ENGINE DETAIL
The Twin City 17-28 tractor features a liquid-cooled, 4-cylinder kerosene engine with a displacement of 340.5 ci, ensuring efficient thermal management and extended operation times. With a bore and stroke of 4.25x6.00 inches, it excels in torque output at a low rated RPM of 1000, making it suitable for heavy-duty agricultural tasks. However, the use of kerosene may pose challenges in cold-start scenarios, thus requiring adequate pre-warming or alternative fuel considerations for optimal performance.

TWIN CITY 17-28 ENGINE
The Twin City 17-28 tractor is equipped with a 5.6L 4-cylinder kerosene engine, which offers efficient fuel combustion, ideal for agricultural tasks requiring consistent power output. Its 30-gallon fuel tank provides extended operation between refuels, though the small auxiliary fuel tank (1 gallon) may limit versatility in field conditions. This tractor is well-suited for continuous cultivation or plowing, but users should monitor kerosene levels closely to avoid interruption due to the auxiliary size.

TRANSMISSION
The Twin City 17-28 tractor features a simple gear system with 2 forward and 1 reverse gear, which enhances maneuverability in both field and transport operations. Its dry disc clutch offers reliability but may require more maintenance compared to wet clutches, particularly in heavy-duty applications. This configuration is optimal for small to medium-scale farming tasks, ensuring easy operation but may limit speed versatility for larger-scale operations.

MECHANICAL
The Twin City 17-28 features a 4x2 2WD chassis, offering basic traction suitable for light to moderate field work but may struggle in soft or uneven terrain. The manual steering system provides direct control, although it may require more physical effort, particularly in tight maneuvers. The 2-speed gear transmission allows for limited versatility in speed adjustments, making it ideal for tasks that don't require frequent gear changes but potentially less adaptable for more complex operations.

TWIN CITY 17-28 TIRES
The Twin City 17-28 tractor features steel orchard wheels with a front size of 30x5.75 and a rear size of 42x12, optimizing stability and traction in orchard applications. The dual-wheel configuration enhances its ability to navigate narrow rows while providing adequate load distribution for fruit harvesting. However, the steel wheel design may present challenges in soil compaction and operator comfort compared to pneumatic alternatives.

DIMENSIONS & TIRES
The Twin City 17-28 tractor's relatively short wheelbase of 84 inches enhances maneuverability, making it suitable for smaller fields and tight spaces. Weighing between 4600 to 5350 pounds provides a balanced foundation for stability during operation, particularly in plowing or heavy tillage tasks. The larger rear tires (50x12) offer improved traction and flotation in soft soil conditions, while the smaller front tires (34x5.75) may present challenges in rough terrain navigation.
