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 main tain 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 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 
 

ROS systems for proper operation.

•  Check for loose fasteners.
