Part of the New Holland Operator Manuals.
Diesel particulate filter regeneration is where most owners get stuck, and the New Holland T4.115 operator manual PDF (OEM 47604431, 260 pages) walks that whole procedure from the programmable display, then keeps going through every other system on this tractor. Fault code tables translate what the instrument cluster is flashing into a cause and a fix, covering the hydraulic lift, three-point linkage, brakes, and cab climate control. A full maintenance chart sorts every service point by hour meter, and the specifications section prints axle and drawbar load limits so you can ballast a heavy implement correctly. Change the hydraulic circuit oil filter every 300 hours; pull the front M16 disc to hub nuts to 220 N·m (162.3 lb ft). A guessed torque costs you a wheel stud. Print the pages for the job at hand and let them get greasy on the bench; the bookmarked, text searchable file stays clean for the next season's work.

New Holland T4.115 Common Problems This Manual Covers
New Holland T4.115 three point hitch lifts fine cold, then slows or quits once hydraulic oil warms up
Check the transmission and rear axle oil level first; the hydraulic system version holds 58 L (15.3 US gal), listed on page 156. Replace the hydraulic circuit oil filter if it has 300 hours on it, per the schedule on page 157. Then recheck lift with the draft control lever backed off before harvest traffic stacks up.
Manual Section: Rear Three-Point Hitch TroubleshootingTransmission fault code on the dash, electric shuttle lever slow to respond or dead
Write down the code from the display, then match it against the error code reference starting on page 202. Cycle the shuttle lever through forward, neutral, and reverse; a worn lever switch or neutral button is the usual culprit. Also load test the battery; specifications on page 225 call for 88 A·h to 100 A·h capacity.
Manual Section: Troubleshooting p. 202Engine turns over slowly or refuses to start on cold mornings before field work
Check battery terminals for corrosion and load test the battery; specifications on page 225 list 88 A·h to 100 A·h capacity feeding a 3.2 kW or 4.2 kW starter motor. Inspect the alternator belt, due for a check every 100 hours. If cranking stays slow with a good battery, have the starter and cables tested before winter chores start.
Manual Section: Electrical System TroubleshootingBlue smoke and oil film in the turbo air pipe after hard pulling
Idle the engine at 1000 RPM for a few minutes before shutdown, per the operating procedure on page 95, so the turbocharger cools while oil still flows. Verify the crankcase is not overfilled; engine oil capacity is 8.5 L (2 US gal), listed on page 156. Service the air filter at the warning message or every 300 hours.
Manual Section: Operating Instructions p. 95Warning lamps flash and the digital instrument display goes blank while driving
Check battery ground and terminal connections first; loose grounds on open station tractors cause most display dropouts. Verify the alternator is charging; standard output is 120 A per the specifications on page 225. Match any code that appears against the error code reference beginning on page 202, and write codes down before they clear.
Manual Section: Display Warnings OverviewFrequently Asked Questions
