The Allis Chalmers HD10 is a crawler tractor, featuring a General Motors 4-cylinder blower diesel engine with a liquid cooling system. This tractor is designed to minimize ground pressure, distributing its weight across a larger area for enhanced stability and minimal soil compaction. The engine delivers power through a sliding gear transmission with 6 forward and 2 reverse gears. With an engine displacement of 284 cubic inches and operating at a rated RPM of 1600, it stands as a testament to the robust industrial machinery of its era. The HD10's track system and a ground pressure rating of 7.16 psi make it suitable for a wide variety of tasks where traction and balance are crucial.
