Hyd. drain for super 55

To drain the system lower the three point hitch by pushing the hydraulic control lever down so there will be no trapped oil in the internal hydraulic cylinder. Remove the pipe plug from the hydraulic passage cover in front of the operator's seat and install in its place a 1/4" standard piple nipple.(it's to the right of the filter you changed) Start the engine and let it run at an idle speed until the oil has peen pumped from the hydraulic system. To catch the oil as it is being pumped from the system, hold a container of at least three gallon capacity below the 1/4" pipe nipple which has just been installed on the hydraulic passage cover or install a hose on the pipe to carry oil from the pipe to a container on the ground. Stop the engine immediately when the oil ceases to flow from the system and reinstall the pipe plug. WARNING NEVER RUN THE TRACTOR ENGINE WHEN THE HYDRAULIC SYSTEM IS DRAINED.

If you have an external valve, remove the hoses from the couplings. Start the tractor and acutate the external valve in either the up or down position until the oil has drained from the system. Drain the oil from the external cylinder by working the piston rod back and forth in the cylinder by hand. Reconnect the hoses and fill the unit with 11 quarts of oil. Loosen the hose connected to the front port of the valve and pull the hand lever back. With the tractor engine operating at idle speed, hold the lever in this position until oil free of air escapes from around the threaded hose end. Tighten the hose. Loosen the rear hose and repeat this operation by pushing the hand lever forward. This will bleed the air from the system. After bleeding , check the oil level in the hydraulic housing.
