General Characteristics:
High torque, robust construction for heavy-duty agricultural applications.
Type:
High-pressure common rail or rotary injection fuel systems, depending on specific engine configuration.
General Notes:
Dimensions vary by specific model (8670, 8770, 8870, 8970). These are large, high-horsepower tractors. Refer to specific model data for exact figures.
Operating Weight Range:
Typically ranges from 15,000 lbs to over 20,000 lbs (6,800 kg to 9,000+ kg) depending on configuration and ballast.
Engine Oil Change:
Typically every 250 hours of operation, or annually, whichever comes first. Specific interval depends on operating conditions and oil type.
Hydraulic Fluid Change:
Refer to manual for specific intervals, often tied to filter changes and system checks (e.g., every 1000-1500 hours).
Engine Oil Grade:
API CJ-4 or CI-4, SAE 15W-40 or 10W-30, depending on ambient temperature. Consult manual for exact specifications.
Hydraulic Fluid Type:
New Holland recommends specific ISO VG 46 hydraulic fluid or equivalent. Refer to manual for exact OEM specifications.
Transmission Performance:
Potential for transmission clutch pack wear or electronic control unit (ECU) issues with high operating hours. Regular diagnostic checks are advised.
Hydraulic System:
Wear in hydraulic pumps or valves can lead to reduced lift capacity or control issues. Maintaining fluid quality is critical.
Origin:
Founded in 1895 in Pennsylvania, New Holland has a long history in agricultural machinery, notably with innovations in baling technology.
Acquisition By Ford:
New Holland was acquired by Ford Tractor Operations in 1985, leading to the Ford New Holland branding.
Acquisition By Fiat:
In 1990, Ford sold a majority interest to FIAT, and the New Holland brand continued to be prominent. In 1999, merged with Case IH to form CNH Global.
Era:
The 70 Series tractors, including the 8670, 8770, 8870, and 8970, were produced during the period following Ford's acquisition and the eventual FIAT integration, representing a key generation of New Holland's high-horsepower offerings.
