i was learning how to run a scraper,{631c} and had the privileage of pulling in front of a growly old timer, he wasnt a very big guy but he loked mean sitting in the h, {solid dozer} if i didnt pull in right, wam, all day long seemed like i didnt do a thing right, im sure the stinger on that 31 was about a foot shorter than when i started running it. he called me and this other kid the fresno twins. after i started to do better we got along alot better, one day i finally asked him what a fresno was, he said it was the first scraper ever made and he could move more dirt with a fresno than i could with the 31. after i finally seen a fresno i realized the joke. has anybody ever moved dirt or have pics of a fresno?
