Part of the New Holland Repair Manuals.
Whether your 135 Ultra runs net or plastic wrap, this New Holland Roll Baler 135 Ultra service manual PDF (OEM ID 47824851) covers the whole round baler in 275 pages, main gearbox and PTO through pickup, rotor, bale formation, and ejection. Hydraulic schematics trace the main control valve and combi hydraulic system circuit by circuit, while wiring diagrams map each harness, connector, warning indicator, and alarm on the machine. Product feeding takes the largest share of the book, walking pickup and rotor repairs through to final settings. When the electrics act up, start at the 40 A main fuse; when you reseal the main gearbox, pull the bolts to an initial 180 N·m. Rotors rebuilt on guesswork get torn down twice. Bookmarked and searchable by keyword, the PDF puts the wrapper section two clicks from the cover, so the repair fits inside the baling window.

New Holland Roll Baler 135 Ultra Common Problems This Manual Covers
New Holland Roll Baler 135 Ultra bales soft and undersized, density pressure won't reach setpoint in heavy silage
Test chamber pressure with a gauge on the density circuit; it should build toward the 160 bar (2320 psi) maximum listed on page 119, with the proportional valve zero value at 130 bar (1885 psi). If pressure checks good, inspect the bale forming rolls for wear and torque roll mounting bolts to 90 N·m per page 206.
Manual Section: Pressing - Bale Formation p. 206Net wrap fails to start or film tears during wrap cycle, bales come out loose
Check net roll brake tension and clean crop buildup off the wrap knife before blaming the actuator. Inspect the knife edge and replace it if dulled or nicked. If the wrapper drive is suspect, follow the wrapper removal procedure in the Tying/Wrapping section beginning on page 220, and torque M8 mounting hardware to 24.5 N·m from the chart on page 15.
Manual Section: Tying/Wrapping/Twisting p. 220Pickup feeds unevenly and plugs at the rotor in heavy wet grass, teeth breaking off
Run the pickup at full PTO speed and watch for bent or missing teeth; replace any that wobble. Match wear parts against the exploded parts view before ordering. Check that ground speed suits the windrow, and verify PTO speed holds near 540 RPM under load; the monitor alarms below 300 RPM per page 119.
Manual Section: Product FeedingMonitor ignores density and bale size changes, PTO speed alarm sounds at normal engine RPM
Check the 40 A main fuse shown on page 111, then unplug and inspect harness connectors for corrosion, tracing circuits with the wiring diagram on page 112. Verify the alarm setpoints: the low PTO alarm trips at 300 RPM on 540 RPM machines, and the proportional valve zero value should read 130 bar (1885 psi) per page 119.
Manual Section: Electrical Systems p. 111Tailgate hangs open or latches unevenly after bale ejection, chamber loses pressure
Measure the tailgate latch clearance on both sides: distance X should be 2-3 mm and distance Y 0 mm, specified on pages 96 and 97. Adjust the latch hooks until both sides seat evenly, then cycle the tailgate several times and recheck. Inspect hinge pins and bushings for slop while the gate is raised and locked out.
Manual Section: Tailgate - Remove, Adjust, and Install p. 96Frequently Asked Questions
What are the torque specifications for the main gearbox bolts on a New Holland Roll Baler 135 Ultra?
The main gearbox bolts (8) should be tightened in two stages. First, tighten all bolts initially to a torque of 180 N·m (133 lb ft), and then tighten them to a final torque of 220 N·m (162 lb ft). p. 37
How do I enter the dealer mode on the instrument cluster?
To enter the dealer mode, press the 'Menu' button, then the 'Calibrate' button, and finally the 'Timers and speeds' button. Once in this menu, press the buttons (1) and (5) simultaneously to access additional settings. p. 118
What is the maximum allowable wear elongation for roller chains?
The maximum allowable wear elongation for most industrial applications is approximately 3%. For drives with fixed center distances or where smoother operation is required, wear should be limited to approximately 1.5%. p. 17
What is the recommended maximum bale chamber pressure for the New Holland Roll Baler 135 Ultra?
The maximum allowed bale chamber pressure is 160 bar (2320 psi). You must never exceed this pressure to avoid component failure. p. 119
What is the torque specification for the PTO shaft bolt on a New Holland Roll Baler 135 Ultra?
The bolt (11) used to secure the PTO shaft (2) to the gearbox (1) must be tightened to a torque of 150 N·m (111 lb ft). p. 39
