The first motor is configured to be driven by a working fluid and to drive a first spreader disc in rotation. The second motor is configured to be driven by the working fluid and to drive a second spreader disc in rotation. The valve system is configured to transition between a series flow arrangement and a parallel flow arrangement. The series flow arrangement is configured to direct the working fluid to the second motor through the first motor. The parallel flow arrangement is configured to direct a first portion of the working fluid to the first motor, and to direct a second portion of the working fluid to the second motor.
