GENERAL RECOMMENDATIONS
The warranty on this tractor does not cover
items that have been subjected to operator
abuse or negligence. To receive full value
from the warranty, operator must maintain
tractor as instructed in this manual.
Some adjustments will need to be made pe-
riodically to properly maintain your tractor.
At least once a season, check to see if
you should make any of the adjustments
described in the Service and Adjustments
section of this manual.
At least once a year you should replace
the spark plug, clean or replace air filter,
and check blades and belts for wear. A
new spark plug and clean air filter assure
proper air-fuel mixture and help your en-
gine run better and last longer.
BEFORE EACH USE
1. Check engine oil level.
2. Check brake operation.
3. Check tire pressure.
4. Check operator presence and
ROS systems for proper operation.
5. Check for loose fasteners.

IMPORTANT: Do not oil or grease the pivot
points which have special nylon bearings.
Viscous lubricants will attract dust and dirt
that will shorten the life of the self-lubricating
bearings. Ifyou feel they must be lubricated,
use only a dry, powdered graphite type
lubricant sparingly.
