History and service record of T4.90 to Workmaster 75

F34 and F36 engines. New Holland's T4 F/N/V brochure says the range uses F34 and F36 four-cylinder FPT Industrial engines with Stage V electronic fuel injection, from 75 to 120 horsepower, and that on the T4.90 and above Stage V is met with FPT's compact HI-eSCR 2 aftertreatment. T4 F/N/V Stage V brochure, New Holland.
Constant maximum power. New Holland says all T4 F/N/V models deliver constant maximum power between 1,900 and 2,300 rpm, with a common-rail injection system that raises power density and fuel efficiency. T4 F/N/V tractors brochure, New Holland.
EZ-Pilot Pro guidance. The brochure describes the EZ-Pilot Pro steering system as combining the EZ-Pilot engine and the NAV-900 guidance controller, which includes a receiver and terrain compensation in one device. T4 F/N/V Stage V brochure, New Holland.
Tier 4B strategy. New Holland's T4 Tier 4B brochure says tractors from 75 to 120 horsepower use the ECOBlue Compact HI-eSCR system with light cooled EGR, and that FPT Industrial has eliminated diesel particulate filters from all its Tier 4B engines above 75 hp. T4 Tier 4B tractors brochure, New Holland.
Stage V T4 F/N/V. A later brochure says the T4 F/N/V range meets Stage V, using FPT F34 and F36 four-cylinder engines of 75 to 120 hp, with compact HI-eSCR 2 on the T4.90 and above. T4 F/N/V Stage V brochure, New Holland.
Constant power band. New Holland says maximum power on these engines is delivered continuously from 1,900 to 2,300 rpm, which it ties to better fuel economy. T4 F/N/V tractors brochure, New Holland.
EZ-Pilot PRO guidance. The brochure lists the EZ-Pilot PRO system built on the EZ-Pilot steering engine and the NAV-900 guidance controller, which combines receiver and terrain compensation in one device. T4 F/N/V Stage V brochure, New Holland.
