ENGINE DETAIL
The Massey Ferguson 4900 is powered by a robust Cummins VT-903 turbocharged diesel engine, delivering high torque and efficiency, ideal for heavy-duty agricultural tasks. With a displacement of 14.8L and a compression ratio of 15.5:1, it offers significant power at a rated RPM of 2600, making it suitable for both field work and transport duties. Advantages include extended oil and coolant capacities (37.5qts and 60qts, respectively), which contribute to prolonged service intervals and reduced maintenance frequency, though the large displacement may pose challenges in emissions compliance depending on local regulations.

MASSEY FERGUSON 4900 TIRES
The Massey Ferguson 4900 tractor features a robust tire configuration with Ag front tires sized 18.4-38, optimizing traction and stability in various agricultural terrains. The rear tire options (18.4-38, 20.8-38, 24.5-32, 30.5-32) allow for customization based on load requirements and field conditions, enhancing performance while potentially complicating tire maintenance decisions. Users should consider the balance between tire size for maximum flotation and necessary ground penetration, especially in muddy or soft soil scenarios, to prevent compaction and improve crop yields.
