and damage to the seals and bearings caused
by excessive water pressure. Ensure that the
radiator and oil cooler are kept free of dirt or grass
clippings. After cleaning, inspect the machine for
possible hydraulic-fluid leaks, damage, or wear to the
hydraulic and mechanical components, and check the
mower-deck blades for sharpness.

After Operation

After Operation Safety

•
Clean grass and debris from the cutting units,
mufflers, and engine compartment to help prevent
fires. Clean up oil or fuel spills.
•
If the cutting units are in the transport position, use
the positive mechanical lock (if available) before
you leave the machine unattended.
•
Allow the engine to cool before storing the machine
in any enclosure.
•
Remove the key and shut off the fuel (if equipped)
before storing or transporting the machine.
•
Never store the machine or fuel container where
there is an open flame, spark, or pilot light, such
as on a water heater or on other appliances.
•
Keep all parts of the machine in good working
condition and all hardware tightened, especially
blade-attachment hardware.
•
Replace all worn or damaged decals.
Pushing or Towing the
Machine
In an emergency, you can move the machine
forward by actuating the bypass valve in the
variable-displacement hydraulic pump and pushing or
towing the machine.
Important:
Do not push or tow the machine faster
than 3 to 4.8 km/h (2 to 3 mph) If you push or tow
at a faster speed, internal transmission damage
may occur.
The bypass valves must be open whenever you
push or tow the machine.
1. Raise the seat and locate the bypass valves,
which are located below the front of the fuel tank
(Figure 38).
1. Bypass valve (2)
2. Rotate each valve 3 counter-clockwise turns to
open and allow the fluid to bypass internally.
Note:
Do not open more than 3 turns. Because
the fluid is bypassed, the machine can be slowly
moved without damaging the transmission.
3. Push or tow the machine.
4. Finish pushing or towing the machine and close
the bypass valves. Torque the valve to 70 N∙m
(52 ft-lb).
Important:
Ensure that the bypass valve is
closed before you start the engine. Running
the engine with an open bypass valve causes
the transmission to overheat.
Important:
If you must push or tow the machine
in reverse, bypass the check valve in the 4-wheel
drive manifold.
To bypass the check valve, connect a hose
assembly to the reverse traction pressure test port
(located on the hydrostat) and on the port located
