ENGINE DETAIL
The Ferguson TO-20 is equipped with a Continental Z-120 engine, optimized for applications requiring moderate power and torque, with a 6.1:1 compression ratio that fosters efficient combustion at its rated 2200 RPM. The Marvel Schebler TSX updraft carburetor and oil bath air cleaner enhance air-fuel mixture quality and engine longevity, providing reliable performance but necessitating regular maintenance to avoid clogging. Its 88 lb-ft torque at 1200 RPM makes it suitable for tasks in agricultural environments where lower RPM operations, like plowing, are common, though limited power output may challenge heavier implement usage.

ENGINE OIL
The Ferguson TO-20 has an oil capacity of 6 quarts (5.7 liters), which is moderate for a tractor of its size, allowing for good lubrication and heat dissipation in the engine. Ensure regular oil changes to maintain optimal engine performance and prevent wear. A downside to consider is that during heavy use, frequent top-ups may be necessary, especially if there are oil leaks or consumption issues.
FERGUSON TO-20 ENGINE
The Ferguson TO-20, powered by a Continental 2.0L 4-cylinder gasoline engine, offers a balanced power-to-weight ratio suitable for light to moderate agricultural tasks. With a fuel tank capacity of 10 gallons (37.9 liters), it supports extended operational periods before refueling, making it efficient for larger plots. However, the vintage design may present challenges in parts availability and modern compatibility enhancements.

TRANSMISSION
The Ferguson TO-20 features a constant mesh transmission with helical-cut gears, ensuring smoother operation and reduced noise levels compared to straight-cut gears. It offers 4 forward and 1 reverse gear, suitable for a variety of tasks from farming to light industrial applications, though the limited number of gears may challenge its adaptability in more demanding scenarios. With an oil capacity of 18 quarts (17.0L), regular maintenance is crucial for optimal performance and longevity, necessitating periodic checks to prevent potential overheating or gear wear.

MECHANICAL
The Ferguson TO-20 features a 4x2 2WD chassis which limits traction on uneven terrain, making it ideal for flat, dry fields. Its manual steering provides direct feedback but may require more effort during extended use, especially in tight maneuvers. The differential mechanical brakes (11x2 inch) offer decent stopping power, although they may require more maintenance and attention compared to modern hydraulic systems, especially under heavy loads.

FERGUSON TO-20 TIRES
The Ferguson TO-20 tractor features 6.00-16-inch Ag front tires, enhancing maneuverability for tight spaces, while the 11-28-inch Ag rear tires provide improved traction for heavier loads on uneven terrain. This tire combination supports optimal weight distribution, making it suitable for various agricultural applications. However, its older design may limit compatibility with modern implements, necessitating careful selection to avoid potential performance challenges.

DIMENSIONS & TIRES
The Ferguson TO-20's 70-inch wheelbase provides enhanced maneuverability in tight spaces, making it suitable for small to medium-scale farming applications or landscaping. Weighing 2,760 lbs, it offers good stability and traction; however, its relatively narrow tire specifications (4.00-19 front and 10-28 rear) may limit performance in soft or muddy terrains. This tractor’s design is effective for light-duty tasks but may struggle with heavy-load operations compared to more robust models.
