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
27). 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
housing from cutting level. The correct air pressure is
shown on the side of the tire.
