Brand new to forum but really need some help figuring out a tractor problem.
I own a Ford naa and it is a great tractor but I can稚 keep the lift arms down when I speed the tractor up, unless I have quite a bit of weight on it ?
Also own a Ford 600 working on.

Do you still have the OEM pump on your NAA, or have you or someone else put a pump on it from a 600 + series. Your exhaust valve is rated for a max of 2.9gpm, the later pumps can make 4gpm... that will make the lit arms tend to rise unless weighted. If you have the older square vane pump and the hyd flow control, try turning it down a bit.

Also, if your oil is dirty and watery, it will not pass thru the exhaust valve as easy.

If you have heavy gear oil in the hyds that can cause issues too. I like to use UTF fluid instead.
