Part of the New Holland Operator Manuals.
Rear wheel nuts on a T4S work loose after the first hard week of loader duty, and the torque figures that keep them tight sit in the Maintenance section of this book. It carries New Holland publication number 51519607, runs 234 pages in English, and was written by the factory for the T4.55S, T4.65S and T4.75S tractors.
Coverage runs through Controls and Instruments, Operating Instructions, Transport Operations, and Working Operations, which handles front and rear wheel track settings, tire load ratings, remote hydraulics and the rear three-point hitch. Maintenance holds the full service chart and fluid capacities, Troubleshooting carries the fault-finding tables, and Specifications lists engine, cooling and electrical data.
A guessed torque or relief pressure is how a hub or a pump gets ruined in the middle of a season. Buy the PDF once, print the pages you need for the bench, and keep the file as long as the tractor is yours.

New Holland T4.55S, T4.65S, T4.75S Common Problems This Manual Covers
Wheel bolts loosen under loader work
Front loader work and rear ballast keep working at the hub bolts, and a loose wheel wallows out the studs quickly. The Maintenance section gives 245 N·m for dual-drive front wheel hub bolts and 280 N·m for the rear wheel hub bolts, so you retorque to a number instead of a guess.
Manual Section: Maintenance p. 128Water in the fuel filter sediment bowl
Condensation and dirty farm fuel settle in the sediment bowl, and the first sign is a tractor that stumbles under load halfway down a row. The maintenance chart calls for cleaning the sediment bowl every 50 hours and replacing the fuel filters every 300 hours.
Manual Section: Maintenance p. 122Three-point hitch lifts slowly
A hitch that struggles with a loaded implement usually points at system pressure or a tired pump rather than the linkage itself. The Specifications section gives the main safety valve setting of 190 bar, which is the reference figure to test against before anyone starts turning adjusters.
Manual Section: Specifications p. 181Clattering top end, hard cold starts
Valve clearances drift as the hours build, and a noisy top end with reluctant cold starting often traces straight back to them. Clearance checked cold is 0.30 ± 0.05 mm, listed in the Maintenance section along with the interval for checking it.
Manual Section: Maintenance p. 149Slow cranking on cold mornings
Short runs, PTO work and a marginal charge leave the battery flat on the one morning the ground is finally fit. The Specifications section gives the figures to test the charging and starting circuit against: 80 A alternator output, 100 A·h battery capacity and a 3.5 kW starter motor.
Manual Section: Specifications p. 183Remote couplers weeping oil
Quick couplers on the rear remotes take a beating from implement changes and start dripping oil down toward the drawbar. The Working Operations section covers the quick-connection hydraulic valves, including the 1/2 in bushing connector size, so you order the right part the first time.
Manual Section: Working Operations p. 112Temperature gauge climbing in hot work
Chaff packed into the radiator screen and a low coolant level show up as a rising gauge on a hot baling day. The Maintenance section lists cooling system capacity at 9 L for the T4.55S and T4.65S and 11 L for the T4.75S, so a refill is measured rather than topped off blind.
Manual Section: Maintenance p. 121Frequently Asked Questions
Which tractors does this manual cover?
The cover on page 1 lists the New Holland T4.55S, T4.65S and T4.75S. It is the factory operator manual, part number 51519607, 234 pages in English. Page 16 of the General Information section shows where the tractor chassis number and the certification plate are located, so you can match your tractor before buying. p. 1
Does it give fuel filter service intervals?
Yes. The Maintenance section sets fuel filter replacement and feed pump cleaning at every 300 hours, and cleaning of the fuel filter sediment bowl at every 50 hours. The rest of the hour-based intervals sit in the same maintenance chart. p. 122
Will it help me chase down a fault?
The Troubleshooting section starts with locating the faulty area, then gives tables for the engine, electrical system, hydraulic systems, rear three-point hitch, hydraulic service brakes and cab climate control. This is operator-level fault finding, not component teardown. p. 169
Are fluid capacities listed?
Yes. Fuel tank capacity is 82 L and the powershuttle transmission takes 35 L. Crankcase oil capacity, unfiltered, is 7.9 L on the T4.55S and T4.65S and 9.3 L on the T4.75S. All of it sits in the Maintenance section. p. 121
Is this New Holland T4.55S manual a PDF I download?
Delivery is instant: a 234-page searchable PDF is yours the second checkout clears. Laptop, tablet, or phone, all fine.
Can I print a copy of this New Holland T4.55S Operator Manual for the shop?
You can. The PDF is unlocked and carries no copy protection, so print the sections you want and keep the file as your backup.
