My hand crank would not engage into this tractor. My other two start easily with a couple of turns of the crank. Did IH change the design not to accept the hand crank for '59?
I'm not sure about a design change friend has a 61 lowboy & we can crank it.
There are three things that I have seen done so you cuold not crank it.
1. bolt in the end of the crank for some reason (person there before you was afraid pully would fall off).
2.Ears that let the crank engage broken off (don't know how this could be done but I have seen it after the fact).
3. Pully is either a after market or I think some of the newer cubs late 60 to 70's did not have a crank.
john or bigdog might shed more light on this last.
