"Drain the hydraulic system every spring and fall. 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 operators seat and install in its place a 1/4 inch standard pipe nipple. Start the engine and let it run at an idle speed until the oil has been 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."

I posted this before and someone actually told me I was cracked. I swear if there is another way please educate me.
