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
Dampers are incorporated into the lap bar link- age to provide smooth,
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: Do not store machine inside 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
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).
