Classic Machines: Caterpillar's 631B scraper

[@lewiemcneely9143]

I don't remember what series the 631'a were I fooled with but they were pony motor start, round fenders and no floating gooseneck or cab of any kind. But they were still fun to run. I swapped out to get a breath from the 8-H with no cab doing the pushing but it was always short lived. The pan guys liked the air too. Thanks, Lads! Tough machines!
