thanks for the response, I might go demo one this weekend. The steering is controlled by applying brake to one wheel, right?
Not exactly. Mine is a hydro unit that operates the same as a zero-turn riding mower, with infinitely variable forward and reverse on each wheel. Technically it is a zero-turn mower. Mine also has a floating deck for easy height adjustment. A more economical solution would be a belt-drive unit which provides power via belts connected to each wheel via tensioners and a multi-gear transmission. You turn by reducing power to one wheel with the handlebar lever. Reverse is really just a reverse assist. Personally I can't stand belt-drive units having been spoiled with a hydro one. I don't know if they still make units with a direct drivetransmisdions with turning brakes. My uncle had an old Deere set up that way.
