Hi Mike, We put one on our R42, the instructions were vague, but we got it on. Works pretty good. Just keep in mind the 2 ft gain is horizontal. You will not gain much on height. It make your auger an end dump instead of side dump. You can cut the snoot on this also, but I was warned by the supplier to cut it in the same shape as it was shipped. leave that opening wide on the one side. Also you may want to consider the rotation of the auger adjustment as well, that is mentioned here. NDDAN has asked about clearance on the swivel u-joint shaft. I have none on our 11" auger. I think he was indicating on the 14" auger of the 6 and 7 series there may be an issue. Thanks!
