ENGINE DETAIL
The J.I. Case 4494 features a robust turbocharged 6-cylinder diesel engine with a substantial displacement of 8.3L, delivering 213 hp at 2200 RPM and peak torque of 560 lb-ft at 1650 RPM, ideal for heavy-duty applications. With a compression ratio of 15.8:1, it ensures efficient fuel combustion but may require high-quality diesel to prevent knocking. Its significant oil and coolant capacities (24 qts and 48 qts, respectively) allow for extended operation, making the tractor suitable for prolonged fieldwork scenarios, although routine maintenance must be emphasized to ensure optimal engine longevity.
