Part of the New Holland Operator Manuals.
Engine, transmission, hydraulics, three point hitch, brakes: this operator manual walks the New Holland T4.65 and T4.75 through every system a farm puts to work in a season, from starting the F5D engine to engaging four wheel drive and the differential lock for a wet headland. It applies to tractors from serial number ZDAH00008 and above, runs 304 pages in English, publication 47955162.
Guessing at a torque or a fluid quantity is how studs shear and seals weep mid harvest. The Maintenance section pins the real numbers down, 8.5 L in the engine sump, 90 L in the fuel tank, 36 L in the transmission, alongside the full service chart, so the figure you work to came from the factory and not from a forum thread.
As a PDF it lives on the phone or laptop already riding in the cab, so the answer is wherever the tractor is, not back at the house.

New Holland T4.65, T4.75 Common Problems This Manual Covers
Engine fault codes with no explanation
A code on the instrument panel means nothing without the resolution table. The Troubleshooting section covers fault code resolution for the engine, electrical system, and hydraulics so you can tell a sensor fault from a real failure before calling the dealer.
Manual Section: Troubleshooting p. 257Hard starting from fuel contamination
Farm-stored diesel carries water and sediment that clog the filter and leave the tractor cranking without firing. The Maintenance section lays out the fuel filter service intervals and procedure, including how far to tighten the new filter by hand.
Manual Section: Maintenance p. 173Four wheel drive will not engage
Front axle drive that stays out when a loaded trailer needs it is a common complaint on these tractors. The Working Operations section covers both mechanical engagement and the electro-hydraulic control, so you can check the operating procedure before assuming a failure.
Manual Section: Working Operations p. 119Three point hitch lifts slowly
An implement that creeps up or will not lift at all usually traces to the rear hydraulics. The Troubleshooting section includes a dedicated rear three point hitch table plus coverage of the remote couplers, narrowing the cause before anything comes apart.
Manual Section: Troubleshooting p. 257Light rear end under loader work
A cab loader with a full bucket unloads the rear axle and the tractor loses traction and steering feel. The Accessories section covers the single piece ballast option so the machine can be weighted correctly instead of worked dangerously light.
Manual Section: Accessories p. 289Unknown warning lights on the panel
The T4 instrument panel carries symbols that are easy to misread, and ignoring the wrong one costs an engine. The Controls and Instruments section identifies the instrument panel, front controls, and console switches item by item.
Manual Section: Controls and Instruments p. 59Towing a dead tractor safely
Dragging a disabled tractor out of the field the wrong way can damage the transmission. The Transport Operations section covers recovery towing and road transport so the trip to the shop does not create a second repair.
Manual Section: Transport Operations p. 117Frequently Asked Questions
