[quote=&quot;John Schwiebert&quot;:20u8r8rq]Well we are here to help you, but for me I need more information from you. First of all there were many changes in the hydraulic system so a serial number of the tractor would help to start with. How much oil do you have in the transmission &amp; final drive?  Does the 3 point go up and down when cold? Start there first[/quote:20u8r8rq]

Thanks for your reply, John.
    It's a 1955 Super 55, S/N:13,142-518. When I serviced the tractor this spring, I put in the specified amount of 90 weight, per the manual, 5 gallons. I put in the Hygard hydraulic fluid until it showed full on the dipstick, but the 3 point was not raised when I did this, and checked the fluid level. 
On my tractor, the hyd filter housing is on the side, not the front, like on the later 1957 models like Chris Losey's Super 55.
I will go out now, and check the Hyd level with the 3 pt. raised, and check its operation when cold. 
I was hoping when it sat for awhile, that maybe the air got out of the fluid if any was in there....
