The 786 we had had 38 inch rubber set wide, and the 2+2 had duals, and they were never a problem getting in and out.
A neighbor borrowed our (200+ HP) 1066 to pull a manure tank one time, no matter how many times we told him, he'd pull the TA way too early, and it would slow him down. He normally used something like a 2950, not much on the bottom end. With an IHC you pull it down about 1400-1450 before you pull that lever.
756 took one TA in it's lifetime, my uncle used it for pulling wagons and the planter, plowed with it too. We put two in that 1066 in the 15 or so years we had it, but the second one went in after dad slid down an icy hill with the wheels spinning forward. Tore the hub out of the clutch disk, too.
That 756 is the reason we ran red tractors, grandpa had a 4020 on order at one dealer, went to another that carried a short line for some parts, and they were backing the 756 out of the shop taking it in on trade. He took it for a spin and took it home with him.
