Part of the New Holland Repair Manuals.
Every one of the 982 pages in this New Holland BB940, BB950, BB960 Repair Manual PDF (OEM #87028440) is aimed at the big square baler line, from the PTO driveline to bale ejection. Inside: factory wiring diagrams for the density system, knotter fan, and mistie indication circuits, plus hydraulic schematics for bale density, pick-up lifting, and blade control. You also get InfoView error code listings, knotter troubleshooting charts, and step-by-step main gearbox teardown and assembly procedures. Set the relief valve at 150 bar, torque the hydraulic pump screws to 10-15 Nm, and check roller chain tension at 20 mm of deflection under 100 N of force. A mistied bale costs you twine, time, and hay on the ground. Bookmarked cover to cover; search any spec by keyword and get back to baling.
