Good day, I purchased a 790 with a frame-mounted backhoe (Model 7) and unfortunately it did not come with a 3 pt hitch. I'm trying to buy a used three pt hitch but not having much luck. There are a few after market hitches available but I'm not sure what size lift arms or side links I would need. Can anyone with a factory set-up provide the sizes (lenght) of these parts? Thanks for you help.
