ABSTRACT:
A fluid circuit connects a first pump to a first motor and has a control valve for controlling fluid flow to the first motor. The control valve is movable between a first position at which the first pump is blocked from communication with the first motor, a second position at which fluid flow to the motor is controllably modulated and a third position at which substantially the full output of the first pump is directed to the first motor. A valve device connects a second pump to the fluid circuit and is movable between a first position at which the second pump is in communication with a tank and a second position at which the output of the second pump is combined with the output of the first pump. The valve device is moved to the second position in response to the control valve being moved from said second position toward said third position.
