traded for a tractor and FEL is hooked to rear service remote. one line is plumbed to the in the other is plumbed to the out on the loader valve from the remote. When you push the service remote forward the loader functions properly only slow. When you pull the service remote back loader will only raise will not lower, will tilt one way but not the other. Never seen one plumbed this way. Could this be the reason loader works slow? Thanks
