    Hydrostatic Transmission Check on a 963 or 973.

    Hydrostatic Transmission Check. I’m looking to buy an eighties 963 or 973 with a Hydrostatic Transmission. I have never driven a Hydrostatic Transmission. What are some ways to check it out? How would one tell if it’s going bad or is good? Best Regards, Steve Z.

    Cat 963 vs 973 vs 983, Which to Purchase?

    Thank you for the input. Seems both of these sellers may not have their facts right. Instead of spending the day in my car driving to see these, I’m going to work in my yard. It will be much more satisfying. Again thanks.
