WARNING
Before performing any main­
tenance on the tractor or the
engine, the tractor must be
stopped, the PTO switch shut
Off, the Parking Brake en­
gaged, the engine stopped
and the key removed, and the
spark piug wire must be dis­

from the plug. Always let en­
gine and muffler cool down.
Failure to comply can result
in serious personal injury or
property damage.
Air Cleaner Maintenance
Following the recommended en­
gine manufacturer maintenance
schedule and service procedures
for the air cleaner on your engine
is important for good engine per­
formance and long engine life.
The air cleaner filters out dirt
and impurities from the air before
it enters the carburetor and mixes
with the fuel. The air cleaner must
be cleaned regularly and re-assem-
bled properly. The following air
cleaner information is a brief
overview— for detailed instruc­
tions and recommendations, see
the engine manufacturer literature
that was supplied with your en­
gine. Note: Service the air cleaner
system at more frequent intervals
than recommended if your tractor
is operated under very dusty or
dirty conditions.
Kohler 12.5HP / 14HP Engines
Kohler engines have a dual ele­
ment air cleaner design— an outer
foam pre-cleaner and an inner
paper cartridge element. Refer to
Figure 5-8 to see the components.
Check the air cleaner daily or be­
fore starting the engine.
Service Schedule—
Outer Foam Pre-Cleaner: Wash
and re-oil the pre-cleaner every 25
hours of operation or more often
under extremely dusty or dirty
conditions.
Inner Paper Cartridge Element:
Check the paper element every 100
operating hours. Clean or replace
the element as necessary.
Cleaning Instructions—
1. Remove the air cleaner cover re­
taining knob, the external cover,
and the paper element with sur­
rounding foam pre-cleaner. See
Figure 5-8.
2. Remove the foam pre-cleaner
from the paper element.
3. Wash the pre-cleaner in warm
water with detergent. Rinse thor­
oughly. Squeeze out (do not
wring) all excess water. Air dry.
4. Saturate pre-cleaner with new
engine oil. Squeeze out all excess
engine oil.
5. Reinstall pre-cleaner over the
paper element and reassemble the
components (unless the paper ele­
ment also needs cleaning which is
described next).
6. Gently tap paper element against
a solid vertical surface to dislodge
dirt and dust. Do not wash this el­
ement or use pressurized air to
clean it, as this will damage the
element. Replace a dirty, bent or
damaged element.
7. Carefully wipe off the base on
which the filters sit.
8. Reassemble all components as
shown in Figure 5-8. Remember
to carefully read the engine manu­
facturer’s literature for additional
procedures and requirements.
