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 acti-
vated.
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 link-
age rods moving into the holes in the lap bars.
This lap bar Neutral lock mechanism also acti-
vates 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 deter-
mining 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 length-
ening 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
relocating 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 Neu-
tral positions, the ZTM should not creep (I.E.,
move in the Forward or Reverse directions of
travel). If this occurs, contact your Service rep-
resentative 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
location that is not subject to drastic changes
in temperature. Before storing, the following
maintenance procedures should be performed.
DANGER:
buildings or other areas where open
flames sparks, or other ignition sources
are present, (such as furnaces water
heaters, etc).
a. Clean the mower. The entire tractor and
cutting 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 pul-
leys 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 fil-
ter.
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 bat-
tery is fully charged.
i. Inspect the hydraulic hoses, lines and fit-
tings. 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).
