NOTE: The ports on the PTO manifolds are marked for
easy identification of components. Example: SV1 is the
deck solenoid valve and P1 is a gear pump connection
port (see Hydraulic Schematic in Chapter 10 -- Foldout
Drawings to identify the function of the hydraulic lines
and cartridge valves at each manifold port).
The PTO control manifolds for the three (3) cutting deck
sections are very similar.
IMPORTANT: When servicing the PTO manifolds,
DO NOT interchange parts from one control man-
ifold to another.
Removal (Fig. 96)
1. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of this section.
2. To prevent contamination of hydraulic system during
manifold removal, thoroughly clean exterior of manifold
and fittings.
3. Disconnect wire harness connector from the sole-
noid valve.
4. Disconnect hydraulic lines from manifold and put
caps or plugs on open hydraulic lines and fittings. Label
disconnected hydraulic lines for proper installation.
NOTE: The upper cap screw on the right side PTO
manifold also secures the ground cable and has a lock
washer to ensure a good grounding path. Make sure
that lock washer is retrieved when removing RH PTO
manifold from frame.
5. Remove hydraulic PTO manifold from the frame us-
ing Figure 96 as guide.
6. If hydraulic fittings are to be removed from manifold,
mark fitting orientation to allow correct assembly. Re-
move fittings from manifold and discard O--rings.

Installation (Fig. 96)
1. If fittings were removed from manifold, lubricate and
place new O--rings onto fittings. Install fittings into man-
ifold openings using marks made during the removal
process to properly orientate fittings. Tighten fittings
(see Hydraulic Fitting Installation in the General Infor-
mation section of this chapter).
2. Install hydraulic PTO manifold to the frame using Fig-
ure 96 as guide.
NOTE: Make sure that lock washer and ground cable
are positioned under upper cap screw head when instal-
ling RH PTO manifold.
3. Remove caps and plugs from fittings and hoses. Us-
ing labels placed during manifold removal, properly con-
nect hydraulic lines to manifold (see Hydraulic Hose and
Tube Installation in the General Information section of
this chapter).
4. Connect wire harness connector to the solenoid
valve coil on the PTO manifold.
5. Make sure hydraulic tank is full. Add correct oil if nec-
essary before returning machine to service.
