(1) Tilt control lever (2) Lift control leverTilt control lever (1), lift control lever (2) are controlled manually by the operator. The control levers send electronic signals to the implement electronic control module (ECM). Then, the implement ECM sends the appropriate amount of current to the solenoid valve (pilot proportioning) on the pilot valve (oil manifold). The solenoid valve sends a low-pressure signal to the main control valve. This signal causes a stem in the main control valve to move. Then, pump supply oil is sent to the implement cylinders. The cylinder rods will extend or the cylinder rods will retract.The electrohydraulic control levers are equipped with soft detents. The soft detents do not hold the lever in place. The soft detents require an increased force near the end of lever travel in order to initiate the kickout. The soft detents are controlled by the software within the implement (ECM). As the control lever is moved into the detent position and released, the linkage will travel to a kickout position that is preprogrammed. The lever should be released in order to allow automati return to the HOLD position. The linkage movement will continue until the kickout is reached. Any 6° movement of the control lever from the HOLD position will disable the soft detents. The soft detents will not be activated if the control lever is held in the detent
