RH DECK PTO MANIFOLD SHOWN
1. PTO manifold body
2. NWD SAE #4 plug with O- -ring
3. Orifice (0.063) (port OR)
4. #8 zero leak plug with O- -ring
NOTE: The ports on the manifold are marked for easy
identification of components. Example: S is the deck so-
lenoid valve and P1 is the gear pump connection port.
(See Hydraulic Schematic in Chapter 9 -- Foldout Draw-
ings to identify the function of the hydraulic lines and car-
tridge valves at each port location).
The control manifolds for the three (3) cutting decks are
very similar. The front deck control manifold does not in-
clude an orifice (item 3). Note: When servicing the deck
control manifolds, DO NOT interchange parts from one
control manifold to another.
