Clark Equipment Company in World War Two
Buchanan, MI (Currently Lexington, KY)

This page added 12-9-2017.

The Clark Trucktractor Company was formed Battle Creek, MI in 1919 as a division of the Clark Equipment Company whose main products were tow tractors and forklift trucks.  During WWII these were the main products provided to the US military even though Clark is more well known for the CA-1 Airborne Tractor it designed.  The majority of the CA--1s were built by other companies after the Clark plant building them was destroyed by fire after 13 units.

The Clark Equipment Plant in Buchanan, MI won the Army-Navy "E" Award two times during WWII.
The Clark Equipment Trucktractor Division Plant in Battle Creek, MI won the Army-Navy "E" Award five times during WWII.

Clark Equipment Company World War Two Production Statistics:  (13)CA-1 Airborne Tractor/Bulldozers, Clarkson 6 Tractors, Forklift Trucks

The Clark Equipment Company designed CA-1Airborne tractor/bulldozer.  The CA-1 was designed by Clark for use by airborne forces to be airlifted in to a battle zone by glider or C-47 aircraft.  Small enough to be airlifted in the CA-1 allowed army engineers to prepare a landing strip.    Author's photo from the Indiana Military Museum in Vincennes, IN.

This particular example has the Braden winch which allowed the tractor to be extracted when stuck in mud.  Author's photo from the Indiana Military Museum in Vincennes, IN.

This example of a Clark CA-1 airborne tractor/bulldozer does not have the winch attached.  Author's photo from the National Museum of the USAF.

How important were bulldozers to the winning of WWII?  Below are the thoughts of General Dwight D. Eisenhower and Admiral "Bull" Halsey.

Asked about the weapons used to win the war, Admiral Halsey offered:  "If I had to give credit to the instruments and machines that won us the war in the Pacific, I would rate them in this order:  Submarines first, radar second, planes third, bulldozers fourth."

A quote from "The Great Crusade" by General Dwight D. Eisenhower:  "Incidentally, four other  pieces of equipment that most senior officers came to regard as among the most vital to our success in Africa and Europe were the bulldozer, the jeep, the 2-1/2 - ton truck and the C-47 airplane."

Below is an prime example of why both General Eisenhower and Admiral Halsey both included the bulldozer in their list of important machines that helped win WWII.

On March 5, 1944 an airborne assault of thirty gliders landed behind enemy lines in Northern Burma in jungle clearing designated "Broadway."  Included in the landing were Clark designed CA-1 tractor/bulldozers.  Using the small bulldozers army engineers were able to prepare a 5,000 foot long runway within 24 hours which then allowed more troops and supplies to come by C-47.  Note the CG-4A glider in the background.

The airstrip has been cleared out to allow the arrival of C-47 cargo aircraft.  This particular aircraft was also cited by General Eisenhower in his list of important pieces of equipment during WWII.

The largest contribution of the Clark Equipment Company during WWII along with forklift trucks was the Clarktor-6 towing tractor or tug.  Production of the Claktor-6 began in 1942 and ended in 1966.  Author's photo from the National Museum of the USAF.
