RH WING DECK PTO MANIFOLD SHOWN
1. 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 PTO manifolds are marked for
easy identification of components. Example: S is the
deck solenoid valve and P1 is the 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 port location).
The control manifolds for the three (3) cutting deck sec-
tions are very similar. The PTO manifold for the front
(center) deck does not include an orifice (item 3).
IMPORTANT: When servicing the PTO manifolds,
DO NOT interchange parts from one control man-
ifold to another.

NOTE: The PTO manifold assembly includes zero leak
plugs. These plugs have a tapered sealing surface on
the plug head that is designed to resist vibration induced
plug loosening. The zero leak plugs also have an O--ring
as a secondary seal. If zero leak plug removal is neces-
sary, lightly rap the plug head using a punch and ham-
mer before using an allen wrench to remove the plug:
the impact will allow plug removal with less chance of
damage to the socket head of the plug.
