Stuck rack is typical for a unit that has set a long time. Old fuel/varnish, a little condensation/moisture and things glue themselves together. Much worse with the later sleeve metering pumps.
I have the workshop manual for the 977H which also has the D333 engine, if you need anything engine related I'll be happy to scan it for you! Glad to hear you got the old girl going!
That is a cable control unit. Used for cable operated blade or cable operated scraper. They are direct coupled to the pto shaft, no means for disconnect. They are not meant to be used as a towing winch and do not have the capacity to do towing winch duty.
Cable operated scraper? WHERE DO I GET ONE OF THOSE LOL!
If it is direct coupled shouldnt you be able to see the drums or breaks turning when the clutch is engaged? or at least thats what I remember of my dads old cable D6. I was very young and my memory could be skewed.
To bad this is not closer or id be on it like a hobo on a hot dog!

I think you need one size bigger anyway. they are around.
there was a Letourneau out in Indiana pretty reasonable... but you need to be sure that the pan you get is sized to fit your tractor too wide and you cant pull it, too narrow and it destroys your tracks.
1st pass is no problem. For the 2nd pass you have created a channel that is the width of the scraper cutting edge. If that channel is only slightly less than the measurement over the outside of the tracks then you'll have the outside edge of the tracks trying to run on top and the inside edge trying to run down in the channel. Not good for the tracks in the long term.
