Thanks everyone for the info and tips so far. The only attachment that came with the tractor was the snow plow, but I would also really like to find a mower deck, just don't exactly know where I would look to find one. I'm also working on finding the weights and chains for it for the winter.
Glad to see there are a decent number of other tractors like mine out there, and hopefully mine can be in the same shape as some of yours one day.
I have a spare mower deck you can have. Its missing the center spindle but the rest is there. I can take a look at it tonite and grab a couple pics. I just moved it out to my "what the heck am I going to do with this" pile. Where in MI are you located?
