Power is supplied by our Max Pro Series 439cc FIRMAN engine which runs cool and efficient thanks to its Phoenix Fat Head Block. Our Whisper Series muffler keeps the H05751 running at a quiet 74 decibels – well below the standards set by the National Parks Service, and our spark arrester has been approved by the USDA Forest Service.
