I've been trying to track down any transmission differences between the two transmissions. The ST110 has its transmission and nothing bragging about it on the decals. The 120 though has the words Eliminator on the decals and more, brags about a "Tiller Transmission". Perhaps it is the same transmission or maybe the 120 comes with a heftier transmission. If it does, maybe I'll make the 120 my keeper and sell the ST110 and the snowblower attachment as a pair.
I've put in at least 30 hours in hands on repair to the ST110 and it'll be a fine tractor for the leaves this fall. If the 120 has a better transmission I'll leave that in there and migrate engines. It does appear the PTO is toast in the 120. I hooked a good battery to it and turned on the PTO and the fuse fried instantly. Hopefully I can remove a locked up PTO, not sure how it attaches/works exactly but will do what I can.
Thinking seriously I should find an older one with a rear tiller run by gear, I'd like to have a garden again and really need a rototiller, it'd be nice to rehab an old tractor like a 1050 that is in mechanically excellent shape & comes with a rototiller attachment. That would be fun.
