Part of the New Holland Repair Manuals.
The complete New Holland factory repair manual for the HW305, HW305S and HW325 self-propelled windrowers, part number 87576230, bound as separately numbered books 87576231 through 87576237.
Sections run from general information through engine overhaul, front mechanical drive, the hydrostatic ground drive, brakes, hydraulic systems, rear axle, climate control, a large electrical section with SPN/FMI fault codes and full wiring harness diagrams, header attachments, optional equipment and the cab.
The torque tables are machine specific, and the manual keeps HW305/HW305S and HW325 separate throughout, right down to which hydraulic manifold components each model actually carries. This is the book the dealer techs worked from, not a generic reprint.
