The flighting in my fertilizer auger was worn and rusted down to about an inch. I could have moved more fertilizer with a drinking straw than was going through that thing,so I took it apart and put new flighting in it. I had no idea that bolt would come out so easy or that it would slide off the shaft on the hydraulic motor as easy as it did or I would have just reached down through the outlet instead of unbolting the head and sliding it apart. The center shaft was in real good shape once I got all the old flighting cut off and got all the scale ground off of it. It should move some fertilizer now.
