Check engine oil daily and after every 4 hours of operation.
Machine must be setting level when checking oil. Refer to
engine manual and maintenance schedule for oil
recommendation and capacities.
Change the engine oil and filter after the first 5 hours of
operation and per the engine manufacturer’s recommendations
after that. If mower is being operated in extremely dirty
conditions, then it is recommended oil be changed more
frequently.
