Find a Gallion 503 & put a diesel in it from an IH combine like myRight now I am looking for a small cheap grader to keep my driveway in shape. Something like an old Deere 570 would be perfect. However, I certainly wouldn't refuse to consider a larger machine, if one became available at a good price. I wouldn't even turn down something absurdly large like a Cat 24. I would look at it as a challenge (grading a small 2,200' driveway with a huge machine), and sort of an adventure.
Sometimes a good deal can be had on something like that, simply because most other people wouldn't even consider it, and if it is an older machine, most businesses aren't interested.
Grandfather & dad did in 1992.
Cheap & a great little grader.
