ENGINE DETAIL
The Advance-Rumely 6A tractor features a Waukesha 6-cylinder gasoline engine, offering a substantial displacement of 404.3 cubic inches (6.6 liters) which supports robust torque production, ideal for heavy agricultural tasks. Its liquid-cooled vertical L-head design ensures consistent operating temperatures, enhancing reliability and longevity in demanding conditions. However, with a rated RPM of 1365, the engine may lack the high-speed performance desirable in certain applications, making it better suited for low-rev, high-torque tasks, such as plowing or heavy lifting.

ADVANCE-RUMELY 6A ENGINE
The Advance-Rumely 6A tractor features a Waukesha 6.6L 6-cylinder gasoline engine, providing robust power but potentially lower fuel efficiency compared to diesel counterparts. Its 25-gallon fuel tank allows for extended operational periods, beneficial for large-scale tasks. However, users should consider the limited torque output typical of gasoline engines when tackling heavy-duty fieldwork scenarios.

TRANSMISSION
The Advance-Rumely 6A tractor features a combination gear transmission with 6 forward and 2 reverse speeds, enhancing versatility and maneuverability in diverse agricultural tasks. The gear selection facilitates optimal power delivery for both traction and speed, making it suitable for various implements. However, the limited gear options may present challenges in navigating steep terrains or performing in extremely variable field conditions, requiring careful operator skill to maximize efficiency.

MECHANICAL
The Advance-Rumely 6A tractor features a 4x2 2WD chassis, providing adequate traction for light to medium-duty applications, but may struggle in hilly or muddy terrain due to its lack of all-wheel drive. The manual steering can enhance operator control at low speeds but may lead to fatigue during prolonged operation, especially without a cab for shelter. The 6-speed transmission offers versatility in speed selection, making it suitable for various tasks, though less efficient for operator comfort compared to modern automatic transmissions.

ADVANCE-RUMELY 6A TIRES
The Advance-Rumely 6A tractor features a robust steel construction with a 30x6 front wheel and a larger 48x12 rear wheel, providing enhanced traction and stability in various agricultural applications. The steel wheels offer durability but can lead to increased soil compaction, which may affect crop yields in sensitive soil conditions. Ideal for heavy-duty field work, this configuration maximizes power transfer to the ground, making it suitable for pulling larger implements.

DIMENSIONS & TIRES
The Advance-Rumely 6A tractor, weighing 6,370 lbs (2,889 kg), features a robust tire configuration with 30x6 front tires and 48x12 rear tires, enhancing traction and stability on varied terrain. This tire size combination is advantageous for plowing and heavy-duty applications, allowing for better weight distribution and reduced soil compaction. However, the relatively large rear tires may pose challenges in tight maneuverability, making it less suitable for smaller agricultural fields or densely planted crops.
