I would try Sandy Lake Implement. I bought them for the 616 and 620 there. HTH Tracy Martin ------------- No greater gift than healthy grandkids! |

Baldwin filters makes the only aftermarket replacement for these tractors. Baldwin # PA2347 Much cheaper than the OEM but still about 40 bucks last one I got. Hope this helps.------------- Yea, I can fix that..... |

Are they different from a 620? Here is the WIX # 42222 for an air filter for a 620, cost around $30 ------------- Unless your are the lead horse the scenery never changes!! |

Matt, I see the book is showing this filter as a replacement but that wix number does not fit an Onan engine. ------------- Yea, I can fix that..... |

| I just picked up a few off ebay for under 30 each a few months ago. Onan number is 140-1071. Ebay has been about the best bet for me. |

From what I can tell, none of the part numbers listed in this thread are correct for a 720. GB :) |

That looks nothing like the air filter for my 720. My filter has a plastic outer housing with the paper pleats in the center/middle. GB :) |

I think that the original style filter has been discontinued and they've made a spun metal adapter with the sealing ring on it to use a more traditional round air filter. At least that's what my research has shown me so far. GB :) |
