Part of the New Holland Repair Manuals.
This is the full factory repair manual for the New Holland TR96, TR97 and TR98 twin rotor combine harvesters, the same service information a dealer technician works from. It covers the whole machine: the engine, the hydrostatic ground drive and traction, the grain header and feeder, the twin rotor threshing and separation, the cleaning shoe and fan, the grain tank and unloading, the straw chopper and spreader, the working hydraulics, and a full electrical section with the wiring diagrams and monitors. Every section carries the specifications, functional adjustments, fault finding and step-by-step overhaul procedures, so you can chase a threshing, feeder or electrical problem and put it right instead of guessing.
