Abstract: A baler includes a chamber having a fixed size that receives crops and houses a formed bale. A tailgate is connected to a frame and is movable between a closed position, for cooperating with the frame to delimit the chamber, and an open position, for discharging the formed bale. A conveying assembly delimits the chamber for imparting a rotating movement to the crops contained in the chamber, and has a first portion provided in the frame and a second portion provided in the tailgate. An actuator includes a closing chamber and moves the tailgate from the open position to the closed position upon receiving an actuating fluid in the closing chamber.

Abstract: Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds in a direction centrifugally away from the rotor onto a stator including angularly adjustable stator surfaces around the axis. Thus the discarded seeds rebound back and forth between the rotor and the stator to provide a plurality of impacts. The destructor is mounted on a suitable drive shaft within the straw path and the chaff and weed seed material is carried from the rear end of the sieve to the destructor on the straw chopper by one or more fans driving the material through a transfer duct.
