I’ll have to go out and check, but..
I’m guessin that the grease fitting in the steering box is a threaded, 1/8 NPT. So,..
2, 5 packs of
Miniature Brass Barbed Tube Fittings (McMaster-Carr part # 5454K65) should be enough to do the 4 tractors that I have;

I would need 2 of the two packs of the
Through-Wall Couplings (McMaster-Carr part # 5454K86) ;

If I wanted the chrome look I could go with the same fitting in chrome plated brass, (McMaster-Carr part # 5483T92) for a couple dollars more.
The Tygon tubing is very attractive price wise but as it only has a max pressure rating of 85 psi I think the
Crack-Resistant PFA Clear Tubing for Chemicals (McMaster-Carr part # 52705K32) would be a better choice;

I should be able to reuse the zerk, or for the shiny look add a few stainless ones (McMaster-Carr part # 1293K11).
Now for some
pinchclamps (McMaster-Carr part # 6541K34)
http://www.mcmaster.com/#standard-hose-clamps/=13x410z
Barbed fittings 17.44
Couplings 8.34
Tubing 27.50
Pinch clamps 8.84
Plus zerks if you don’t got nun.
Plus the pinch clamp tool if you ain’t got that either
Plus shipping
Enough to do 4 tractors.
