ENGINE DETAIL 1
The Ferguson TEA-20's 1.9L, 4-cylinder gasoline engine has a relatively low displacement, making it suitable for light to moderate agricultural tasks, boasting a rated RPM of 2000 for efficient power delivery. Its oil bath air cleaner offers superior filtration for dusty environments, though maintenance requirements may increase due to oil changes. A potential challenge is the 6-volt starting system, which may limit operational reliability in colder temperatures compared to modern 12-volt systems.

ENGINE OIL
The Ferguson TEA-20 has an oil capacity of 6 quarts (5.7 liters), which is relatively low compared to modern tractors, making regular oil changes crucial for optimal engine performance and longevity. With an oil change interval of 120 hours, operators should monitor usage to ensure timely maintenance, preventing potential engine wear. Regular checks and adherence to the schedule can enhance reliability, though the compact size may limit oil reserve for prolonged tasks without frequent servicing.

ENGINE DETAIL 2
The Ferguson TEA-20 features a standard gasoline 4-cylinder engine with a displacement of 2.1L, delivering 28 horsepower, which enhances its capability for light agricultural tasks. Its bore and stroke of 86 x 93 mm optimize the torque curve for versatile use, while the 6/12V starter option provides flexibility in power systems. A challenge may arise from parts scarcity due to its age, but its simplicity and reliability make it a great choice for vintage enthusiasts or small farm operations.

FERGUSON TEA-20 ENGINES
The Ferguson TEA-20, equipped with a standard 1.9L or 2.1L 4-cylinder gasoline engine, strikes a balance between power output and fuel efficiency, making it suitable for light agricultural tasks. With an 8-gallon (30.3L) fuel tank, operators can expect moderate working duration before refueling, reducing downtime during operations. However, the gasoline engines may present challenges in terms of fuel availability and cost compared to diesel alternatives, especially in extensive farm operations.

TRANSMISSION
The Ferguson TEA-20 features a 4-speed unsynchronized transmission, which can present shifting challenges, particularly when transitioning between gears under load. This system offers simplicity and reliability, making it suitable for light agricultural tasks in flat terrain. However, operators might need to be cautious with gear changes to avoid damage and ensure optimal performance in more demanding scenarios.
| Type | unsynchronized gear |
| Gears | 4 forward and 1 reverse |
MECHANICAL
The Ferguson TEA-20 features a manual 4x2 2WD chassis, making it suitable for light to medium-duty farm tasks but may struggle on uneven terrain compared to 4WD options. The unsynchronized 4-speed transmission requires skill for gear changes, which can be a challenge for less experienced operators. Additionally, the open operator station offers good visibility for fieldwork but lacks protection against the elements, making it less ideal for extended use in adverse weather conditions.

FERGUSON TEA-20 TIRES
The Ferguson TEA-20 tractor features a front axle with 4x19 agricultural tires and a rear axle with 10x28 tires, providing a balanced weight distribution and suitable traction for various farm tasks. The larger rear tires enhance stability and pulling capability, making it ideal for tilling and heavy-duty applications. However, the narrower front tires may pose challenges in softer soils, potentially leading to reduced steering control under load.
