ENGINES OVERVIEW
The Cockshutt 80 tractor features a choice between a Waukesha-Oliver 5.5L 4-cylinder kerosene engine or a 4.9L 4-cylinder gasoline engine, providing versatility in fuel options, which can enhance operational efficiency depending on availability and cost. The kerosene variant typically offers better torque for agricultural applications but may require additional starting procedures. Conversely, the gasoline engine is more straightforward for everyday use, making it suitable for lighter workloads or less experienced operators.

ENGINE DETAIL 1
The Cockshutt 80 features a 4-cylinder, kerosene-powered Waukesha-Oliver engine with a significant displacement of 334 ci (5.5 L), providing robust torque at low RPM (1200), which is ideal for heavy tillage and pulling applications. The oil bath air cleaner enhances filtration but may require more maintenance compared to modern paper filters. The hand-crank starter is less convenient and can pose challenges in colder climates or for inexperienced operators, making this tractor more suited for those familiar with traditional starting methods.

| Bore/Stroke | 4.50x5.25 inches/114 x 133 mm |
| Air cleaner | oil bath |
| Rated RPM | 1200 |
| Starter type | hand-crank |
ENGINE DETAIL 2
The Cockshutt 80 features a Waukesha-Oliver gasoline 4-cylinder engine with a substantial displacement of 298 ci (4.9 L), providing adequate torque for various agricultural tasks. With a bore and stroke of 4.25x5.25 inches (108 x 133 mm), its design allows for smooth power delivery, although the hand-crank starter may present challenges in ease of use compared to modern electric starting systems. This tractor, rated at 1200 RPM, is best suited for low-speed applications like plowing or tilling, benefiting from its reliable oil bath air cleaner under moderate dust conditions.

COCKSHUTT 80 ENGINES
The Cockshutt 80 tractor features a dual-fuel system, utilizing a Waukesha-Oliver engine available in both kerosene (5.5L) and gasoline (4.9L) variants, allowing for versatility in fuel choice depending on availability. Its fuel tank capacity varies between 13 gallons (early models) and 17 gallons (post-1938), granting extended operational range while impacting weight distribution. A potential challenge is the need for fuel type selection based on application, which may affect performance efficiency in differing agricultural tasks.

TRANSMISSIONS OVERVIEW
The Cockshutt 80 tractor features either a 3-speed or a 4-speed transmission, providing flexibility for various farming tasks; the 4-speed option enhances versatility for different operating conditions. The choice of gear ratios allows optimized power delivery and fuel efficiency, particularly in fieldwork and transport scenarios. However, operators must consider the potential complexity of shifting mechanisms when selecting between the two gear options, as this can affect ease of operation in varied terrains.
| Description | 3-speed gear/4-speed gear |
TRANSMISSION 1
The Cockshutt 80 features a simple 3 forward and 1 reverse gear configuration, making it suitable for basic agricultural tasks. Its dry disc clutch offers reliable engagement but may require more maintenance compared to wet clutches, particularly under heavy use. This tractor is ideal for small to medium-sized farms where straightforward gear operation and ease of repairs are prioritized.

| Gears | 3 forward and 1 reverse |
| Clutch | dry disc |
TRANSMISSION 2
The Cockshutt 80 features a 4-speed gear transmission, enhancing versatility in various field applications and improving operational efficiency. Its dry disc clutch provides reliable power transfer and is low maintenance, but may demand precise engagement to prevent slippage. Ideal for farmers requiring a robust machine for diverse tasks, it balances simplicity with functional performance.

| Description | The four-speed transmission was added to the Row-Crop 80 in 1939. |
MECHANICAL
The Cockshutt 80 tractor features a 4x2 2WD chassis which provides adequate traction for light to moderate fieldwork, but may struggle on steep or challenging terrain compared to 4WD models. The manual steering system enhances reliability but requires more physical effort, particularly in tight maneuvers. With a 3-speed gear option, it delivers suitable power for basic tasks, while the 4-speed gear allows for better speed management, improving versatility across varying field conditions.

COCKSHUTT 80 TIRES
The Cockshutt 80 tractor features Ag rear tires in sizes 11.25-40 or 11.25-42, offering good traction and stability for various field operations. The choice of tire size may affect load capacity and ground clearance; the 42-inch tires provide slightly better flotation in softer soils. However, tire wear and maintenance can be a challenge, especially in heavy-duty applications.
