Part of the New Holland Operator Manuals.
This 256-page New Holland T4020 operator manual PDF (OEM ID 47394627) covers four tractors in the range, T4020 through T4050. Service intervals run from the 10-hour checks to the 1800-hour items, set out in a lubrication table with the instrument panel warning lights decoded in the same chapter. Field chapters cover the three-point linkage, independent and synchronized PTO, differential lock, rear remotes, ballast and maximum permitted weights, while the troubleshooting chart sorts faults by engine, electrical, hydraulic lift and brakes. Hold the air line under 5 bar when you blow out the filter element, and give the fuel filter three quarters of a turn (15 Nm). Bookmarked and text-searchable, the file travels in your cab on a phone or tablet.
