Maintenance Service Intervals
It is very important to keep good maintenance records. Use the hour meter on the mower and record
the hour reading of each maintenance service so you will not forget how long it has been since you
last did certain maintenance. The more faithful and consistent you are, the longer the mower will
last and slower it will depreciate.
