This is going to sound so elementary, I'm almost embarrassed. But I have only used belt driven mowers in 8 years of the business, so I have to ask. I just bought a Quick 36. It's hydrostatic. There are no grips to change direction. Do you literally just angle the mower manually to change directions? This is easier than pulling a grip to change the direction? How the hell does that work? I haven't tried it yet because its just to cold. Sorry so basic, but I can't believe that's all there is to it.
