ENGINE DETAIL
The International Harvester 4586 features a powerful 13.1L turbocharged DV-800 engine, delivering 300hp at 2600 RPM and a peak torque of 725 lb-ft at 1800 RPM, ideal for heavy-duty tasks such as plowing and tilling. Its dual dry air cleaner with a dust unloader enhances engine longevity by minimizing particulate intake, while the 15.6:1 compression ratio improves efficiency but may present challenges in fuel choice. Optimal for large-scale agricultural operations, it's crucial to consider the maintenance requirements associated with an 8-cylinder engine, including valve clearance adjustments (0.014 inches intake, 0.016 inches exhaust) to maintain performance.

TRACTOR HITCH
INTERNATIONAL HARVESTER 4586 TIRES
The International Harvester 4586 tractor is equipped with large 24.5-32 Ag tires, providing excellent traction and stability, particularly in heavy tillage operations or on uneven terrain. However, the tractor's weight distribution might create challenges in softer soils, potentially leading to compaction. Ideal for large-scale farming, its robust design allows for effective handling of heavy implements while maintaining efficient power delivery.
