Ahhh, yes this to set 6 high Tote stacks instead of 12 high hay bales could & would be the trick....A 78" High tilting Flop Bot! The Front Tote Manipulator is 1/2 of the Flop Mechanism also. And the wheels span the platform for the backup & tilt dump of that 6 high tightly packed tote stacks (3 for Auto+Room to spare for a bin too on the Auto Stack), the way it can roll Totes helps w/ those upside down totes too (rotate those only once instead of twice, then slide and lock them together). "The Wall Building Machine." The Drive Team/Human Player only has to Tilt it back up into vertical orientation again and lift it onto the cart to get it back into the "Transport Configuration."
