Part of the New Holland Operator Manuals.
Wiring routing, PTO speeds, and service intervals for New Holland's T4 V series live in one place: the 466 page New Holland T4.80V to T4.110V series operator manual PDF, OEM number 51601841, the factory book for all four narrow tractor variants. Fuse and relay locations map the cab electrics, and the wiring diagrams near the back let you trace a dead work lamp or a no-start back to the circuit. Troubleshooting charts close the book, sorting engine, electrical, and hydraulic complaints by symptom, while working operations, the longest run in the book, covers rear remote valves, differential lock, draft on the rear three-point hitch, and liquid ballast. At 600 hours you check wheel nut torque, 220 N·m (162.3 lb ft) on the M16 front bolts and 310 N·m (228.6 lb ft) on the M18 rear ones, and every rear remote takes 1/2 inch push-pull couplers. Hay waits on nobody while you hunt one figure. Bookmarked and searchable, it prints clean enough to live on the bench and get greasy.

New Holland T4.80V, T4.90V, T4.100V, T4.110V Common Problems This Manual Covers
New Holland T4.80V will not crank or drops into neutral unexpectedly when the shuttle lever is moved
Check the fuse and relay layout on page 391 before chasing wiring. Verify F-031 (40 A starter switch) and F-014 (10 A Power Shuttle) are intact, then clean the battery ground strap. Measure battery voltage at rest: 12.66 V is full charge, 12.00 V is only 25 percent and will crank slowly.
Manual Section: Electrical System TroubleshootingThree-point hitch lifts slowly or will not raise the implement at full throttle
Check hydraulic oil level first, before blaming the pump. The rear axle, transmission, and hydraulic lift share one 44.0 L charge of AMBRA MULTI G oil, listed on page 362, so a small leak drops lift speed fast. Top up to the sight glass mark, then cycle the lift several times to purge air.
Manual Section: Rear Three-Point Hitch TroubleshootingRemote hydraulic coupler will not connect to the implement hose or weeps oil at the fitting
Wipe the coupler face clean and relieve trapped pressure in the implement hose before connecting. Each auxiliary valve uses two 1/2 inch quick-connect female push-pull couplers, described on page 193, so check that the male tip on the implement matches. Replace any coupler with a nicked or grooved sealing face.
Manual Section: Couplers TroubleshootingDashboard gauges go dead or the charge light flickers while working
Check the battery terminals and ground strap at the battery access point covered on page 381, since loose grounds kill gauges first. Measure open-circuit battery voltage: 12.45 V means 75 percent charge, 12.30 V means half. Clean both posts, retighten, and inspect the cluster connector for green corrosion.
Manual Section: Electrical System TroubleshootingCab blows dusty air, windows fog up, or air conditioning stops cooling
Clean or replace the cab recirculation and fresh-air filters on the schedule given in the maintenance chart on page 282. Verify the cab door and window seals close tight, since a poor seal pulls field dust straight into the cab. Check the condenser and radiator screen for chaff and blow it out from the fan side.
Manual Section: Cab Climate Control TroubleshootingEngine runs hot, loses power, or smokes under load during long field passes
Clean the radiator, intercooler, and oil cooler screens of chaff before every long day, following the engine cooling maintenance on page 285. Verify engine oil level on the dipstick: the engine holds 9.50 L (2.09 UK gal) with the filter, 6.4 to 8.1 L in the sump alone, listed on page 279. Check the fuel filters for water if power drops off gradually.
Manual Section: Troubleshooting Engine p. 405Frequently Asked Questions
How do I reset the error codes on my New Holland T4.80V?
To view and manage error codes, enter the programming menu by pressing the switch (2) on the symbol (D) for more than three seconds. Navigate to the error codes screen (S1) using the switch (1) on the symbol (B), then press the switch (2) on the symbol (D) to view the codes in memory. Resetting saved, blocked, and current errors must be performed by an authorized dealer. p. 137
What are the front and rear wheel nut torque specs on a New Holland T4.80V, T4.90V, T4.100V, T4.110V?
The tightening torque for the front wheel nuts (M16) is 220 N·m (162.3 lb ft), and for the rear wheel nuts (M18) is 310 N·m (228.6 lb ft). p. 340
What is the engine oil capacity for the T4.80V model with a cab?
The engine oil capacity for models with a cab is 9.50 L (2.09 UK gal) when the filter is included, or 6.4 – 8.1 L (1.4 – 1.8 UK gal) for the oil sump only. p. 279
How often should I check the hoses, connections, and gaskets on my tractor?
You should check all hoses, connections, and gaskets to ensure integrity and cleanliness every 3 months or 150 hours of operation, whichever comes first. p. 273
What is the correct procedure for bleeding the fuel system after replacing the fuel filters?
After replacing the filters, tighten the bleed screw (1), then manually push the priming pump (2) until fuel starts to come out of the bleed screw (1) without air bubbles. Finally, tighten the bleed screw (1). p. 347
