Part of the New Holland Repair Manuals.
Three commercial mowers, one factory book: the New Holland MC22, MC28, MC35 service manual PDF, publication 604.55.081.00, covers all three models across 829 pages, so whichever one you own, the procedures fit. Wiring diagrams for the charging and starting circuits anchor an electrical section that fills nearly a third of the book, while hydraulic schematics trace the lift circuit from the control valve out to the lift cylinders. Overhaul procedures take you through the engine, the transaxle, the two-way clutch in the four wheel drive rear axle, and the PTO with its automatic disengagement system. Check that the thermostat starts opening at 176°F (80°C), then torque the ROPS mounting bolts to 157 ± 9.8 N·m when the frame goes back together. One guessed spec buys you a second teardown. Bookmarked and text-searchable, this file goes wherever the mower sits: bench, barn, or trailer.
