This is the factory service manual for the New Holland Boomer 40 and Boomer 50 compact tractors with cab, part number 48017703. It works through the tractor system by system and treats the hydrostatic drive as its own section rather than folding it into the transmission. The hydraulic section gives the figures that matter on the bench: an open-centre gear pump system with a stated capacity, the two relief settings, the lift capacity at the ball ends and the flow the pump must still make under load.
