Reel Drive, Raising Cutting Units

When the LIFT pedal is depressed, No. 1, 2 and 3 spools are pushed inward. When spools pass neutral, cutting units stop operation. Holding pedal depressed keeps spools fully in. This directs flow from one pump section to pass through end cover and No. 1 spool valve, out

three lines leading to lift cylinders, causing cylinders to raise the cutting units. Oil forced out of cylinders travels through lines leading to No. 3 spool section, through the valve bank and back to reservoir through main re- turn line.
