ENGINE DETAIL
The Twin City 21-32 features a robust 4-cylinder liquid-cooled engine with a displacement of 381.7 ci (6.3 L), providing efficient operation especially in cold climates where kerosene fuel is advantageous due to better cold start performance. Its bore and stroke dimensions (4.50 x 6.00 inches) indicate a torque-oriented design, making it suitable for heavy-duty tasks such as plowing and hauling. However, rated at 1075 RPM, it may lack high-speed capabilities, limiting its effectiveness in applications requiring rapid transport or fieldwork.

TWIN CITY 21-32 ENGINE
The Twin City 21-32 features a robust 6.3L 4-cylinder kerosene engine, providing efficient fuel combustion suitable for heavy-duty applications. The 30-gallon fuel tank offers extended operation time, while the auxiliary 4-gallon tank can be utilized for starting or backup during longer tasks. A key advantage is its relatively high power-to-weight ratio, but users should be aware of potential challenges with fuel availability and combustion characteristics compared to diesel engines in rural settings.

TRANSMISSIONS OVERVIEW
The Twin City 21-32 tractor features a robust 2-speed and 3-speed gear system, enhancing versatility for different agricultural tasks. The 2-speed system allows for quick adjustments between low and high speeds, while the 3-speed gear setup provides additional functionality for varying load conditions. This dual-gearing system can be advantageous in applications ranging from tilling to hauling, but may pose challenges in maintenance due to the complexity of the gear train.
| Description | 2-speed gear/3-speed gear |
TRANSMISSION 1
The Twin City 21-32 tractor features a unique [-|-] gear type with a simple transmission setup comprising 2 forward gears and 1 reverse gear, which may limit its operational versatility compared to tractors with more gears. The dry disc clutch offers minimal slippage and efficient engagement but may require more maintenance than hydraulic clutches, particularly in dusty agricultural conditions. Ideal for light to moderate tasks, this tractor’s straightforward design may benefit small farms or less intensive applications but could pose challenges for heavier workloads where a more robust gear range is advantageous.
| Type | gear |
| Gears | 2 forward and 1 reverse |
| Clutch | dry disc |
TRANSMISSION 2
The Twin City 21-32 tractor features a three-speed forward and one-speed reverse gear configuration, allowing for versatile operation across various agricultural tasks. The compact gear set enhances maneuverability on smaller fields but may limit speed on extensive, open terrains. Overall, this configuration is ideal for specialized tasks requiring precision rather than high-speed performance.
| Type | gear |
| Gears | 3 forward and 1 reverse |
MECHANICAL
The Twin City 21-32 features a 4x2 2WD chassis, which offers simplicity and ease of maintenance but may limit traction in varied terrain compared to 4WD alternatives. The manual steering provides a direct driving experience, ideal for experienced operators but may require more physical effort. With a 2-speed gear and 3-speed gear transmission, it offers flexibility for different speed requirements; however, the lack of an automatic transmission may reduce convenience during extended use.

TWIN CITY 21-32 TIRES
The Twin City 21-32 tractor features robust Ag tires, with a 34x5.75 size in the front and a larger 50x12 in the rear, allowing for enhanced traction and stability on uneven terrain. The steel construction of both tire sizes provides durability, although it may result in a harsher ride compared to rubber alternatives. Optimal for heavy tillage and pulling operations, the tractor's tire specifications suggest excellent performance in agricultural scenarios, practical for both row cropping and larger field tasks.
| Ag front | 34x5.75 (steel) |
| Ag rear | 50x12 (steel) |
DIMENSIONS

DIMENSIONS & TIRES
The Twin City 21-32 tractor features a compact wheelbase of 84 inches, providing enhanced maneuverability in tight spaces, making it suitable for small to medium-sized farms. Weighing 5,880 lbs, it delivers significant traction for pulling heavier implements, although this weight might challenge transport on narrow paths. Its tire configuration, with a narrow front tire (34x5.75) and substantially wider rear tire (50x12), offers a good balance for stability and reduced soil compaction in various agricultural fields.
