The Model Twenty was the first product designed and built by Caterpillar that was not a carryover from Holt or Best.
It was introduced in 1927 in San Leandro, California then began production in East Peoria a year later.
Harmon Eberhard, an engineer for Holt and later became President and Chairman of Caterpillar, helped design the Twenty.
