ENGINES OVERVIEW
The Cockshutt 1855 tractor is equipped with either an Oliver-Waukesha 5.1L 6-cylinder diesel or gasoline engine, offering flexibility in fuel choice to match operator preference and availability. The diesel variant provides superior torque and fuel efficiency, making it advantageous for heavy-duty applications such as plowing or towing, while the gasoline version may offer lower initial costs and easier starting in cold conditions. However, the diesel engine typically requires more maintenance due to its higher operating pressures, and operators should consider application requirements when selecting the engine type.

ENGINE DETAIL 1
The Cockshutt 1855 tractor is powered by a turbocharged Oliver-Waukesha 6-cylinder diesel engine, offering robust performance with a displacement of 5.1L and a compression ratio of 16:1, ideal for heavy-duty agricultural tasks. Its notable bore and stroke dimensions (98x111 mm) provide a balance of torque and efficiency at a rated RPM of 2400, although higher RPMs can lead to increased wear if not properly managed. The dry air cleaner system simplifies maintenance but may require more frequent checks in dusty environments, while a coolant capacity of 20 quarts ensures efficient temperature regulation during prolonged operation.

TRANSMISSIONS OVERVIEW
The Cockshutt 1855 features a 6-speed gear transmission combined with an 18-speed partial power shift system, providing versatile speed selection for various agricultural applications. This dual transmission configuration enhances operational efficiency, allowing for smoother transitions between gears, particularly beneficial in variable field conditions. However, the complexity of this transmission may pose a challenge in terms of maintenance and operator training.

TRANSMISSION 1
The Cockshutt 1855 tractor utilizes a 6-speed forward and 2-speed reverse gear system, providing versatility in various field conditions. The 330mm cerametallic disc clutch offers superior friction performance, allowing for smooth engagement while reducing slippage. While this combination enhances power transfer and operational efficiency, it may require careful operation to avoid overheating during prolonged use.

TRANSMISSION 2
The Cockshutt 1855 tractor features a Hydraul-Shift transmission with 18 forward and 6 reverse gears, allowing for versatile speed management in various field and transport applications. The partial power shift capability enhances performance by providing seamless gear changes without clutch interruption, improving operator efficiency. However, the reliance on a cerametallic disc clutch may present durability challenges under heavy use, necessitating careful maintenance practices to prolong lifespan.

MECHANICAL
The Cockshutt 1855 features a robust 4x2 or optional 4WD system, enhancing traction and stability, particularly beneficial in varied terrain. Its power steering system allows for easier maneuverability, while the hydraulic disc brakes provide reliable stopping power; however, the open operator station may expose the operator to the elements without the optional cab. The 6-speed gear transmission facilitates straightforward operation, but the 18-speed partial power shift can optimize performance in different field conditions, allowing for better adaptation to changing loads.
