Removal (Fig. 63)
1. Park machine on a level surface, engage parking
brake, lower cutting units and stop the engine.
2. Remove left side cover next to operator seat to allow
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. Thoroughly clean hydraulic hose ends and fittings on
mow control manifold to prevent hydraulic system con-
tamination.
4. Label all hydraulic and electrical connections for as-
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) flange head screws (item 7) that se-
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 fittings are to be removed 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 were removed from manifold, lubricate and
place new O--rings onto fittings. Install fittings into man-
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 and plugs from disconnected hydrau-
lic lines and manifold fittings.
4. Lubricate and position new O--rings to fittings on
manifold. Use labels placed during the removal process
to properly install hydraulic lines to manifold fittings (see
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.
