Part of the New Holland Repair Manuals.
Net wrap quits halfway through a bale with a field of dry hay behind you; the 629-page New Holland BR6090 Combi service manual PDF, factory document 87711078B, is what gets this round baler tying again. Wiring diagrams follow each circuit from the electronic control back through the harness, while hydraulic schematics map the secondary power system and the pneumatic brake lines on pulled-type setups. Fault code tables match a display reading to the sensor that set it, and crop processing fills the longest stretch of the book: pickup, rotor feeding, crop cutter, chain pressing, net and film wrapping. Set your right hand tailgate sensor at 5 to 11 mm; torque a 1/2 in BSP hydraulic adapter to 102 Nm. A guessed fitting torque is a hose that lets go under pressure. Bookmarked and searchable, and the pages print clean enough to take to the bench and get greasy.

New Holland BR6090 Combi Common Problems This Manual Covers
New Holland BR6090 Combi actuator stalls mid bale and the wrap cycle stops
Pull the active error list through the diagnostic screens before touching anything. Free the jammed actuator by hand, then confirm the duckbill recall spring eyebolt measures 70 mm (2.75 in) as specified on page 556. Check the secondary spring at 190 mm (7.48 in) on page 557 and reset brake timing clearance to 10 mm (0.393 in).
Manual Section: Electrical Power System Diagnostic ProcessMonitor shows tailgate open even after the door latches and the cycle will not advance
Inspect the right hand tailgate sensor first. Set its clearance inside the 5 to 11 mm (0.2 to 0.4 in) window listed on page 108, then clean the target face of packed chaff and dried film. Back-probe the connector for green corrosion and chase the circuit on the wiring diagram before condemning the sensor.
Manual Section: Tailgate TroubleshootingNet or plastic will not cut after wrapping and has to be cut by hand from the tractor seat
Clear the duckbill and knife area of wound crop, then set knife height to 17 mm (0.669 in) above the mounting plate edge per page 548. Hold striker plate clearance at 1 to 2 mm (0.0393 to 0.0787 in) off the knife lower edge, page 549. Verify the knife cylinder extends 6 mm (0.236 in) from fully retracted.
Manual Section: Knife Engagement System Troubleshooting p. 548Bale density reads erratic during pressing and bales come out soft or barrel shaped
Test the density sensor output with the chamber empty. It should sit near 0.35 V, with 0.293 V minimum and 1.074 V maximum as charted on page 540. Fit the 40 mm calibration spacer and recheck the full chamber value against the 2.8 to 3.05 V optimum band. Clean and reseat every loom connector before recalibrating.
Manual Section: Electrical Power System Diagnostic Process p. 540Net slips over the metering roll or feeds unevenly, wraps come out loose and ragged
Confirm the net roll measures 1200 to 1300 mm (47 to 51 in) wide with a 75 mm (2.95 in) cardboard core, page 546. Spin the metering roll by hand and free any drag from wound film. Reroute the net exactly as shown, then set the stop bolt distance W to 55 mm (2.16 in) on page 556.
Manual Section: Net/Film Wrapping p. 546Wrapper quits during the bale end cycle and needs manual recovery every few bales
Start at the battery side. Check the 80 A fusible link and the 30 A main rail fuse listed on page 143, then load test the supply with the PTO turning. Verify the tractor pump delivers at least 25 L/min (6.6 US gpm) or the satellites will stall out. Torque loose hydraulic adapters to spec on page 17 and get back baling.
Manual Section: Electrical Power System Fault CodesFrequently Asked Questions
What are the torque specifications for hardware on the New Holland BR6090 baler?
The minimum hardware tightening torques vary by size and grade. For example, a 1/4 inch SAE Grade 5 unplated bolt requires 9.7 Nm (86 lb in), while a 1.0 inch SAE Grade 8 plated bolt requires 1356 Nm (1000 lb ft). p. 14
How do I clear an error code on the New Holland BR6090 Combi?
System errors can be displayed at the moment they occur or can be suppressed. If suppressed, the warning indicator appears in the indicator box, but the error message does not appear on the screen. Active errors are retained until resolved. p. 109
What is the procedure for adjusting the pick-up flotation spring on the BR6090?
Adjust the pick-up flotation spring so that a force of 300 N (30 kgf) applied at the pick-up gauge wheel brace will begin to lift the pick-up. This is a starting point, and further adjustment should be carried out in the field depending on terrain conditions. p. 392
What is the required oil flow for the baler wrapper hydraulic system?
The front valve mounted to the right hand side of the baler must have a minimum flow of oil 26 l/min (6.9 US gpm) to control the wrapper, crop cutter knives, and duckbill movements. p. 72
What is the tightening torque for the cone clamp on the PTO shaft of the New Holland BR6090 Combi round baler?
The tightening torque for the cone clamp on the PTO shaft must be at least 100 Nm (73.8 lb ft). p. 258
What exactly do I receive with this New Holland BR6090 Combi Service Manual?
A single searchable PDF file of 629 pages, downloadable right after payment. Nothing ships, nothing waits in the mail.
Is printing allowed for this New Holland BR6090 Combi Service Manual?
Yes, print as many copies as you want, and there are no restrictions. Many mechanics print the section they need and bring it to the shop floor.
