What would his machinery line up look like ?
Would he be subjecting the soils to the heavy axle loads of todays Planters, tractors, combines, grain carts and livestock waste spreading devices ?
After seeing his AC no-till planter, got me to thinking since then - His whole machinery line, back then, was light weight - as compared to today  . . . . .
Also, couldn't help notice how deep he was culitvating - so close to the plant (root pruning ?) . .  . . 
Just a few thoughts I had after watching the Vid and this thread on current land condition ~
