MEJETAERSKER

An articulated self-propelled combine has front and rear units pivotally connected together for articulation about a vertical axis, the front and rear units being respectively supported on front and rear pairs of wheels. A harvesting header is carried by the front unit and feeds a fore and aft rotary separator, the combine engine and operator's station being mounted on the front unit on opposite sides of the separator. The separated grain is transferred across the axis of articulation to a cleaning mechanism on the rear unit, the cleaned grain being conveyed to a large grain tank disposed above the cleaning unit and spanning the width and length of the rear unit. The rear unit is also capable of oscillating relative to the front unit about a fore and aft axis, self-levelling means being provided for the rear wheels to maintain the cleaner is a generally level condition.
