I know there are several good forums devoted to the IH cub cadets... But I would be using this thing like I use my Scout, not restoring it... I'm asking my questions here 'cause this is a more practical community and I'd like the more practical answers to my questions: I'm moving to a ½acre property near Columbus, OH. I imagine I'll need to mow the grass weekly during the spring & early summer. This is new to me coming from Colorado... I know I don't want to buy a $1500 new throw-away mower. I damn sure know I won't enjoy working on a used throwaway mower... I like the look of the IH 70 & 100 models over the late 60's & 1970's models. I'm assuming I would enjoy working on one of these little tractors. I've rebuilt the SV 304 in my Scout so rebuilding anything on the cub should be more than manageable for me... BUT do these old mowers actually cut the grass fast enough to be worth it? Or would I be spending hours wrenching on the tractor every time I needed to mow only to spend hours more actually cutting the damn grass? Ideally this tractor will run well enough that my wife could mow the grass when I can't get to it. Is the only difference between the 70 and the 100 the size of the Kohler engine -- or are there other major differences to be aware of? Can the 12hp Kohler or some other newer engine be put in place of the 7hp or 10hp oem engine? Thanks for any insight and practical knowledge anybody can share.
