Abstract

A hydraulic system for providing hydraulic power to the work implements and subassemblies on an earth-moving machine such as a loader includes a first hydraulic pump and a second hydraulic pump. The first hydraulic pump can be associated with a lift circuit including a lift arm that can be raised and lowered with respect to the machine. The second hydraulic pump can be associated with both a tilt circuit for tilting a bucket pivotally connected to the lift arm and a steering circuit for steering the machine. The lift circuit and the tilt and steering circuits can be operated concurrently and independently of each other due to the arrangement of the first hydraulic pump and the second hydraulic pump.
