ENGINE DETAIL
The Twin City 12-20 tractor features a 4-cylinder liquid-cooled kerosene engine with a substantial displacement of 340.5 cubic inches, providing adequate torque for heavy-duty tasks while operating at a low rated RPM of 1000, which enhances fuel efficiency. Its hand-crank starter may present challenges in ease of use, especially in colder conditions, while the coolant capacity of 28 quarts allows for effective temperature regulation during prolonged operation. This tractor is well-suited for agricultural applications requiring reliable performance in moderate load conditions but may not be ideal for rapid startups or high-speed tasks.

TWIN CITY 12-20 ENGINE
The Twin City 12-20 tractor is powered by a 5.6L 4-cylinder kerosene engine, offering efficient fuel performance for agricultural operations. With a primary fuel tank capacity of 23 gallons and an auxiliary tank of 3 gallons, it allows for extended operational periods, reducing downtime for refueling. However, the reliance on kerosene may present challenges in terms of fuel availability and handling compared to diesel or gasoline alternatives.

TRANSMISSION
The Twin City 12-20 tractor features a basic transmission system with only two forward gears and one reverse gear, which may limit operational versatility, particularly in demanding tasks. This simplicity can be advantageous for straightforward applications, potentially resulting in reduced maintenance needs. However, the lack of multiple gear ratios could pose challenges in navigating varied terrain or optimizing power for specific tasks, making this tractor better suited for lighter, more uniform operations.

| Gears | 2 forward and 1 reverse |
MECHANICAL
The Twin City 12-20 tractor features a 4x2 2WD chassis, which provides good traction for light agricultural tasks but may struggle in uneven terrain compared to 4WD options. Its manual steering can offer simplicity and ease of maintenance, although it may require more physical effort, especially during prolonged operation. The 2-speed transmission allows for basic speed adaptability, but operators may find it limiting for varied field conditions requiring more precise gear selection.

TWIN CITY 12-20 TIRES
The Twin City 12-20 tractor features an Ag front tire size of 34x5.75 and an Ag rear tire size of 50x12, both in steel construction, providing durability and reduced wear on rough terrains. The larger rear tires enhance traction and stability during agricultural tasks, while the narrower front tires offer better maneuverability in narrow rows. However, the all-steel tires may lead to increased weight, potentially affecting fuel efficiency and compaction on softer soils.
