I have a New Holland TC29 with a 7308 FEL rated to pickup 875 pounds with the loader arms and 1602 pounds with the curl. Today I unloaded a pallet that weighed 837 pounds and the main loader cylinders just handled it OK, but I noticed that the curl cylinders couldn't budge it at all. The curl cylinders have always been way stronger than the main loader cylinders until today. I'm guessing I have a problem in the loader valve. I'd appreciate any insights any experienced hydraulic techs might have before I start getting into it.
