Dan, Does your ground allow you to just disc or do you have to break the soil first? I started out plowing and discing and have since tried to rototill as much as possible. Yes it's slow, but at least in my experiences at my place one pass with the tiller is still faster than the multiple passes I need to get the same results with a plow (1 pass) , disc (at least 2 passes) and drag (another pass).
Glad you like your new toy!
