A hydraulic system (56) includes a variable-displacement first pump (68A, 68B, 68C, 68D) and a variable-displacement second pump (68A, 68B, 68C, 68D). The hydraulic system also includes a first actuator (26, 32, 34) selectively connected either to the first pump in a closed loop manner and not the s...
