I had a 560 farmall with the same problem. I had an older loader on the tractor. It would lift fine. When I updated to a newer quick-tach loader it wouldn't lift big bales. I had to get larger diameter cylinders. The older loader had more mechanical advantage than the newer one. These old farmalls operate at only 1200-1350 PSI, as opposed to most newer tractors which operate at 1900-2150 PSI. You can up the pressure by placing washers under the relief valve spring, but this is a good way to create other problems. The other possibility is a bad pump. Go to your dealer and buy a high pressure gauge. Screw a hydraulic coupler tip to the guage and plug it in to your remotes. Pull the lever back, if it doesn't read at least 1100 PSI, you probably need a new pump. GOOD LUCK!
