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 periodically to
properly maintain your tractor.
All adjustments in the Service and Adjustments section of
this manual should be checked at least once each season.
•
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 engine run better and last longer.
BEFORE EACH USE
• Check engine oil level.
• Check brake operation.
• Check tire pressure.
• Check operator presence and
interlock systems for proper operation.
• Check for loose fasteners.
