Part of the New Holland Repair Manuals.
This is the factory service manual for the New Holland Boomer 41 and Boomer 47 compact tractors, the Tier 4B Final machines rated 40.2 and 45.6 gross horsepower at 2600 RPM. It covers teardown and repair of the engine, clutch, both the gear and hydrostatic transmissions, powered front axle, rear axle and planetary final drives, PTO (mechanical and electro-hydraulic rear control), brakes, steering, wheels, cab heating and A/C, and the hood and platform sheet metal. The hydraulic chapters include the fixed displacement pump, three-point hitch control valve, and separate schematics for gear and HST models. Electrical coverage includes the starting system, fuel tank system, and full wiring diagrams as individual sheets plus composite schematic sets.
