John Deere’s Armored “A”

This project was inspired by an article in the September-October 1993 issue of Two Cylinder magazine. The article covered John Deere’s World War II effort which included the submission and testing of an armored version of a Model “A” tractor. The armor-plated farm tractor with two hydraulic operated turrets was to be used as:

• 1. A combat unit
• 2. An armored prime mover, or
• 3. A trainer for Tank operations.

The testing was conducted at the Aberdeen Proving Ground in Maryland in January of 1941 but was found to be unsatisfactory for military operations and all operations ceased. The article concluded with – “and it is now up to a dedicated enthusiast to replicate the historic war wagon”.

The tractor used for the project was a 1947 “A” owned by William J. Wideman (Great Grampa) and built by William D. Wideman (Grampa), William J. Wideman (Son) and William B. Wideman (Grandson). The build began in March of 2018 and went to the first tractor show in July of 2021.

There is only limited information (pictures), so this build utilized only the few available pictures for scaling and proportions. There are no known remaining examples of the original prototypes. All fabrication sketches and drawings for this project were developed using the 38-inch rear wheels as a reference point. The steel sheet (10 ga.) that was used is much thinner than the plate used on the actual prototype to reduce weight. All parts other than bearings and hydraulic hardware were shop fabricated.

We didn’t keep any count of hours and dollars, but both were sizable! During operation you need a ground guide (poor visibility) and a good hearing protection (loud inside)!
