Reel Drive, Mowing Operation
The MOW pedal is depressed, which causes the No. 1,
2 and 3 spools to be positioned fully out of valve bank.
This directs flow from one pump section to pass through
left end cover and out line leading to left front cutting unit
drive motor. Flow causes motor to turn, driving reel.
Flow from separate pump section passes through No. 2
valve section and out a line to right front cutting unit
motor. Return oil from two front cutting units joins to-
gether and returns to right end of valve section, where
is passes into the main return line and flows back to
reservoir.
Flow from another separate pump section passes
through No. 3 spool section and out through a line to the
rear cutting unit drive motor. Return oil from the motor
passes through a line leading to the right hand end of
the valve bank, where it also joins with the main return
line back to the reservoir.
