Air filter and pre-cleaner
The Kohler engines used by Cub Cadet are equipped
with a foam pre-cleaner and a pleated paper air filter.
A dirty air filter can reduce engine power, increase fuel
consumption and make starting more difficult. The pre-
cleaner should by cleaned every 25 hours. The air filter
should be cleaned every 100 hours and replaced every
200 hours of use.
To clean the pre-filter:
1. Open the hood of the tractor. See Figure 9.3.
2. Remove the air filter cover by loosening the cover
retaining wing nut and lifting the cover off.
NOTE: The wing nut is attached to the cover and does not
come off.
3. Slide the foam filter off of the paper air filter.
4. Wash the filter with warm soapy water. Let the filter
air dry. DO NOT wring the filter out.
NOTE: Wringing the filter can tear it. Squeeze the filter, but
do not twist it.
NOTE: If the pre-filter is crumbling or brittle, replace it.
5. Pour a couple of teaspoons of motor oil on the pre-fil-
ter.
6. Work the oil through the pre-filter until it is completely
saturated.
7. Squeeze the excess oil out of the pre-filter.
8. Slide the pre-filter over the air filter.
9. Re-install the air filter cover.
10. Hand tighten the air filter cover wing nut.
