Maintenance
WARNING
Hot exhaust system components may ignite
gasoline vapors even after the engine is stopped.
Hot particles exhausted during engine operation
may ignite flammable materials. Fire may result
in personal injury or property damage.
Do Not refuel or run engine unless spark arrester
is installed.
1.
Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2.
Wait for muffler to cool.
3.
If any breaks in the screen or welds are observed,
replace arrester.
4.
If plugging of the screen is observed, remove
arrester and shake loose particles out of the
arrester and clean screen with a wire brush (soak
in solvent if necessary). Reinstall arrester on
exhaust outlet.

“Loctite 243”, or “Fel-Pro, Pro-Lock Nut Type” are
used on the following fasteners:
•
ROPS spring pin housing.
•
Sheave and clutch retaining bolt in the end of
engine crankshaft.
•
Hydro cross member mounting bolts
Thread locking adhesives are required for some
hardware on engines — see the Engine manual.

Dielectric grease is used on all blade type electrical
connections to prevent corrosion and loss of contact.
Dielectric grease should not be applied to sealed
connectors.
Adjustments
Note:
Disengage PTO, shut off engine, wait for
all moving parts to stop, engage parking brake, and
remove key before servicing, cleaning, or making any
adjustments to the unit.
Deck Leveling
1.
Position the mower on a flat surface.
2.
Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
3.
Check the tire pressure in the drive tires. Proper
inflation pressure for tires is 13 psi (90 kPa).
Adjust if necessary.
4.
Position the transport lock in the latching
position.
5.
Carefully rotate the blades from side to side.
6.
Measure between the outside cutting edges and
the flat surface (Figure 68). If both measurements
are not within 3/16 inch (5 mm), an adjustment is
required; continue with this procedure.
