A conditioner unit (6) for conditioning crop material comprises a rotor (17) having a shaft (18) that carries a plurality of conditioning elements, a drive mechanism for driving rotation of the rotor (17) about an axis, and a deflector element having a working surface (26) that surrounds at least part of the circumference of the rotor (17) to define a conditioning passage through which crop material is transported by rotation of the rotor (17). An adjusting mechanism (30) is provided for adjusting the position of the deflector element relative to the rotor (17), the adjusting mechanism (30) including an actuator (50), a sensor for sensing an operational condition of the conditioning unit (6) and a control system (56) that receives a sensor signal from the sensor and controls actuation of the actuator (50) in response to said sensor signal to provide a desired level of conditioning during operation of the conditioner unit (6).

A harvesting apparatus includes a crop conditioning element coupled to a frame, and a hood moveable relative to the crop conditioning element. An actuating system moveably connects the hood to the frame. The actuating system includes a driven lever arm rotatably attached to the frame and including a first lever connection and a second lever connection positioned opposite each other across a lever rotation axis. A first pivot assembly is rotatably attached to the frame and includes a first pivot connection coupled to the first lever connection of the driven lever arm, and a second pivot connection coupled to a first lift connection of the hood. A second pivot assembly is rotatably attached to the frame and includes a third pivot connection coupled to the second lever connection of the driven lever arm, and a fourth pivot connection coupled to a second lift connection of the hood.

A crop handling apparatus comprises a mobile chassis. The chassis is mounted on ground-engaging wheels. A tow-bar is provided at a front of the chassis for releasable attachment to a towing vehicle such as a tractor. A crop conditioning rotor is mounted on the chassis and has a plurality of outwardly projecting radial tines. Drive for the crop conditioning rotor can be by way of a drive transmission on the chassis which connects via a drive input with a PTO shaft on a tractor behind which the crop handling apparatus is drawn in use. A crop gathering conveyor is mounted on the chassis in front of the crop conditioning rotor. The crop gathering conveyor has a discharge end located in front of an inlet of the crop conditioning rotor to feed crop material to the inlet of the crop conditioning rotor in use.

A cryogenic processing system includes a cryogenic fluid source, and an auger, which includes an auger vessel containing at least one screw assembly. The screw assembly includes a flighting and a hollow shaft radially inward of the flighting. The shaft is in fluid communication with the cryogenic fluid source and includes one or more nozzles for dispensing cryogenic fluid within the auger vessel.
