An agricultural spreader system includes a first hydraulic motor (28), a second hydraulic motor (30), and a valve system (52) coupled to the first hydraulic motor (28) and to the second hydraulic motor (30). The first hydraulic motor (28) is configured to be driven by a hydraulic fluid and to drive a first spreader disc (22) in rotation. The second hydraulic motor (30) is configured to be driven by the hydraulic fluid and to drive a second spreader disc (24) in rotation. The valve system (52) is configured to transition between a series flow arrangement and a parallel flow arrangement. The series flow arrangement is configured to direct the hydraulic fluid to the second hydraulic motor (30) through the first hydraulic motor (28). The parallel flow arrangement is configured to direct a first portion of the hydraulic fluid to the first hydraulic motor (28), and to direct a second portion of the hydraulic fluid to the second hydraulic motor (30).
