This TA series McCormick-Deering tractor was built by International Harvester in the early 1930s. The cab is shaped like one from an old locomotive.

This is old but I can’t tell when it is from – maybe the 1930s or 40s. At some point the owner bolted a perforated steel plate over the radiator to protect it from damage. Many of the machines at the museum were similarly equipped, which suggests how hard logging could be on equipment.
