84" double auger 27" fan McKee with 37pto HP. Works great, I use it to blow plowed banks back from the snow plows. Hydrostat makes all the difference. CJ
PS I think the 60 footer has us all beat!
Before I got the blower I rented a 624H for moving banks back and I have a friend that has a 644J that I use in his pit for loading gravel. Hands down John Deere has got to be the best operating quietest loaders I have been in. [the newer ones!] CJ
