You don’t see many crawlers at the shows around here. I suspect that is at least partly due to the logistics involved in moving them. Weighing in at a hefty 6130 pounds you can bet that it took more than a little effort to haul this Cat through the mountains to Gray, Tn. for the Tri-State Antique Power Association Show back in April.
The placard you see propped in the operator’s seat informs us that this is one of only 1185 4J series Caterpillar Model R2 units built between 1938 and 1942. The Antique Caterpillar Machinery Owner’s Club website ( www.acmoc.org ) places total R2 production at a slightly higher 2418 between 1934 and 1942. This website features a very detailed history of Caterpillar that is worth a look.
Built at the Peoria IL. plant in 1939 the 4 cylinder 251 cubic inch engine was rated at 25 hp. At the drawbar and 30 hp on the belt by Nebraska Test # 320.
This nicely restored example is part of the Christenbury Caterpillar Collection brought to the show from Liberty, NC.
