Mow Control Manifold Service
1. Makesure themanifold isthoroughly cleaned before
removing any cartridge valve.
2. If solenoid cartridge valve is being serviced, remove
nutsecuringsolenoidcoilto thecartridgevalve.Careful-
ly slide solenoid coil off the valve.
3. If flow control cartridge valve is being serviced, re-
move rotary handle from valve stem (Fig. 72):
A. Loosen two (2) set screws that secure handle
cap.
B. Remove screw and then lift handle cap from
valve.
C. Locate and retrieve detent pin, compression
spring, bushing and lip seal. The sleeve bearing
should stay in the cap.
D. Loosen two (2) set screws that secure handle
base to flow control valve and remove base.
CAUTION
Before openinghydraulic system, operateall hy-
draulic controls to relieve system pressure and
avoid injury from pressurized hydraulic oil. See
Relieving HydraulicSystemPressure inthe Gen-
eral Information section of this chapter.
IMPORTANT: Use care when removing cartridge
valves. Slightbending ordistortion of thestem tube
can cause binding and malfunction. Make sure that
deep well socket fully engages the valve base.
4. Using a deep well socket, remove cartridge valve
from manifold. Note correct location of O--rings, sealing
rings and backup rings. Remove and discard seal kit
from valve.
IMPORTANT: Before removing mow/backlap spool
from mow manifold, remove backlap switch, dowel
pin and ball.
5. If necessary, remove mow/backlap spool from mow
manifold (Fig. 73):
A. Remove backlap switch from mow manifold be-
foreremovingmow/backlap spool(Fig.74).Remove
dowel pin and ball from manifold port after switch is
removed. Remove and discard O--ring from switch.
B. Remove lower retaining ring from mow/backlap
spool. Raise mow/backlap spool to allow access to
retaining ring on upper end of spool. Remove upper
retaining ring.
C. Push spool down until O--ring and back--up ring
are exposed on bottom of mow manifold. Remove
lower O--ring and back--up ring from spool.
D. Pull spool up and out of mow manifold. Remove
O--rings and back--up ring from spool.
E. Discard removed O--rings and back--up rings.
