Part of the New Holland Repair Manuals.
This is the factory service manual for the New Holland L221 and L228 skid steer loaders and the C227 and C232 compact track loaders, all Tier 4B (final) machines. It is one book for both families because they share the engine, the hydrostatic drive, the loader and the electrical architecture, and it splits the ground each machine does not share into its own chapters: wheels for the skid steers, tracks and track suspension for the track loaders. Roughly two thirds of the manual is electrical, most of it harness drawings, connector diagrams and the fault-code tables with the schematic and the guided test behind each code.
