Abstract
An electro-hydraulic flow control system for controlling the movement of a cutting implement of a turf mower. The flow control system comprises a hydraulic system for raising and lowering the cutting implement. The hydraulic system comprises a hydraulic fluid, a hydraulic actuator, and a hydraulic pump. The control system additionally comprises an electromechanical fluid flow control system for controlling a flow of the hydraulic fluid through the hydraulic system. The electromechanical fluid control system comprises a routing valve, a float valve, a weight transfer valve, a weight transfer pressure adjustment (WTPA) valve, and a control module for control operation of the routing valve, the float valve, the weight transfer valve, and the WTPA valve to control operation of the actuator and thereby control movement of the cutting implement.
