I am asking for my husband...he has a Danuser F7 auger and it needs oil. We talked to the Danuser dealer and was told that the older model we have needed to use John Deere corn head grease. My husband says this auger has weep holes (my name for them) that once the oil/grease is full the weep holes will start weeping. This tells you it is full, but my husband says the grease would be too thick to come out of the weep holes so he is concerned that this auger really doesn't use corn head grease. Any knowledge on what a Danuser f7 auger uses? oil or grease? Thank you for your help!
