ENGINE DETAIL
The John Deere 7320 tractor features a robust 6.8L PowerTech diesel engine, delivering 125hp at 2300 RPM with a substantial torque of 375 lb-ft at 1500 RPM, making it efficient for heavy-duty agricultural tasks. A pros of the engine design is its high compression ratio of 16.9:1, enhancing fuel efficiency and power output, while the torque curve provides substantial pulling power in the mid-RPM range, ideal for plowing and tilling. However, be mindful of the oil and coolant capacities (22.2 quarts and 25.2 quarts, respectively); these specifications necessitate regular monitoring and maintenance to prevent overheating and ensure optimal engine performance.
