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.
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 ensure
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 ROS systems for proper
operation.
• Check for loose fasteners.
