A big thank you to Nathan and all the folks that helped put together the Grader Manual. Lots of interesting photos of machines in operation too.
As a minor side note page 15 is blank in my book and not sure if it intended or a misprint. Still a great reference book. Price is very reasonable at $20 in the ACMOC Store.
