1996 Kinze 840 Grain Cart.  Holds over 800 bu.  We bought this cart about 7 years ago and put a new roll over tarp on it at the time and added roll over arches.  There are no holes.  The vertical auger was replaced before we bought it and the additional supports were welded on the vertical auger at that time (visible in picture).  We have patched a couple holes in the vertical auger but that is all we have done.  The dent in the upper right corner was there when we bought it and it does not leak.  We have kept this in the shed when not in use and always cleaned out the bottom very well. Tires are 305.L-32 (one has a slow leak).  Overall it has been a great cart for us.  Just upgrading to a larger one. Txt or email with questions.
