Abstract
A trailer useful for carrying combine cutter heads - either corn or small grains. The trailer avoids interference with the combine when loading the head and also maintains a proper load balance after the head is loaded. It does so by using a trailer-wheel axle which is movable from a normal road position with the wheels well under the load to a rear position where the wheels are considerably behind the driving wheel of the combine as that machine drives up to the trailer so that the head can be detached and loaded.
