I have a 24 ton splitter 3pt hitch runs off the tractor hydraulics, originally it had a valve on it but the seals blew out of the valve shortly after we bought it. I took the valve off and run it off the remotes using the tractor valve,have to run the tractor at pto rpm and it's still slow also heats the oil. I've checked the inlet to the cylinder didn't see any restrictor. I tried it on both tractors and at this rpm both loaders are very fast so I don't think it's a flow problem. Can there be something in the cylinder to make it so slow?
