Dixon ZTR560 commercial

I recently picked up a basket case 560 from the local scrap dealer who was getting ready to cut it up. Paid $100 and think it will run again after some tlc. It has a Kohler 20hp magnum motor that needed some work, but should run. Just got done cleaning the carb and removing the biggest mouse nest I have ever seen. New plugs, ignition module, oil and filter, starter brush kit, fuel line, and we should be good.

Does anyone know if Dixon had a service manual for this machine? I have an owners manual and parts list for it but would like a shop manual if there is one out there. Thanks fellas. Will try and post a pic of the machine.
