International 510 Payloader

Older machine we use at lot to load material. Runs good and works just fine. Updated to a newer machine. Heater works. Has 3rd valve but Ive never used it for anything. I bought it 2 yrs ago and transmission had been rebuilt at college in Nebraska. Ive had no issues with that. Starter is getting rebuilt. I had front cylinders redone last year. Thats about all I know.
