I have never actually gone and tested out any hydro w/b's other than Ferris products. I've looked at some in pics and stuff. On some of them I'm trying to figure out how the controls work. I just read a post about a hydro with a forward/reverse lever and some other things that just seem odd to me. The Ferris stuff I have has two levers on each side you control with your thumbs that control the hydro unit. Push forward the wheel turns forward, pull back you go in reverse. Like the levers on a ZTR. It seems like from the pics I've seen a lot of mowers have all these extra levers and stuff. On other hydro W/B do you have to "shift" it into reverse or something? From the pictures it looks like they are just like belt drives as far as how they operate. I should get off my but and test drive some other brands I guess. I just always assumed that the controls were the same if not very similar.
