NOTE: The ports on the manifold are marked for easy
identification of components. Example: SV1 is the deck
solenoid valve and P1 is the gear pump connection port.
(See Hydraulic Schematics to identify the function of the
hydraulic lines and cartridge valves at each port loca-
tion).
The control manifolds for the three cutting decks are
very similar. Note: When servicing the deck control
manifolds, DO NOT interchange parts from one control
manifold to another.
