Inland Steel & Foraging snow blower DA102 parts look up

Today we broke a rod 1 3/8", 21 spline. Which connects to the tractor’s PTO and goes through the snow blower. First question. Who has the part for sale? Does anyone have a manual so we can see specs and a part number of this part? Is there service support for Inland Steel and foraging?

You could go onto Ebay, Craigslist, or Tractorhouse
