ENGINES OVERVIEW
The CO-OP E5 tractor features a Buda 4.5L engine available in both gasoline and diesel variants, offering versatility for various agricultural applications. The gasoline engine provides smoother operation and quicker starts, making it suitable for lighter tasks, whereas the diesel version boasts superior fuel efficiency and torque for heavy-duty work. However, operational costs may vary, with diesel generally offering lower fuel costs but higher maintenance due to the complexity of diesel systems.

ENGINE DETAIL 1
The CO-OP E5 tractor features a Buda gasoline 6-cylinder engine with a substantial displacement of 273 cubic inches (4.5 L), which provides a good balance of power for agricultural tasks. With a bore/stroke ratio of 3.75x4.125 inches and a low compression ratio of 6.6:1, it is optimized for torque at lower RPMs, making it suitable for plowing and heavy lifting activities. However, the lower RPM rating of 1650 may limit its efficiency for high-speed operations, indicating that it's best employed in scenarios requiring steady power output rather than quick acceleration.

ENGINE DETAIL 2
The CO-OP E5 tractor features a robust Buda 6-cylinder diesel engine with a displacement of 4.5L, providing ample torque for demanding applications, particularly in agricultural tasks. With a compression ratio of 14.3:1 and a rated RPM of 1650, it delivers efficient fuel combustion and operational efficiency at lower speeds, which is advantageous for power-intensive tasks such as plowing or tilling. However, the relatively high compression may necessitate premium fuel and could lead to increased wear if not properly maintained.

CO-OP E5 ENGINES
The CO-OP E5 tractor is equipped with a robust Buda 4.5L 6-cylinder engine available in both gasoline and diesel variants, providing flexibility depending on fuel availability and user preference. Its substantial 21-gallon (79.5L) fuel tank offers extended operational time, making it suitable for large-scale agricultural tasks without frequent refueling. However, potential users should consider the trade-off between gasoline's higher RPM efficiency and diesel's torque advantages, particularly in heavy lifting or plowing scenarios.

TRANSMISSION
The CO-OP E5 tractor features a 6F/2R unsynchronized gear transmission, which may complicate gear shifting under load, requiring precise timing from the operator for smoother transitions. The dry disc clutch offers a straightforward design, but it may lead to quicker wear under frequent engagement and disengagement in demanding conditions. This combination is suitable for basic agricultural tasks, but operators should be mindful of potential challenges when navigating varied terrain or operating heavy implements.
| Type | unsynchronized gear |
| Gears | 6 forward and 2 reverse |
| Clutch | dry disc |
MECHANICAL
The CO-OP E5 tractor features a 4x2 2WD chassis, which provides adequate traction for light agricultural tasks but may struggle on uneven terrain or wet conditions. Its independent mechanical disc brakes ensure reliable stopping power, though they might require more maintenance compared to hydraulic systems. The open operator station enhances visibility and accessibility, but exposes the operator to environmental conditions; therefore, this tractor is ideally suited for short-duration operations in well-maintained fields.

CO-OP E5 TIRES
The CO-OP E5 tractor features Ag front tires sized 7.50x16 and Ag rear tires sized 14.00x34, providing a stable and balanced stance ideal for agricultural applications. The larger rear tires enhance traction and load-bearing capacity, making it suitable for heavier field tasks, while the front tires allow for maneuverability in tight spaces. However, operators should be mindful of tire wear rates on diverse terrains, as uneven soil conditions may challenge stability and handling.

DIMENSIONS & TIRES
The CO-OP E5 tractor features a wheelbase of 86.5 inches, providing stability and maneuverability for various agricultural applications. Weighing between 6041 to 6163 pounds allows it to handle heavier implements while maintaining a lower ground pressure, which is advantageous in softer soil conditions. However, the front and rear tire sizes (7.50x16 and 14.00x34, respectively) may limit traction on uneven terrain, necessitating consideration of the field conditions for optimal performance.
