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.
