Picked my tiller up today, to dark to look for numbers tonight. I will look tomorrow. I have a sneaking suspicion that I am missing a part. There are two pullies on the tiller its self. I think there is a piece that goes under the tractor that would fit in where the mowing deck fits to position the belt under the belly of the mower. If I don't have that is it hard to find and is it going to cost me an arm and a leg to get? I have a feeling I don't want to ask that. My dad is a master welder is there something out there that would have the specks he also specializes in bule print reading and fabrication. I will post up the #s tomorrow if I can find any, any suggestions on where to look for the #s on the tiller?
