Howdy.
Post away. lots of old ford owners here.
Naa is a transition tractor from ford as they moved away from the n design and before they got to the hundred series.
has a reliable red tiger 134ci OHV engine. fairly bulletproof 4spd crashbox, and an orphaned hydraulic system with top cover and valveing that no other model uses. originally had a square vane pump, those usually get repalced with piston pumps with a little finagling at the plumbing.
post any questions you have.. these are pretty simple machines.

All 4 cyl models can use AL-437 or champion H12 spark plugs instead of OEM Champion H10 or AL 216 plugs.
On the oil filter, it will use a cartridge element napa 1004, fram ch6pl or any that cross.
if it has a spin on conversion, those kits usually take a motorcraft FL1A or any cross ( supertech st8a, fram ph8a, napa 1452, 1515 etc... )
I like 15w40 C/S rated oil in non arctic weather for the engine.
rear end, hyds and diffy are all seperate sumps, and can use a UTF fluid meeting M2C134 specs, or just use that in the hyds and then use 80w90 gl4+ oil in the trans and rear. usually just as easy to use UTF in all rear sumps.
plain green coolant fine. if it has power steering added on, use utf. vs hyd oil IMHO.
#2 grease fine for all the grease points
lube the steering box with 00 grease preferable.. though if the sectors don't leak, you could stick in 85-140 gear oil.
I&T fo-19 is a basic service manual for her.
