Dad drove this home nearly 100 miles, so she seems sound. comes with duals not pictured. gave under 3 grand for it.
the 7080 was a factory hot-rod. 181 hp on the PTO from a 426 cubic inch I6 built in house. model 670HI. 20 spd semi-manual 10 gears you have to stop for, and a 2spd powershift called the Power Director.
the 670T was in the 7045 (135 PTO HP) , no bypass oil filter, no coolant filter (it was optional though) just turboed and that was it.
the 670I was in the 7060 (161 PTO HP), bypass oil filter, coolant filter, turboed and intercooled. (Allis Chalmers had their name in raised letters on the intercooler, pretty cool IMO)
the 670HI was in the 7080 (181 PTO HP, I beleive 220 at the crank) bypass oil filter, coolant filter, turboed, intercooled, counterbalanced crankshaft, factory fluid type damper., rated RPM 250 RPM higher than others, 2550 Rated RPM.
all had big inboard planetaries, allis finally got their act together on rear ends, to such a degree many models didnt have a maximum working weight limit (weigh it down and pull the shit out of it).
This 7080 has the big cast centers, the 7060's wieghs only a few hundred lbs for the pair, supposedly these weight a few thousand. plus, there is an additional 1K lbs or better added on in extra wheel weight. rims are 18x38, so need to have 20.8R38s, but the PO stuck 18.4x38s on them, way too little rubber on the ground for the power. we will ditch the ugly aftermarket front end weights for some factory ones we have around. we had a factory extra heavy top link kicking around, and so we stuck it on, due to it coming without one.
notice allis was the first to feature many modern features on their tractors. belly fuel tanks that were ground fill, air cleaner ahead of radiator, PFC hydraulics (I beleive first to market) quietest cab in the industry (there is a reason it looked so goofy) inboard planetaries (was mid pack to market with these) etc.
allis was also good about keeping air cold and flowing right. mandrel bent intake tubes, intake on opposite side of exhaust with alternating valves, etc.
anyhow, thats enough drooling for me.

IMo thes ol girls are better than anything deere had to offer, but many will disagree.

at the very least, these deserve more credit than they are given, pretty good ol tractors!
