hello all,
  New member here. Been a lurker for a while and have gleaned a lot of useful information. Now I have a problem I could use some help. 1978 Allis,7000. It does not have differential lock, but all of a sudden it acts like it does. Just driving tractor only it steers, but with a round bale on the 3 pt. You can't turn it, not even using the breaks. I suspect something is wrong in the final drive, but what? Thanks for any help

The differential is locked up. There is a dipstick directly behind the cab under the SMV sign. I'm guessing your PTO seals have been leaking oil and that compartment is very low on oil.  Wheels have to come off. Axles get pressed out of their tubes. Brakes/brake housings come off. Lift arm housing comes off next. Then, you are down to the differential with the ring gear. Cab might have to be lifted a little, but not removed.

thanks Dr.,
  Are we talking major damage or parts not sliding as they should? I did pull the dipstick, it was low but 
Still showed oil on the stick. Thanks again, Bob

Until the weather improves, also don' t have heated shop.

More damage?? Maybe and maybe not really. The affected parts are already junk. If you must continue to use it, overfill it 2 or 3 gallons from the top mark on the stick. Maybe even overfill with diesel fuel to act like penetrating oil inside the differential. It will not hurt doing this.
