• Reinstall the precleaner over the paper element.
• Reinstall the air cleaner cover and tighten the knob
securely.
Service Paper Element
The paper element should be replaced at least every
100 hours of operation. Replace more frequently if the
tractor is operated under extremely dusty conditions.
To replace the paper element, proceed as follows:
• Loosen the air cleaner cover knob and remove the
cover.
• Remove the wing nut and element cover. Then
remove the air cleaner element with precleaner.
Remove the precleaner from the element and
service as instructed earlier in this section.
IMPORTANT: Do not wash the paper element or use
pressurized air, as this will damage the element.
Examine the element and discard if dirt and/or damage
is present.
NOTE: Handle new elements carefully; do not use if
the sealing surfaces are bent or damaged.
• If any loose dirt or debris fell on the air cleaner base
when the element was removed, carefully remove it
and wipe the base clean. Be careful that none of it
drops into the intake throat.
• Check the condition of the rubber seal on the air
cleaner stud. If condition is questionable in any
way, replace it.
• Check the air cleaner base. Make sure it is secured
and not damaged. Also check the air cleaner cover
for damage or improper fit. Replace all damaged air
cleaner components.
• Install the precleaner over the new paper element.
• Install the element (with precleaner) on the base
and secure it with the wing nut.
• Install the seal onto the stud, then install the
element cover and secure with the wing nut.
• Reinstall the cover and tighten the knob securely.
Spark Plug(s)
Every 200 hours of operation, remove the spark
plug(s), check condition, and reset the gap or replace
with a new plug(s) as necessary.
• Lift the tractor’s hood and locate the spark plug wire
on the front, right area of the engine.
• Carefully pull the spark plug wire boot off of the
spark plug.
• Before removing the spark plug, clean the area
around the base of the plug to keep dirt and debris
out of the engine.
• Using a ratchet with a spark plug socket, remove
the spark plug and check its condition.
• Replace the plug if worn, dirty of damaged. Reuse
only after resetting the gap as instructed in the
following steps.
NOTE: Do not clean the spark plug in a machine
using abrasive grit. Some grit could remain in the spark
plug and enter the engine causing extensive wear and
damage.
• Check the gap using a feeler gauge and adjust, if
necessary, by carefully bending the ground
electrode. See Figure 18. Set the spark plug gap to
.030 in. (.76 mm).

• Reinstall the spark plug into the cylinder head.
Torque the spark plug to 38.0/43.4 N·m (28/32 ft.
lb.).
• Place the spark plug wire boot over the spark plug
and press until you feel it “click” in place.
Fuel Filter
WARNING: Do not replace the fuel filter
when engine is hot.
The engine is equipped with an inline fuel filter located
on the left side of the engine.
Visually inspect the filter periodically for a build-up of
residue inside the filter body, and for a dirty element
which can be indicated by discoloration. Replace the
fuel filter when dirty.
Cleaning the Engine And Deck
Any fuel or oil spilled on the machine should be wiped
off promptly.
Do NOT allow debris to accumulate around the cooling
fins of the engine or on any other part of the machine,
especially the belts and pulleys.
Deck Wash System
Your tractor’s deck is equipped with water nozzles on
its surface as part of its deck wash system.
Use the deck wash system to rinse grass clippings from
the deck’s underside and prevent the buildup of
corrosive chemicals. Complete the following steps
AFTER EACH MOWING:
1. Drive the tractor to a level, clear spot on your lawn,
near enough to a water sillcock (spigot) for your
garden hose to reach.
