Overview

Manufacturer

John DeereReference

339 distillate 3-speed 2WDMay 4 - 15, 1931Link: Nebraska Tractor Test 190 fileReference

Introduced at S/N 402040 in July of 1930. The new engine had a larger bore with lower compression. It had slightly more power with better fuel economy. The lower compression eliminated the pre-ignition problem when using low-quality fuel, so the water-injection system was eliminated.Reference
