I've had the tractor for 6 months. Plowed snow with it all winter. Great tractor! The steering box works like a new one, and I would like to keep it that way. I have been searching the archives and found several references to draining the steering box. The parts manual shows only one plug, and it is at the top of the box. Is there a way to drain the box without removing it from the tractor? I hope I don't have to remove a perfectly good box just to change oil in it. Am I missing something? ( Good possibility!) Thanks, Larry
