Case 300
Utility tractor · 1956–1958 · Diesel
The Case 300 was a general-purpose utility tractor produced from 1956 to 1958, marking Case's move into diesel power with a Continental GD157 4-cylinder engine rated at roughly 22 drawbar and 27 belt horsepower. Only 249 units were built, making it one of the rarer models in Case's numbered-series lineup, offered with either a 4-speed or optional 12-speed transmission. It represented a transitional design bridging Case's earlier letter-series tractors and the more standardized 400/500 series that followed.
