How to Check the Fuel Filter
NOTE: Before you replace the fuel filter or the fuel line, the
fuel tank must be empty.
If the fuel filter is dirty, the engine will run rough and have
less performance. Remove the old filter (Figure 29). Replace
the old filter with a new filter. Use an original equipment
part. See an authorized service dealer in your area.

Check the Tires
Check the air pressure in the tires. Tires with too much air
pressure will cause the unit to ride rough. Also, the wrong
air pressure will keep the mower deck from cutting level.
Recommended air pressure is 14 PSI (1 BAR) for both front
and rear tires.
