ENGINE DETAIL 1
The Cockshutt 1555 features a robust Waukesha-Oliver 6-cylinder diesel engine with a relatively high compression ratio of 16.5:1, optimizing power output and fuel efficiency. With a displacement of 232 ci (3.8L) and a rated RPM of 2200, it is well-suited for moderate to heavy-duty applications, although operators should ensure adequate cooling given its coolant capacity of 20 qts (18.9L). Additionally, the dry air cleaner may pose challenges in dusty environments, as it requires regular maintenance to prevent performance degradation.

ENGINE DETAIL 2
The Cockshutt 1555 features a robust Waukesha-Oliver 6-cylinder gasoline engine with a displacement of 232ci, providing adequate power for mid-range agricultural tasks. Its 8:1 compression ratio and 2200 RPM rated speed optimize fuel efficiency while ensuring reliable performance; however, the dry air cleaner may necessitate more maintenance under dusty conditions. With oil and coolant capacities of 6 quarts and 20 quarts respectively, routine servicing is crucial for prolonged engine life and effective thermal management in heavy-duty scenarios.

TRANSMISSIONS OVERVIEW
The Cockshutt 1555 features a 12-speed partial power shift transmission, enhancing versatility and efficiency in varying field conditions by allowing smoother transitions between gears without a full clutch engagement. However, the 6-speed unsynchronized gear may pose challenges in operation at higher speeds or during rapid shifting, potentially leading to increased wear on the transmission components. This tractor is particularly advantageous for tasks requiring frequent speed adjustments, such as plowing or planting, where maintaining engine power is crucial.

TRANSMISSION 1
The Cockshutt 1555 features a Hydra-Power partial power shift transmission, allowing operators to effectively manage a 12 forward and 4 reverse gear setup, optimizing performance across varying field conditions. The 279.4mm dry disc clutch enhances durability but may require careful maintenance to prevent slippage during heavy loads. This transmission configuration is advantageous for tasks that require quick gear changes, although operators may need to adapt their driving style to fully leverage its capabilities.

| Description | The Hydra-Power transmission provides a two-speed power shift between direct-drive and the lower Hydra-Power range |
TRANSMISSION 2
The Cockshutt 1555 features an unsynchronized gear transmission with 6 forward and 2 reverse gears, which may require skillful shifting to ensure smooth operation. The 279.4mm dry disc clutch provides sufficient torque transfer but may present challenges during engagement under load. Its 40-quart (37.9L) oil capacity facilitates extended operational periods, though regular maintenance is necessary to prevent potential overheating and ensure optimal performance.

MECHANICAL
The Cockshutt 1555 features a 4x2 2WD chassis, which is ideal for flat terrain and lighter agricultural tasks but may struggle in challenging field conditions with traction issues. The power steering enhances maneuverability, while the disc brakes provide reliable stopping power, although an open operator station may expose the operator to the elements without the optional cab with heater. The 12-speed partial power shift transmission allows for efficient speed adjustments, benefiting tasks such as plowing or tilling, but the 6-speed unsynchronized gear limits high-speed road transport efficiency.
