Well, the mowing seasons over, and I have to do some much needed work on my Mom's 1970 112. Tune up, fix the carb,rebuild the deck, and replace all belts. Any other things I should look into on this tractor? Anything that wears out, that I may mis? Until the last few years, it has seen varry little mantance sence we got it.[late 70's] Any tips for me? I have the owners manual[somewere, have to find that] but no shop manual. Think I will need one? Thanks for any help.
