Farmall Cub

My SA with a snow plow on the front mount has a problem lowering. It raises ok, but when you go to lower it, it bounces all the way down, something like "pulsating" or quick bounces to describe it . I've drained the fluid , replaced it with new and ran out the air in the line, but doesn't do any good . Any other suggestions ??

Go to Rudi's manual server, and then to the Blue Ribbon manuals. The touch control manual there covers cub and Super A. It has a trouble shooting guide.

thanks John, looks like I have some tearing down to do !
