NOTE: The lift control manifolds used on Groundsmas-

mount to the machine in the same location. The Ground-
smaster 4500--D control manifolds are shown in Figure
97.
Removal (Fig. 97)
NOTE: The ports on the manifold are marked for easy
identification of components. Example: P1 is the gear
pump connection port (see Hydraulic Schematics in
Chapter 9 -- Foldout Drawings to identify the function of
the hydraulic lines and cartridge valves at each port).
1. Park machine on a level surface, lower cutting
decks, stop engine, apply parking brake and remove
