Part of the New Holland Repair Manuals.
All 821 pages of this New Holland BigBaler 870, 890, 1270, 1290, 330, and 340 service manual PDF (OEM #47510960) exist to put your square baler back in the field. You get full wiring diagrams with connector pinouts and harness routing, hydraulic schematics for the bale density circuit, and a massive fault code section that walks you through mistie sensor, pickup speed, and bale drop DTCs. Inside you'll also find step-by-step procedures for the flywheel, gearbox, knotter drive, needles, plunger, and the grease lubrication system. Torque the PTO shaft bolts to 120 N·m, set the flywheel shear bolt at 25 N·m, and hold the flywheel gap to a 0.1 mm minimum. Knotter faults at baling season wait for nobody. Bookmarked chapters and a keyword-searchable text layer put you on the right procedure in seconds, on any device in the shop.
