ENGINE DETAIL
The McCormick Intl GM55 tractor features a Yanmar 4TNV84T turbocharged diesel engine, providing a balance between power (54.2 hp) and a solid torque output (117.6 lb-ft) at a low RPM (1200), ideal for tasks requiring high pulling capacity. With a Tier III emissions rating, it meets environmental standards while the direct injection fuel system enhances efficiency and responsiveness. However, its relatively limited power may be a challenge for heavier agricultural tasks, making it well-suited for moderate land maintenance rather than intensive field operations.
