but haven't had the chance to use it with all the rain. I noticed most of the people who like the proslides are from up north where you stripe lawns, but I'm wondering what it would look like on a 3.5" st augustine yard??
