ENGINE DETAIL
The CO-OP 2 tractor features a Chrysler 6-cylinder gasoline engine with a displacement of 3.3 liters, providing adequate torque for agricultural tasks while maintaining lower operating RPM at 1500, which can enhance engine longevity. The liquid-cooled system with an 18-quart coolant capacity ensures effective heat management, potentially preventing overheating during prolonged use. However, the engine's displacement and design suggest limited fuel efficiency compared to modern diesel alternatives, impacting long-term operational costs in high-use scenarios.

CO-OP 2 ENGINE
The CO-OP 2 tractor is equipped with a Chrysler 3.3L 6-cylinder gasoline engine, providing robust power suitable for various agricultural tasks. With a 22-gallon fuel tank, it offers extended operational time between refuels, making it advantageous for larger fields or prolonged projects. However, gasoline engines may face inefficiencies in fuel consumption compared to diesel alternatives, particularly in heavy-duty applications.

TRANSMISSION
The CO-OP 2 tractor features a 5-forward, 1-reverse unsynchronized gear system, which may lead to challenges during gear shifting under load, potentially increasing wear on components. This type of transmission is generally less efficient for heavy-duty operations compared to synchronized systems but can offer simpler mechanics and reduced repair costs. Ideal for lighter agricultural tasks, operators should be prepared for manual coordination when changing gears to achieve optimal performance.
| Type | unsynchronized gear |
| Gears | 5 forward and 1 reverse |
MECHANICAL
The CO-OP 2 tractor's 4x2 2WD chassis is suitable for light-duty applications, providing good maneuverability but limited traction in adverse conditions. An open operator station enhances visibility and operator comfort, yet exposes the operator to environmental elements. The 5-speed unsynchronized transmission facilitates simple operation but may pose challenges in gear shifting, particularly for inexperienced operators.

CO-OP 2 TIRES
The CO-OP 2 tractor features agricultural front tires sized 6.00-16 and rear tires sized 11.25-28, offering a balance between traction and stability in various field conditions. The narrower front tire design aids in maneuverability within confined spaces, while the larger rear tires enhance load-carrying capacity and power transfer to the ground. However, users should consider potential challenges with flotation in soft soils, as tire sizing may necessitate wider options for optimal performance in muddy or loose conditions.

DIMENSIONS & TIRES
The CO-OP 2 tractor weighs 5,000 lbs (2,268 kg), providing a stable base for various agricultural tasks, particularly suited for light to medium-duty operations. The front tires (6.00-16) and rear tires (11.25-28) offer a good balance of traction and flotation, making it effective for field work on looser soils. However, its weight may limit mobility on rough terrains and require careful load management to prevent excessive soil compaction.
