Section 3 - MAINTENANCE 

 

3.1 INTRODUCTION 

To retain the quality of the Tractor, use genuine 
SNAPPER replacement parts only.  Contact a local 
SNAPPER dealer for parts and service assistance. For 
the correct part or information for a particular Tractor, 
always mention the model and serial number. 
SNAPPER recommends returning the Tractor to an 
authorized SNAPPER dealer annually for inspection 
and addition of any new devices, which might upgrade 
the safety of the Tractor.  For the nearest SNAPPER 
dealer in your area, check the yellow pages under the 
heading LAWN MOWERS. For engine parts and 
service, look for the engine manufacturer’s dealers 
under the heading, ENGINES - gasoline. 

 

3.2  SERVICE - AFTER FIRST 5 HOURS

service with the engine or blades running. STOP blades. 
STOP engine.  Set park brake. Remove key. Remove 
spark plug wire from spark plug and secure wire away 
from spark plug. Engine and components can be 
extremely hot. Avoid burns by allowing engine and 
components sufficient time to cool.
