chine. Take care to not damage fuel lines, hydraulic
hoses or electrical components as assembly is raised.
Support mount plate assembly in a raised position to al-
low access to machine components.
4. If additional clearance below the tank mount plate
assembly is desired, the suction hose can be clamped
and disconnected from the gear pump:
A. Clamp suction hose to prevent draining the hy-
draulic tank.
B. Thoroughly clean junction of suction hose and
gear pump inlet fitting.
C. Disconnect suction hose from gear pump inlet fit-
ting.
D. Carefully raise and support the tank mount plate
assembly.
5. After completing service work below the tank mount
plate assembly, carefully lower assembly to machine
frame. Secure assembly tof rame with removed screws.
If suction hose was disconnected from gear pump, con-
nect hose to pump fitting and secure with hose clamp.
Remove Tank Mount Plate Assembly (Fig. 16)
1. Parkmachine on alevel surface,engage theparking
brake, lower the cutting units and stop the engine. Re-
move key from the ignition switch.
2. Completely drain hydraulic oil from hydraulic reser-
voir through gear pumpsuction hoseinto a suitable con-
tainer.
3. Disconnecthydraulichosesfrom fittingson hydraulic
tank. Put clean caps or plugs on hoses a nd fittings.
4. Close fuel shut off valve on f uel tank.

moved screws.
B. Connect and secure all hydraulic hoses (see Hy-
draulic Hose and Tube Installation in the General In-
formation section of Chapter 5 -- Hydraulic System).
C. Connect and secure all fuel hoses. Open fuel
shut off valve on fuel tank.
D. If machine is equipped with the Turf Guardian
