Pro-Flex 120 – Hydraulic Cylinder Testing

This bulletin describes the procedures to follow in order to test Pro-Flex 120 hydraulic cylinders to troubleshoot and identify a bypassing cylinder. A common result of a bypassing cylinder is “deck drift” where one or multiple mower decks will often fall back down when hydraulic pressure is not provided by the tractor. Following the procedures will help users to isolate and identify which cylinder is bypassing for repair/replacement.
