Bought tractor in summer of 1999...bucket has always gone up fine. I always thought it went down slower than it should but things were working so I left it alone. Bucket started going down slower and slower over the years...hard to back track to a time line, but the more I think about it am pretty sure it really got worse when I blew that hose and put that quick disconnect in because I remember being concerned that it might be a result of getting air trapped in the system and I needed to bleed it off some how....never did figure out how to do that other than leaking some/fluid and air out of the furthest fitting from the controller.
I think you may have hit the nail on the head....perhaps getting rid of the quick disconnect AND rebuilding the controller are the answer. Controller has the horizontal lines of the Gresson 300 that was mentioned, need to remove a half inch of paint to see if I can find any other marking so I can get a diagram and rebuild kit... Wow, this is great..sure wish I could get on this ASAP, but have some medical stuff scheduled for this week...going to be a long week waiting for tests results AND waiting to check out this theory on the dang thing...thanks for the second, third, fourth, fifth, etc., sets of eyes and all the recommendations...sure know a whole lot more about hydraulics than I when I started out. Thanks a lot to all, will let you all know the final chapter.....

Today's Featured Article - Madison's County - by Anthony West. Philip Madison has been a good friend of mine for quite some time. He has patiently suffered my incessant chit chat on the subject of tractors for longer than I care to remember, and on many occasions he has put himself out, dropped what ever it was he was doing, to come and lend a hand cranking handles, or loading a find onto a trailer. Although he himself has never actually owned or restored a tractor, he was always enthusiastic and always around helping with other peoples projects.
