Removal (Fig. 63)
1. Park machine on a level surface, engage parking
brake, lower cutting units and stop the engine.
2. Removeleft sidecover nexttooperatorseattoallow
access to mow control manifold.
CAUTION
Before continuing further, read and become fa-
miliar with General Precautions for Removing
and Installing Hydraulic System Components in
this section.
3. Thoroughlycleanhydraulichoseendsandfittingson
mow control manifold to prevent hydraulic system con-
tamination.
4. Label all hydraulicand electrical connections foras-
sembly purposes.
5. Disconnect wire harness connectors from solenoid
valve and backlap switch.
IMPORTANT: Before disconnecting hydraulic lines
from the manifold fittings, make sure each hose is
labeled to ensure it can be connected to the correct
manifold fitting/port.
6. Disconnect hose and tube assemblies and remove
their respective O--rings from the hydraulic fittings. Al-
low hoses and tubes to drain into a suitable container.
Cap or plug hoses and manifold fittings to prevent con-
tamination.
7. Remove two(2)flangehead screws(item7)thatse-
cure manifold to machine frame. Remove manifold as-
sembly from the machine.
IMPORTANT: Before removing any hydraulic fit-
tings from the hydraulic manifold, make sure the
position of each fitting is observed and recorded to
ensure proper fitting installation.
8. If hydraulic fittingsare to beremoved from manifold,
mark fitting orientation to allow correct assembly. Re-
move hydraulic fittings and O--rings from manifold (Fig.
64). Discard removed O-- rings.
Installation (Fig. 63)
1. If fittings wereremoved from manifold,lubricate and
place newO--rings onto fittings.Install fittings intoman-
ifold openings making sure that fitting orientation is as
noted during removal (Fig. 64). Properly tighten fittings
(see Hydraulic Fitting Installation in the General Infor-
mation section of this chapter).
2. Position manifold assembly to the machine frame.
Secure assembly to the frame with two (2) flange head
screws (item 7).
3. Remove caps andplugs from disconnectedhydrau-
lic lines and manifold fittings.
4. Lubricate and position new O--rings to fittings on
manifold.Uselabelsplacedduringtheremovalprocess

Hydraulic Hose and Tube Installation in the General In-
formation section of this chapter).
5. Connect wire harness connectors to solenoid valve
and backlap switch.
6. Install left side cover.
