    <p>The cow magnet is properly known as a rumen magnet.  I kept one
      below the filter in the hydraulic filter housing on an IH Farmall
      686.  It would always be covered in a fine metallic fuzz. 
      Happily, there was never anything larger stuck to it.</p>

          magnets here on this farm but I always knew what they were. I
          haven't priced them but I think back then (1940's and 1950's)
          they were a little $$$. I have heard of some guys sticking
          some on their baler and at the feed throat of their hammer

        <div>I don't remember off of the top of my head if any other
          critters are prone to hardware disease. A cow's mouth and nose
          is not prehensile enough to sort food well. Sheep, goats and
          horses etc. are very much so and a horse's mouth is almost as
          suited to sorting things as an elephant's trunk. Hardware
          disease is basically unknown in equines. A horse could sort a
          Necco Wafer out of a stack of quarters and would stand in line
          to do so...  :-)</div>
