The drive out is getting a bit long Brian as the roadway is getting narrower all the time with bigger equipment, kinda makes for slow uneasy navigating not to rub the wall or fall off the edge... I'll get what loose dirt there is out of the way, then tear everything out & rebuild it with 1/2" sheet @ 24 inches wide... most of the roadway currently is only 16 inches with most of it 3/8 sheet & some is 1/4, which was fine for the Tamiya trks.
I wish I had this JD850 when I started Mario, I would have done zero hand digging!

Yes, thank goodness for the tunnel project or I'd be just about left with nothing to do... I'll be a few yrs at that before wondering what to do next for a dirtwork project.
Thanx Jason, it's a mighty hauler alright. I knew the clearance was gonna be close, fortunately I didn't have to take a grinder to the B50 to make it fit.
