Front Cylinder Removal (Fig. 59)
1. Before removing any parts from the hydraulic sys-
tem, park the machine on a level surface, engage the
parking brake, lower the cutting units, and stop the en-
gine.
Operate all hydraulic controls to relieve sys-
tem pressure and avoid injury from pressur-
ized hydraulic oil. Controls must be oper-
ated with the ignition switch in RUN and the
engine OFF. Return ignition switch to OFF
when pressure has been relieved. Remove
key from the ignition switch.
2. Label all hydraulic connections for reassembly.
3. Disconnect hose assemblies and O–rings from the
hydraulic fittings. Allow hoses to drain into a suitable
container.
4. Put caps or plugs on disconnected hoses and fit-
tings to prevent contamination.
