Part of the New Holland Repair Manuals.
A knotter that drops every third knot in the middle of first cutting does not wait for a dealer appointment. This New Holland BB900 repair manual, publication 86614937, is the factory shop reference for the self-powered BB900 big square baler and its Deutz F4L912 engine, delivered as a bookmarked 766 page PDF you download right after checkout.
Inside are the teardown and adjustment procedures a farm shop actually uses: knotter trip system operation and drive chain replacement, plunger bearing and rail work with factory clearance limits, pickup and feeder repair, clutch and gearbox service, hydraulic bale density valve repair, and electrical coverage from the starting circuit to the work lights.
Print the pages you need, clip them above the bench, and let them get greasy. The point is getting the baler back in the windrow before the weather turns, not keeping a book clean.
