ENGINES OVERVIEW
The Cockshutt 50 tractor features a Buda 4.5L 6-cylinder engine, available in both gasoline and diesel variants, offering flexibility in fuel choice which can enhance usability for different operational needs. The 4.5L displacement provides substantial power output for medium-duty tasks, while the diesel version typically offers improved fuel efficiency and torque for heavy-duty applications. However, considering maintenance and parts availability, it’s crucial to assess the long-term support for this vintage model before acquisition.

ENGINE DETAIL 1
The Cockshutt 50 features a robust 6-cylinder Buda gasoline engine with a displacement of 273 ci (4.5 L), delivering reliable performance at a rated RPM of 1650. With a bore and stroke of 3.75 x 4.125 inches (95 x 105 mm) and a compression ratio of 6.6:1, it strikes a balance between power and efficiency, making it suitable for moderate agricultural tasks. However, the relatively low compression ratio may limit power output compared to contemporary tractors, posing potential challenges in heavy-duty applications.

ENGINE DETAIL 2
The Cockshutt 50 tractor features a robust Buda diesel engine with a 6-cylinder, 273 ci displacement, delivering efficient power at a rated RPM of 1650. The high compression ratio of 14.3:1 enhances fuel efficiency while the vertical I-head design promotes optimal airflow for improved combustion. Consider suitability for heavy-duty applications where torque at low RPM is crucial, though the engine's complexity may pose challenges in maintenance.

COCKSHUTT 50 ENGINES
The Cockshutt 50 is equipped with a robust Buda 4.5L 6-cylinder engine, available in both gasoline and diesel variants, providing flexibility for differing fuel preferences. Its 21-gallon (79.5 L) fuel tank offers extended operational range, making it suitable for longer tasks without frequent refueling. However, the choice between gasoline and diesel may affect torque performance and fuel efficiency, with gasoline typically offering higher RPMs while diesel provides better torque at lower speeds for heavier tasks.

TRANSMISSION
The Cockshutt 50 features an unsynchronized gear system, which can present challenges in shifting, particularly under load. With 6 forward and 2 reverse gears, it offers a versatile range for various agricultural tasks, but operators must be skilled to avoid grinding during gear changes. The dry disc clutch provides reliability and durability, yet it may require more maintenance than hydraulic systems in applications with frequent use.

MECHANICAL
The Cockshutt 50 tractor features a 4x2 2WD chassis, providing basic traction ideal for flat terrains but limited in slippery conditions. Its independent mechanical disc brakes offer reliable stopping power, although they may require more maintenance than hydraulic systems. The open operator station enhances visibility and air circulation but exposes the operator to the elements, which may affect comfort during prolonged usage, particularly in adverse weather.

COCKSHUTT 50 TIRES
The Cockshutt 50 tractor features an Ag front tire size of 7.50x16 and a larger Ag rear tire size of 14.00x34, optimizing traction and stability for agricultural tasks. The rear tire's substantial diameter enhances ground engagement and weight distribution, effectively reducing soil compaction—a vital factor for crop health. However, the size difference may challenge maneuverability in tight spaces, making it best suited for open field operations.
