I recently aquired a used 917.273320 Craftman garden tractor. It runs great and I have mounted a snow blower on it. Not sure what year it is.
I noticed that a hose on the hydro was deteriorating and dripping oil. I removed the hose and cut off the soft end and reattached. My problem is that I lost some oil out of it while I was working. I took the plug out and tried to add oil but it doesn't seem to take. The plug has some type of pin on it and there is a spring down inside the hole. Have I taken the correct plug out? Also what type of oil should I use?
