Raising the selector lever allows the implement position control spring to expand, which establishes the pivot point for the hand control lever at the position control rod. The movement of the cam against the linkage operates the control valve, maintaining the position at which the implement will be carried. The position of the implement will be determined by the position of the touch control lever on the quadrant. External Controls Touch Control Lever Operation of the lift arms is controlled by the touch control lever. The touch control lever is located on the right side of the lift cover.
Hydraulic oil flows out of the from the ram cylinder, lowering the lift arms and implement.
With the selector lever in the draft control position the lift arms and implement will be lowered to the ground as soon as the touch control lever is moved off of the upper stop. With the selector lever in position control the constant draft control is locked out by mechanical linkage. The lift arms and implement are then fully controlled by the movement of the touch control lever. Moving the touch control lever downward allows the control valve to move, under spring pressure, to the rear. With the control valve in this position, hydraulic oil flows out of the ram cylinder.
