OK, I have to ask because sometimes it is the simple, most obvious things that get overlooked. Is the PTO Lever Engaged? Is the oil level up? Is the oil water contaminated? There is a gasket on the top cover that you sit over, BUT that isn't the problem. Your hydraulic cylinder has either three steel rings OR a rubber O-Ring as 'seals' in the cylinder, and the latter uses a leather backup washer/wiper as well, depending on if it was ever switched over to the NAA style. The pulsating effect you describe is a sign the chambers are clogged and possibly the entire system needs a good cleaning and/or rebuild. Do the leaking cylinder test to determine if cylinder and piston are worn out. There is a pretty good chance the system was never serviced before, and if so, maybe a long time ago. Use this document as a reference guide -see LINK.
