This is the factory repair manual, CNH publication 84126849, for the New Holland Boomer 3040 CVT, Boomer 3045 CVT and Boomer 3050 CVT compact tractors. The heart of the book is the CVT transmission section - the continuously variable drive unit with its hydrostatic and mechanical power paths, control valves, servo and the calibration procedures you cannot guess your way through. Around that sit full teardown coverage of the engine, front drive axle, differential, rear and mid PTO, brakes, steering, hydraulics, cab climate control and the electrical system with circuit by circuit wiring. Specification tables carry separate columns for each model, which matters because the 3040 and 3045 are rated at 2600 rpm while the 3050 runs 2800, and the pressures, flows and power figures follow that split.
