ABSTRACT:
A rear door control mechanism for a stack-forming implement having a compressor roof first raises the door vertically to unlatch it and then rotates the door about an elevated and horizontally transverse axis to permit stack unloading. The door control mechanism functions independently of the compression roof and other wagons' mechanical systems and assures positive door unlatching before the opening mechanism attempts to open the door.
