ing holes in each lap bar whenever the lap bars
are in their Neutral positions.
Note:
Both lap bars must be in their Neutral
positions for the Park brake interlock mecha-
nism to function so as to prevent lap bar move-
ment (movement that would activate the
hydrostatic pumps producing Forward or
Reverse travel rotation of the wheel motors) and
to allow the Park Brake switch to be activated.
Whenever the Park Brake is applied (I.E., the
Park brake lever moved completely rearward in
the control panel slot), the lap bars should be
secured in their Neutral positions by the linkage
rods moving into the holes in the lap bars. This
lap bar Neutral lock mechanism also activates
the Park brake switch, which allows for the
engine to be started. If the lap bars are in their
Neutral positions, and they are not “locked” so
as to prevent movement when the Park brake is
applied, then the linkage from the RTN on the
hydrostatic pumps and the lap bars must be
adjusted. This is done by determining which side
(or both) rod is not aligned to the hole in the lap
bar, then locating that side linkage rod turn-
buckle at the hydrostatic pump RTN, loosening
the jam nuts and lengthening or shortening the
linkage rod so that the rod snaps into the hole in
the lap bar.
Dampers are incorporated into the lap bar link-
age to provide smooth, non-jerkey, control
action. The damper rate can be adjusted by relo-
cating the damper - lower to reduce the damper
action, and elevate to increase.
Note:
The engine should be able to be started
whenever the Park Brake is applied, and the lap
bars are locked in their Neutral positions - if not,
the switch may need to be adjusted or replaced.
Whenever the ZTM is on level ground with the
engine running and the lap bars in their Neutral
positions, the ZTM should not creep (I.E., move
in the Forward or Reverse directions of travel). If
this occurs, contact your Service representative
for the procedure to reset the RTN mechanism
on the hydrostatic pumps. If the hydrostatic
pump RTN is adjusted, the control linkage must
also be readjusted.
H. Storage
1. General: If your mower will not be in service for
a few months, it should be stored in a dry loca-
tion that is not subject to drastic changes in tem-
perature. Before storing, the following
maintenance procedures should be performed.
Note:
For E.F.I. Tanks, disconnect the nega-
tive lead of the battery for storage of 4 weeks or
more.
a. Clean the mower. The entire tractor and cut-
ting deck should be washed and cleaned.
b. Sharpen the blades so that the mower will be
ready to use when needed.
c. Protect the metal surfaces. Repair scratches
with the appropriate touch-up spray paint.
Brush a rust preventive oil on any unpainted
surfaces including the pulleys and blades.
(Be careful not to get any oil on the drive
belts.)
d. Lubricate the mower.
e. Drain the engine oil. The engine should be
warm so that all the oil drains. Replace the
engine oil filter and refill the crankcase with
fresh oil.
f. Gasoline Engine: Drain all the fuel. Close the
fuel tank shutoff valve. Disconnect the fuel
line from the carbuetor and put the end into
an approved fuel container. Open the fuel
tank shutoff valve and drain the fuel tank and
line into the approved container. Replace the
fuel line on the carburetor. Start the engine
and allow it to run out of fuel. This will prevent
gum and varnish deposits from forming.
Replace the fuel filter.
g. Gasoline Engine Only: Remove the spark
plugs and pour approximately one ounce of
oil into each cylinder. Crank the engine one
or two turns to spread the oil evenly on the
cylinder walls. Replace the spark plugs.
h. Disconnect, clean and make sure the battery
is fully charged.
i. Inspect the hydraulic hoses, lines and fittings.
Replace as necessary.
j. Jack the mower up and store it on blocks to
take the weight off of the tires.
2. To Put the Mower Back in Service:
a. Check the battery. Charge if necessary.
b. Gasoline Engine Only: Remove the spark
plugs and wipe them off. Using the starter,
crank the engine to pump the excess oil out
of the spark plug holes. Replace the spark
plugs and the ignition leads. Refill the fuel
tank with fresh gasoline.
c. Check the level of the oil in the crankcase
and the hydraulic tank.
d. Lower the mower off the block and check the
tire pressure.
e. Push the mower outdoors and start the
engine. Let the engine idle until it has
warmed up completely (4 to 5 minutes).
