Hydraulic Manifold
Removal (Fig. 45)
1. Park the machine on a level surface, engage the
parking brake, lower the cutting units, and stop the en-
gine. Remove the key from the ignition switch.
CAUTION
Operate all hydraulic controls to relieve system
pressure and avoid injury from pressurized hy-
draulic oil.
2. Raise and remove hood to gain access to the hy-
draulic manifold.
NOTE: The ports on the manifold are marked for easy
identification of components. Example: R1 is the reel cir-
cuit relief valve and G1 is the test gauge connection port.
(See Hydraulic Schematics to identify the function of the
hydraulic lines and cartridge valves at each port loca-
tion).
3. If necessary, the hydraulic manifold can be removed
(Figure 45):
A. Disconnect solenoid valve and backlap switch
electrical connectors.
B. Clean manifold and hydraulic connections. Dis-
connect hydraulic lines. Label all connections for
reassembly.
C. Allow hydraulic lines to drain into a suitable con-
tainer. Put caps or plugs on disconnected hoses and
fittings to prevent contamination.
D. Remove two flange head screws that secure bot-
tom of hydraulic manifold to the mounting bracket.
E. Support hydraulic manifold and remove flange
head screw that secures hydraulic manifold to the
cylinder support bracket. Remove hydraulic man-
ifold from the machine.

Installation (Fig. 45)
1. Secure hydraulic manifold to the cylinder support
bracket and the mounting bracket with three flange head
screws.
2. Make sure all hydraulic connections, ports, and fit-
tings are clean.
3. Remove caps or plugs that were put on any hydraulic
lines or fittings during disassembly.
4. Correctly connect hydraulic lines to the manifold.
Tighten all hydraulic fittings and connections.
5. Reconnect solenoid valve and backlap switch elec-
trical connectors.
6. Install hood.
7. Follow Hydraulic System Start–up procedures.
