Reel Drive, Lower Cutting Units

The MOW pedal is depressed to start reel drive opera- tion, flow from one pump section passes through No. 3 spool section and out three lines, each leading to a lift cylinder. This actuates the lift cylinders and lowers the cutting units. Oil is returned to a three-way fitting on the No. 1 spool section through lines on the top end of each

cylinder, where it passes through the valve section and returns to the reservoir through the main return line. When the cylinders complete their travel, oil flow from the No. 3 spool section is then directed to the rear cutting unit drive motor.
