Abstract
A hydraulic system for a vehicle adapted for operating a plurality of reel mower cutting units and for driving at least one vehicle component such as drive wheels or power steering. The vehicle carries an engine near the front of the vehicle which generates heat. The system includes a fluid reservoir located remote from the engine and near the rear of the vehicle. An input line is coupled with the reservoir, and a first pump is operatively coupled with the input line. A first motor receives fluid from the first pump for driving a reel mower, and a branched line having first and second branches receives fluid from the first motor. The first branch is a first return line extending to the reservoir. A second pump having a lower capacity than the first pump is operatively coupled with the second branch, and a second motor receives fluid from the second pump for driving the vehicle component. A second return line receives fluid from the second motor and is coupled with the input line for allowing fluid from the second motor to flow to the first pump without first flowing to the reservoir.
