Friend obtained a Gleaner K several months ago.We have been working on it as it had sat for quite a few years.Just getting around to working on the corn head that came with it,but that is not going well.It is a two row head which appears to be to narrow for the machine,and it is in really poor condition.What other corn heads will fit the K machine,and how available are they.He has several corn mazes and the corn is planted both directions.That is the questions about the width of the head.A three or a four head would be better for his needs.What should he expect to pay for one in decent condition
