Hercules, like its independent competitors, was left trying to increase future government and military business to increase sales. The automakers now produced their own mills, and this included some of the specialty makers like Caterpillar and International Harvester.

Hercules engineers, however, set out to model their diesel line utilizing the same principles from their successful gasoline-powered mills.

Diesels were too big, bulky, and considered too heavy for portable applications.

Stationary units and marine users comprised the bulk of this early market. In 1931 Hercules engineering started looking at the modern and novel compression ignition engines at the time, diesels were considered to be limited in their applications.
