The Allis-Chalmers HD-14 diesel crawler is shown from the rear inside the tractor test lab. Carlton Zink stands beside the belt pulley to measure drive pulley speed with a handheld tachometer. The driven pulley speed on the dynamometer and the torque exerted by the tractor are measured on the dynamometer. John "Jack" Neumann, a company rep, in the white shirt, and Professor Hurlbut are seated in the right foreground, watching the test.
