    580B mystery gear

    I found it in the torque tube housing. I'm going to assume it's leftover from a previous repair or someone accidentally dropped it in there at some point because I've found nothing.

    Case backhoe interchange

    I feel like I've come across an answer to this before, but no manner of searching has turned up what I am looking for. I have been trying to find a backhoe attachment to fit a 580B -- model 35, I assume. When I bought the tractor a few years ago, it had a counterweight instead. I haven't been...
