ENGINE DETAIL
The Case 2670 tractor features a robust 8.3L turbocharged intercooled diesel engine with a high displacement, delivering 256hp at 2200 RPM, ideal for heavy-duty agricultural tasks. Its dual paper element air cleaner and 15.8:1 compression ratio enhance air intake efficiency and engine performance, but may require more frequent maintenance in dusty environments. With a substantial coolant capacity of 48 quarts, it provides effective thermal management, crucial for sustained operation under load, although attention should be given to ensure optimal cooling system maintenance to prevent overheating.

| Description | Four gears, each with a three-range power shift (high, intermediate, low) |
MECHANICAL
The Case 2670 tractor features a 4x4 4WD chassis, enhancing traction and stability on varied terrain, ideal for heavy-duty agricultural tasks. Its hydrostatic power steering with four-wheel steering allows for superior maneuverability in tight spaces, benefiting field operations and reducing operator fatigue. The hydraulic wet disc brakes offer reliable stopping power, while the 12-speed partial power shift transmission provides flexibility in power management, though operators may need to master its complexity for optimal performance.

J.I. CASE 2670 TIRES
The Case 2670 tractor is equipped with front and rear tire options of 18.4-30, providing good flotation and traction in various agricultural applications. The rear tire alternatives (20.8-34 and 23.1-30) allow for increased load capacity and improved ground clearance, making it suitable for heavier implements and rough terrain. However, the wider rear tire options may present challenges in tight spaces or on compacted soil, potentially leading to soil compaction or crop damage if not managed properly.
