Horsepower Range:
Varies by model, typically 200-300+ PTO horsepower, with power boost capabilities.
Torque Range:
High torque output for pulling heavy loads, specific figures vary by model and engine tuning.
Injection System:
Common Rail Direct Injection (CRDI) with electronic control.
Emission Controls:
Likely Tier 3/4a compliant, incorporating exhaust gas recirculation (EGR) and potentially diesel particulate filters (DPF) or selective catalytic reduction (SCR) depending on exact model year.
Wheelbase:
Significant, designed for stability with heavy implements. Specific figures vary by axle configuration and model, generally over 115 inches (approx. 2921 mm).
Overall Length:
Varies, typically 190-220 inches (approx. 4826-5588 mm) excluding implements.
Overall Width:
Varies, depends on tire configuration, typically 70-100 inches (approx. 1778-2540 mm).
Operating Weight:
Substantial, typically 18,000 - 25,000 lbs (approx. 8,165 - 11,340 kg) unballasted, depending on configuration.
Max Gross Weight:
Significantly higher, allowing for substantial ballast and implement weight.
Engine Oil And Filter:
Typically 250-500 hours, depending on operating conditions and oil type. Refer to manual for exact interval.
Transmission Hydraulic Filter:
Often at 1000-1200 hours or as indicated by hydraulic system monitoring.
Fuel Filters:
At specified intervals, often coinciding with oil changes or based on fuel quality.
Engine Oil:
API CJ-4 or newer (CK-4) heavy-duty diesel engine oil, SAE 15W-40 or 10W-30 (check manual for ambient temperature suitability).
Coolant:
Ethylene glycol-based antifreeze, typically with a 50/50 mix with deionized water, meeting specific CNH specifications.
Hydraulic Fluid:
CNH specification MAT 3525 or MAT 3540 (Ultra-Low Viscosity Tractor Hydraulic Fluid) is often recommended for optimal performance in powershift and CVT transmissions and hydraulic systems.
Common Concerns:
While generally robust, typical concerns for tractors of this era/class can include wear on transmission clutch packs, hydraulic pump or valve issues under extreme use, and electrical component failures (sensors, control modules) due to vibration and environmental exposure. Proper maintenance is key.
