ENGINE DETAIL
The CO-OP B1 tractor features a Hercules IXA3 gasoline engine with moderate displacement and a relatively low compression ratio of 5.75:1, which may enhance durability but limit power output, especially under load. Its manual start may challenge ease of use in lower temperature conditions, and the oil bath air cleaner provides effective filtration, although it may require more maintenance than dry options. The 1400 RPM drawbar rating suggests suitability for tasks like plowing or tilling, but operators may need to consider performance trade-offs at higher belt speeds.

CO-OP B1 ENGINE
The CO-OP B1 tractor features a Hercules 1.9L 4-cylinder gasoline engine that provides a balance of power and efficiency, suitable for light to moderate agricultural tasks. With a 12-gallon (45.4 L) fuel tank, it offers extended operational time between refueling, which can enhance productivity on larger fields. However, the gasoline engine may present higher operating costs compared to diesel counterparts, particularly in high-usage scenarios.

TRANSMISSION
The CO-OP B1 tractor features a straightforward [-|-] gear transmission with 3 forward and 1 reverse gear, providing basic operational flexibility for farming tasks. Its 9-inch dry plate clutch offers reliable engagement but may require more frequent maintenance compared to hydraulic systems, especially under heavy load scenarios. With an oil capacity of 10 quarts (9.5 L), ensuring proper lubrication is vital for optimal performance and longevity; users should monitor oil levels regularly to prevent potential engine wear.

SPEEDS
MECHANICAL
The CO-OP B1 tractor features a 4x2 2WD chassis, offering simplicity and lower cost but limiting traction on uneven terrain. Its open operator station enhances visibility and ventilation, though it exposes the operator to environmental elements. The 3-speed gear transmission allows for basic speed control, beneficial for lighter tasks but may hinder efficiency in more demanding operations requiring variable speed ranges.

POWER TAKE-OFF (PTO)
CO-OP B1 TIRES
The CO-OP B1 tractor is equipped with a 5.50-16 front tire and a 9-24 rear tire, providing a balanced combination for stability and traction in various agricultural applications. The larger rear tires offer improved soil grip and weight distribution, advantageous for plowing and fieldwork. However, the 5.50 front tires may limit maneuverability in tighter spaces, necessitating careful operation in confined areas.
