While operators need to check oil level and add it as necessary as well as keep up with regular scheduled maintenance, EXi Series never requires oil change. This engine, available on several lawn mowers, starts within 2 pulls and incorporates starting system (ReadyStart®) that does not require any priming or choking. While air filter that does not require any tools to change further facilitates maintenance, fuel neck is angled toward operator and sized to aid fueling.
