504 had the correct answer. I thought I had checked the free float pin but I apparently looked at the incorrect slot. Either the pin had come out or was never there in the first place.
Here’s how I found the answer.
I backed up to my old Caprice and stuck the fast hitch under the rear bumper. The fast hitch raised that ol’Chev 2 ft off the ground like it wasn’t even there. I shut down the tractor and let it set for 15 minutes and it didn’t sag an inch, so I knew the pump and screen are good and no leak in cylinder or valve. But I still could not raise the rear of the tractor with the fast hitch down pressure.
So I thought I would switch around the hoses on the cylinder to see if it would make a difference. Luckily, the debris guard and the seat had to come off to get to the cylinder hose connections and it was too cold to mess with all that.
I put a block under the fast hitch and ran it up and down watching it. I noticed there was a hesitation in the movement and as the hitch touched the block the hitch stopped but the cylinder kept moving. Bingo! The lightening bolt of enlightenment!
I remembered “504” stating that the pin might be missing allowing the hitch to free float. I had checked that pin but on watching the hitch move I saw that I had checked the wrong hole and the float pin was indeed MISSING.
After I placed a hitch pin in the correct hole the fast hitch raised the rear of the tractor with no effort at all. And a good thing too, I found I had a broken cross link on my tire chains to repair.
Several times on this forum I have given the advice to start from the beginning, checking all the basics first.
I guess I needed a reminder to take my own advice.
Thanks to all for sharing good advice and especially 504 to “check the basics first”

Today's Featured Article - The Cletrac General GG and the BF Avery A - A Bit of History - by Mike Ballash. This article is a summary of what I have gathered up from various sources on the Gletrac General GG and the B. F. Avery model A tractors. I am quite sure that most of it is accurate. The General GG was made by the Cleveland Tractor Company (Cletrac) of Cleveland, Ohio. Originally the company was called the Cleveland Motor Plow Company which began in 1912, then the Cleveland Tractor Company (1917) and finally Cletrac.
