That's cool!!! I wish I was that far along!!! I don't know much about the hydraulics, are you using two valves for the blade tilt? And how is your mix if u are? And I'm getting ready to put some wood floors in my house, I bet the wife would love for me to have a pile of fresh dry dirt in the living room!!! That would be my ultimate playpen!! (Uh and maybe the cats too,, would need excavator to deal with them!!).
