Part of the New Holland Repair Manuals.
Fits the New Holland DuraSwath draper header family from 421HB through 440HB, five models in all, and this 519-page service manual PDF, OEM number 48106362, is the factory book behind every one of them. Hydraulic coverage runs from the reservoir, cooler and filter stack through reel vertical and fore-and-aft positioning, the cutter control circuit and feeder engagement, with schematics that trace each circuit valve by valve. Wiring diagrams map light harnesses and connectors, reel speed and position control, and the chopping and cutting control systems, while troubleshooting charts sit inside the chapters where the fault shows up. Set hold-down clearance at 0.25 mm (0.01 in), keep cleat height at 13 mm (0.5 in), and torque upper and lower cutterbar roller bearing mounting bolts to 50.2 N·m (37.0 lb ft). Nothing stalls a cut like one missing clearance figure. Bookmarks and a live text layer put you in the right section in seconds, so your windrow keeps moving.
