From what I've read, the Jubilee / NAA is pretty different hydraulics
wise from an 8N. I know they did away with the three engine style piston
rings and replaced them with O-rings and a leather wiper which is now
replaced with a rubber wiper. Isn't the Jubilee / NAA when the lift
position control and draft control showed up vs. basic manual up/down
control?

You found a hole in my old ford knowledge. My NAA is the backhoe
tractor. While I've had this tractor and used it hard for over twenty
years, I've never once had need for the tractor's hydraulic system.
Sounds like your NAA is the same as the lift assembly on the Ford 860
with the exception of no leather.

I'm glad to see you don't have the 8N lift. Not one of ford's best
designs. But, keep in mind, ford was the first tractor made with a
true three point system.

The NAA uses the O-rings and wiper like the later 600 and 800 series.
Also has the better draft control.

Ford didn't design the three point they used. It was Harry Ferguson who
developed a working 3-point. Ford had a handshake deal to use the system
and then refused to pay for them once he started selling tractors.

Harry opened his own factory in England and the TE-20 was the result.
Then he opened a plant in the US and the TO series was born. This was
direct competition to Ford.

I have owned most of both sides of the isle. Ford 8N, 9N, 2N, a 600 and
800 series, plus a couple TO-20s, a TO-35, 35 Deluxe and some of the
larger ones as well. Most were good tractors if you used them in the
envelope they were intended for.
