I am a newbie to both this site and case tractors. I recently purchased a 1941 Case SC and was hoping someone could help me with information about it. Where do I get manuals on this tractor? What should I look for as normal problem areas. It still has the 6 volt starter system on it and I know nothing about them so any advise would be welcomed. Also it has some kind of 2 point hitch on it that I have never seen before. It works throuhg the PTO and will go up and down when a small pedal is pushed that is below the seat. It seems to work well but I didn't know if this was original and what it would be used for. The tractor seems to run well and have decent tires with normal wear on the paint. It was recently tuned up and as soon as I get it home I intend to change the oil. what weight oil shold I use?
