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.
