Hi guys, new here to the forum. Wondering if anyone here could tell me what model of HD21 this is and the approximate year? Would this be a HD21P?         |

Somebody will know, or you could broom off some snow and find the ID tag. ------------- "If at first you don't succeed, get a bigger hammer" Allis Express participant |

| I will place a guess as to a later unit, a few reasons, Power Shift transmission, later Farr Dynacell Air Cleaner unless had been upgraded by a dealer which usually did not happen. mid 70s perhaps? |

| HD21P is the correct model- was produced from 1963-69. |

Thanks guys, I did look around some for a tag on it and didn't find one. Where on the machine should it be located? |

yep HD21P; farr air cleaner and 2speed F/R trans. Looks like you got a winch hidden in there too; most likely a Carco J120ps ------------- tits tyres and tracks they all cost you money |

Newer models from the 70s would be the 21B and 21C which would have a 3 speed trans and replaceable paper cartridge barrel air filter. ------------- Like them all, but love the "B"s. |
