Raise Tank Mount Plate Assembly
1. Park machine on a level surface, engage the parking
brake, lower the cutting units and stop the engine. Re-
move key from the ignition switch.
2. Locate and remove four (4) screws that secure tank
mount plate to frame.
3. Carefully lift tank mount plate assembly (hydraulic
reservoir, fuel tank and tank mount plate) up from ma-
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 to frame 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
1. Park machine on a level surface, engage the parking
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 pump suction hose into a suitable con-
tainer.
3. Disconnect hydraulic hoses from fittings on hydraulic
tank. Put clean caps or plugs on hoses and fittings.
4. Close fuel shut off valve on fuel tank.
5. Disconnect additional fuel system hoses:
A. On Greensmaster 3300 machines, disconnect
hoses from fuel filter and check valve that are located
next to rear cylinder head (Fig. 16). Also, remove
cable tie that secures hose from carbon cannister to
rear frame tube under tank mount plate.

B. On Greensmaster 3400 machines, disconnect
fuel supply hose from shut off valve on fuel tank and
fuel return hose from hose splicer fitting above radia-
tor. Also, remove vent hose from grommet in engine
support.
6. If machine is equipped with the Turf Guardian
Leak Detector System, disconnect wire harness con-
nectors from oil level sensor and solenoid coil.
7. Remove four (4) screws that secure tank mount plate
to frame.
8. Lift tank mount plate assembly (hydraulic reservoir,
fuel tank and tank mount plate) from machine.
9. After completing service work below the tank mount
plate assembly, install assembly to machine:
A. Carefully position tank mount plate assembly to
machine frame. Secure assembly to frame with re-
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
Leak Detector System, connect wire harness con-
nectors to oil level sensor and solenoid coil.
E. Fill hydraulic reservoir with new hydraulic oil.
