JINMA JM-284 POWER
ENGINE DETAIL
The Jinma JM-284 is a compact 28 hp tractor featuring a robust 3-cylinder, liquid-cooled diesel engine with a high compression ratio of 22:1, which enhances fuel efficiency and torque output at its rated RPM of 2300. With a relatively small displacement of 1.5 L, it is suitable for tasks requiring maneuverability and lower operational costs; however, its power may limit performance in heavy-duty applications. Regular maintenance, including oil changes every 250 hours, is critical for reliability, and its oil and coolant capacities indicate a need for meticulous servicing to prevent overheating and mechanical failures.

TRANSMISSION
The Jinma JM-284 tractor is equipped with a 12 forward and 4 reverse gear system, featuring a low/high range and a creeper range that effectively doubles the available speeds. This versatility allows operators to efficiently handle various field applications, from slow, precise movements in tight spaces to faster transit speeds. However, the complexity of managing multiple gear settings may pose a learning curve for inexperienced operators.

MECHANICAL
The Jinma JM-284 tractor features a 4x4 MFWD design, enhancing traction and stability in various terrain, making it ideal for agricultural tasks on uneven ground. Its 12-speed gear transmission allows for versatile speed management, although the mechanical complexity may pose maintenance challenges. The two-post ROPS cab provides essential operator safety but offers limited protection from environmental elements compared to fully enclosed designs.
