John Jams of Redfield, S.D., has invented a feedbunk to last a lifetime. It will not crack, bend or rust because it’s made of rubber: a 4-foot-wide piece of belt that came from an expired coal or gravel conveyer. The belt can be cut to the necessary length depending on the number of cattle. Mr. Jams used brackets built from channel iron to make his rubber bunk. Lengths of chain on each make for easy handling. When the bunk needs to be cleaned, he flips it with a tractor loader; rough handling is not a problem. If it freezes to the ground, pulling on it sideways will quickly break it free.
