Caterpillar Auto Patrol

There probably is a grader number on the frame of the grader that would help date it. Not sure if we can nail down the year even then.

The earliest listing by year, which I have, is the K series #10 and #11 Autopatrols from 1938-1941

Have fun! Post pics!

I show a 6H engine to be found in a 9F series chassis of 1936-1938 vintage.
Engine is a 4400G (same as a "30" (6G))

hello Eugene ,your grader number is from the engine making it fitted to a 10 atuo patrol .
some info - No 10 atuo patrol ,max hp=44 ,rpm=1400 ,No cly's=4 ,bore=4.25 ,
stroke=5.5 .
Being a low number i would say it was biult in 1933 (maybe),graders are hard to date
i will post some other info about your grader,post some pic if have any .i would like to see it ,hope the info helps,bruce oz

Thanks for the information. I will try to get some photos onto the site for everyone to see. Thanks, Eugene.
