ENGINE DETAIL
The John Deere 7425 features a robust PE6068 6-cylinder diesel engine with a displacement of 6.8L, delivering 138 hp at a rated RPM of 2100, making it suitable for various agricultural tasks requiring consistent power output. Its 16.9:1 compression ratio indicates efficient fuel combustion, while the effective idle range (850-2250 RPM) provides flexibility for different operational needs; however, maintenance of proper valve clearances (0.014in for intake and 0.018in for exhaust) is critical to ensure optimal performance. With oil and coolant capacities of 20.6 quarts and 21.1 quarts, respectively, adequate lubrication and cooling are essential for the longevity of this equipment under heavy workload conditions.

JOHN DEERE 7425 TIRES
The John Deere 7425 tractor offers both 2WD and 4WD configurations, with standard agricultural tires that provide versatility for various terrains. The 2WD setup, featuring 10.00-16 front and 18.4-38 rear tires, is suitable for flat land cultivation, while the 4WD configuration, equipped with 14.9-28 front and 18.4 rear tires, enhances traction and stability in challenging conditions such as hills or wet soil. A potential challenge in 2WD is reduced maneuverability in uneven terrain, making the 4WD choice favorable for more demanding agricultural tasks.
