I'm a newbie, getting a B2601. One of the things the neighborhood kids have asked me to do is level the volleyball court. It's about an 18-in drop from one corner to the other. Any suggestions on how to level this? Should I pick the center as a level point and cut the high point and raise the lower point? Yard continues to drop off gradually on the right hand side off this photo. Any attachments you'd recommend for doing this. Thank you.
