NOTE: Refer to the Attachments & Accessories table
found on page 32 of this manual for the proper spark
plug type.
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 5/8-inch 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 22. Set the spark plug gap to
1.0 mm (0.040 in.).
Figure 22
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 right 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.
NOTE: If necessary, remove the tractor’s right-hand
side panel as instructed on page 20 before changing
the engine’s fuel filter.
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.
IMPORTANT:
The use of a pressure washer or garden
hose to clean your tractor is NOT recommended. It may
cause damage to electrical components, spindles,
pulleys, bearings or the engine. The use of water will
result in a shortened life of the tractor and reduce its
serviceability.
Lubrication
WARNING: Before lubricating, repairing, or
inspecting, always disengage PTO, set
parking brake, stop engine and remove key to
prevent unintended starting.
Deck Spindles
Grease fittings can be found on the top of each deck
spindle shaft. See Figure 23. Lubricate with 251H EP
grease or an equivalent No. 2 multi-purpose lithium
grease. Using a grease gun, apply two strokes
(minimum) or sufficient grease to flush old grease and
dirt out of the spindle shaft.
