Hi, I am in Australia. I've just joined the forum because I love old machinery. We have a Caterpillar Grader that was in an old shed on our cane farm until a Cyclone blew the shed away 20 years ago. Since then it has been sitting out in the weather, allthough its relatively good shape.
I am thinking about restoring the grader, but I can't seem to find too much information on it. It has a Power Kerosene engine, the serial number is 6h36 and it has a single drive. The engine was running when parked up, but its now seized.
If anyone knows what model grader it is, and what year I would appreciate it, Thanks, Eugene.

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!

D2-5J's, D6-9U's, D318 and D333 power units, 12E-99E grader, 922B & 944A wheel loaders, D330C generator set, DW20 water tanker and a bunch of Jersey cows to take care of in my spare time😄

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))
