The orifice in your safety/pressure-control valve block is plugged. Your system is consequently continuously loaded and putting that load on the tractor engine. When you move one of the control valve handles you give the hydraulic fluid somewhere to go (to the cylinder controlled by that valve), rather than forcing it to go through the high-pressure safety valve.
This is a pretty common problem for these systems. You'll need to pull the valve block and clean it, especially the orifice in the control circuit. This problem may mean your entire hydraulic system needs to be cleaned out, also.
