Part of the New Holland Operator Manuals.
Leaf trash packs the oil cooler ahead of the radiator by midseason, and the coolant gauge starts creeping on the headland turn. This book settles what no forum thread can: how the cooler pack should be cleaned, how much coolant goes back in, and which switch kills the battery before you open anything.
New Holland published it for the T4.80V, T4.90V, T4.100V and T4.110V narrow tractors, and its 402 pages run from the cab controls, throttle, clutch and brakes through PTO and three-point hitch work, remote hydraulics, the full maintenance schedule, fuse and relay identification, and transmission and lift calibration.
Most of this work happens with nobody in the yard to ask. The maintenance chart and identification plates give you what to service and the data to quote when you order filters and parts, so the right part arrives the first time and the tractor is back in the field on schedule.

New Holland T4.80V, T4.90V, T4.100V, T4.110V Common Problems This Manual Covers
Remote hydraulic flow falls off at the taps
On cab models with the 80 l/min pump and the optional mid-mount valves, a hydraulic motor running slow off the pressure taps often just has the flow control potentiometer turned down rather than a tired pump. It sets delivery from 0 to 45.0 L/min (9.9 UK gpm), and the Working Operations section shows the control before you start pulling lines.
Manual Section: Working Operations p. 153Wheel track bolts working loose
Setting track width for row spacing and then skipping the retorque lets the discs fret and the holes elongate. Working Operations gives the figures: 220 N·m (162.3 lb ft) on the front M16 hardware, 310 N·m (228.6 lb ft) on the rear M18, and 250.0 N·m (184.4 lb ft) where the disc bolts to the rim.
Manual Section: Working Operations p. 201Temperature climbing from a blinded cooler pack
Chaff and dust blind the oil cooler and radiator core in close row work, and blasting them too hard drives debris deeper or folds the fins. As Required Maintenance has you blow the radiator and intercooler out with compressed air, and limits the air jet to below 5.0 bar (72.5 psi) at a minimum of 30 cm when cleaning the secondary air filter.
Manual Section: As Required Maintenance p. 238Refilling by guess after a hydraulic service
Draining the system and topping off by eye is how lift response goes soft and the dipstick stops telling the truth. General Maintenance Information lists the hydraulic system at 44.00 L, engine oil at 9.50 L including the filter, and brake fluid at 0.50 L.
Manual Section: General Maintenance Information p. 223Intermittent electrical faults
Electrical faults that come and go are often loose or corroded battery terminals and connections, which the electrical troubleshooting chart lists first. Electrical System Maintenance maps fuse identification and relay locations along with battery access and the cut-off switch, so you can isolate the circuit before buying parts.
Manual Section: Electrical System Maintenance p. 327Hitch or shuttle misbehaves after repair work
Electronic lift and Dual Command transmission components can be left out of step until they are recalibrated, so the three-point hitch drifts or the shuttle engages roughly. The Maintenance chapter carries both calibration procedures, and chapter 8 Troubleshooting adds engine, electrical and hydraulic troubleshooting charts.
Manual Section: Maintenance / Troubleshooting p. 345Clutch drag and a handbrake that slips
A clutch that will not release cleanly, or a parking brake that creeps on a slope, is worth checking against the book before suspecting worn parts. As Required Maintenance gives the clutch pedal position, value A at 150 mm (5.91 in), and the parking brake adjustment.
Manual Section: As Required Maintenance p. 231Frequently Asked Questions
Which tractors does this operator manual cover?
The New Holland T4.80V, T4.90V, T4.100V and T4.110V, published under number 48132178. Coolant capacity is listed separately for cab and cabless builds, so match the figures to your own configuration before topping up.
Does it list refill capacities for a full service?
Yes. Fuel tank 96.00 L, hydraulic system 44.00 L, front axle housing 4.00 L with 0.60 L in each front final drive, and coolant at 16.00 L on cab models or 14.00 L without a cab. p. 223
What torque do the wheel nuts take on the New Holland T4.80V-T4.110V?
Disc to hub nuts tighten to 220 N·m (162.3 lb ft) at the front (M16) and 310 N·m (228.6 lb ft) at the rear (M18), with disc to rim nuts at 250.0 N·m (184.4 lb ft). Recheck them after the first stretch of work. p. 304
Will it help with a fault or a lift that misbehaves?
The Maintenance chapter covers Dual Command transmission and electronic lift calibration, and chapter 8 Troubleshooting has engine, electrical and hydraulic troubleshooting charts. It is an operator manual, so it guides diagnosis and adjustment rather than internal overhaul. p. 345
