NOTE: The ports on the manifold are marked for easy
identification of components. Example: SV1 is the deck

(See Hydraulic Schematic to identify the function of the
hydraulic lines and cartridge valves at each port loca-
tion).
Thecontrolmanifoldsforthethreecuttingdecksections
are very similar. Note: When servicing the deck control
manifolds, DO NOT interchange parts from one control
manifold to another.
For solenoid and control valve service procedures, see
Hydraulic Control Manifold Service: 4 Wheel Drive in
this section. Refer to Figure 57 for cartridge valve and
plug installation torque.
