Part of the New Holland Repair Manuals.
From the pickup tines to the knotter frame, this service manual walks every working system of the New Holland BB9050, BB9060, BB9070, and BB9080 big balers from serial number 4700 and up: the electrical and electronic systems with fault codes, main drive gearbox, pickup, packer, rotor and stuffer feeding, crop cutter, plunger and density system, and the twine tying mechanism.
When a knotter starts throwing loose bales at dusk and the dealer closed an hour ago, there is nobody to ask. These 887 pages are the answer: teardown and assembly procedures, adjustments, torque values, gearbox oil capacities, and troubleshooting tables from New Holland publication 87491717A, the same book their own technicians use.
It is a PDF, so it lives on the laptop in the truck or the phone in your pocket. Wherever the baler stops, the book is already there, and the hay does not wait.

New Holland BB9050, BB9060, BB9070, BB9080 Common Problems This Manual Covers
Knotter misties and broken twine
A knotter that drops one string per bale can cost a whole afternoon of rebaling. The manual covers the complete knotter system, twine routing, knotter drive gearbox, knotter frame service, and twine tension adjustments so you can find whether the fault is in the billhook, the twine disc, or simply tension.
Manual Section: Wrapping and Tying Twine Tying p. 734Fault codes on the baler monitor
Electronic faults stop these balers as surely as a broken shaft, and guessing at a code wastes daylight. The Distribution Systems section documents the electrical power system, electronic system, and fault codes so you can trace a code to the actual sensor or harness at fault.
Manual Section: Distribution Systems p. 22Stuffer trips out of time
A stuffer that mistimes or fails to trip leaves wads in the precompression chamber and a plugged feed path. This section walks the stuffer overview, tripping system, stuffer brake check, shuttle feeder, and dedicated stuffer troubleshooting.
Manual Section: Feeding Stuffer p. 624Pickup tines snapping in heavy windrows
Bent gauge wheels, poor flotation, and a slipping reel drive clutch all show up first as broken tines and skipped crop. The pickup section covers operating width, flotation, gauge wheels, the reel drive system, slip clutch service, and tine replacement.
Manual Section: Picking Picking Up p. 477Inconsistent bale density and banana bales
Uneven or soft bales usually trace back to the density system or worn plunger components. The pressing section covers the density system, plunger specification and overhaul, side hay dogs, and the top compression plate.
Manual Section: Pressing Square Bale Pressing p. 674Crop cutter knives not engaging
When the knife drawer will not raise or knives hang up in the slots, the fault is usually hydraulic. This section includes the blade control circuit, knife engagement system, control valve, cylinder disassembly, and the hydraulic schema for the cutter.
Manual Section: Chopping Crop Cutter p. 656Torque limiter slipping under load
A driveline torque limiter that slips in heavy crop starves the whole machine of power and burns itself out fast. The Power Production section covers torque limiter service so you can inspect and rebuild it instead of replacing it blind.
Manual Section: Power Production p. 343Frequently Asked Questions
