i was just on a call yesterday. it was a 6 month old harman pf100 that the auger would not turn. they had burnt 25 bags og michigan wood pellets "green and white bag". there so many fine in them that it had jammed the auger. these seem like junk pellets to me.. i have never seen pellets with so many fines before. the pellets seem soft and break apart easily. they are cheaper than most buying online but it looks like you get what you pay for. if you have to go through the trouble of cleaning and screening pellets you are better off saving another 100 per ton and burn corn i just got corn for 127/ton. i think most of these are coming from pelletsales.com just wanting to put my finding out there to try to save someone else alot of headache. once you have 3-4 tons in the garage and then find out you have problems it is to late.......
