We have been using motor oil in our 544k industrial loader's hydraulic system since it was new and it has 10000 hours now. No problems so far.
Older tractors are pretty forgiving generally. Our JD 4620 (old 2wd 135HP tractor) lacked all the emissions and nannies of modern tractors so, I doubt lightweight motor oil would have damaged the hydraulic system, transmission, or rear end. Either of the two hydraulic oils at the ABC Autoparts would be a safe bet as well.
With my Massey or Kubota, I'd be looking at thousands in repair costs if I used either of those oils.
Comparing an 'antique' tractor and a modern one is a bit like comparing a horse and buggy to a modern pickup.
