Part of the New Holland Repair Manuals.
This is the full factory service manual for the New Holland TF42, TF44, TF46, TX30, TX32, TX34 and TX36 combine harvesters, the same repair information a dealer technician works from. It covers the whole machine: the engine, the mechanical and hydrostatic traction gearbox, the hydrostatic ground drive, the grain and maize headers and straw elevator, the threshing cylinder and concave, the separation walkers, the cleaning shoe and fan, the grain tank and unloading, the straw chopper and chaff spreader, the working hydraulics, and a full electrical section with the wiring diagrams. Every section carries the specifications, functional adjustments, fault finding and step-by-step overhaul procedures, so you can chase a drive, header or threshing problem and put it right instead of guessing.
