ENGINE DETAIL
The Keck-Gonnerman 25-50 tractor features a 606 ci (9.9 L) LeRoi kerosene-powered engine, which provides significant torque, suited for heavy-duty agricultural tasks. Its hand-crank/electric starter system offers versatility, though the hand-crank may pose a challenge for user convenience. Overall, the tractor's large bore and stroke dimensions enhance its power delivery, making it advantageous for demanding soil cultivation, but may increase maintenance requirements due to higher vibration levels.

TRANSMISSION
The Keck-Gonnerman 25-50 tractor employs a simple gear mechanism with 2 forward and 1 reverse gear, offering basic maneuverability suitable for smaller agricultural tasks. Its limited gearing may pose challenges in hilly terrains, leading to potential power loss during heavier operations. However, the straightforward gear system can also simplify maintenance and operation for novice users.

MECHANICAL
The Keck-Gonnerman 25-50 features a 4x2 2WD chassis, suitable for relatively flat terrain but limited in off-road capability due to the lack of all-wheel drive. The manual steering and open operator station, while simple and cost-effective, may reduce operator comfort during prolonged use and expose the operator to adverse weather conditions. Its 2-speed gear transmission allows for basic versatility in speed management, though it may not provide the same efficiency or ease of operation as modern hydraulic or automated transmissions found in contemporary tractors.
