Chris B, Matt G, Dale M, Jason - You go down to the SANDBOX in the Custom TIN thread and look at the home-made sleeve hitch I made for My 72 MANY years ago (20-25) to pull My Ohio Steel Fabricators plow You'll see I don't have much extending down below the factory rearend of the 72 and even with the 23-8.50 X 12 'Stones I have had bean straw build up under the rearend so bad that I've gotten high centered on the rearend and spun-out at plowdays. Even with My 982 and the 26-12.00X 12 'Stones at the one PD I took it to I really had to watch for fear of getting It high-centered. Just not a whole lot of room under those CC rearends when You drop the right rear tire into the furrow if it's more than 6-7" deep! Your not going to hurt anything under there since it's all heavy cast iron but it IS embarassing! Over at the RPM Forum there's even been a few guys complain about Full Size FARMALLS with Fast-Hitch getting hung up when plowing with tractors like 706/806, and the 56 & 66-series where the Fast-Hitch was still common.
