Here is mine. A 1978 HN 320.  I've been told by the previous owner its been turned up to 350 hp.  One word that describes these tractors is HEAVY.  Twice as much iron in this one then in a Versatile.  I always wanted a Big Bud so I bought this one just to play around with and as a collectable.  With just over 500 made they can be rare especially if you start breaking them down by model and series.  I honestly believe in the future they well be sought out more and more by big time collectors especially with all the publicity the Williams brothers are generating about Big Bud with their 747 and the new HN 320 toy they will have next year.
