A cutting assembly includes: a rotor having extensions; a rotor floor disposed adjacent to the rotor and having knife slots formed therein, the rotor floor defining a cutting side and a shielded side on the opposite side of the rotor floor; movable knives that each extend through a respective knife slot into the cutting side to cooperate with the extensions in a cutting position and are disposed on the shielded side such that the knives do not cooperate with the extensions in a retracted position; and a knife guide including a pair of spaced apart guide surfaces coupled to the rotor floor on the shielded side and defining a gap therebetween. A respectively associated knife is at least partially disposed in the gap when in the retracted position. At least one of the guide surfaces defines a curved shape that corresponds to a cutting edge profile of the associated knife.

A continuous round baler forms a cylindrically-shaped bale by spiral, coiled layers created by a conical portion of a bale-forming chamber and protruded upwardly from a cylindrical portion of the bale-forming chamber. The bale is circumferentially supported by netting applied to the bale in the cylindrical portion. A rotary feed table receives crop from the field and feeds the crop into the conical portion. The bale forming process can be interrupted if an insufficient volume of crop is collected on the rotary feed table. The netting material is provided on short rolls to facilitate loading onto the machine. A cutoff mechanism is coupled to the growth of the bale from the cylindrical portion to sever the bale at a predetermined length with end surfaces that are perpendicular to the axis of the bale. A bale density mechanism supports the distal end of the bale as the bale protrudes upwardly.

An orbital plant material feed assembly includes a drum structure and hopper assembly. An external surface of the drum structure has a curved shape and includes a peripheral groove. A width of the peripheral groove varies along the external surface of the drum structure. The hopper assembly may define a compression space between the drum structure and a portion of the hopper assembly that covers a portion of the peripheral groove.

A hay baler (10) comprises a fore and aft hay bale forming zone, and a cut vegetation pick up and delivery arrangement for delivering cut vegetation to the hay bale forming zone. A compression plunger (19) of the hay baler (10) is movable in the fore and aft direction for compressing cut vegetation into a bale in the hay bale forming zone. A reservoir (23) retains a supply of non-toxic liquid surfactant or lubricant, and a pump means (25) is provided for pumping the non-toxic liquid surfactant or lubricant from the reservoir (23) at a supply pressure to one or more discharge outlets (32) in the hay baler (10). Thereby, inwardly facing surfaces in the fore and aft hay bale forming zone are at least partially coated with the non-toxic liquid surfactant or lubricant.

A self-adaptive control system comprises a feeding device, a rotary coder, a displacement sensor, a hydraulic regulation system and a controller, wherein, the input end of the controller is electrically connected with the rotary coder, the displacement sensor, a first oil pressure sensor and a second oil pressure sensor respectively, and the output end of the controller is electrically connected with a solenoid directional valve via an interlocking controller; the controller takes the bearing force of piston rods and the rotation speed and the rotation speed change rate of a feeding knife roller as input variables and takes the positions of the piston rods as an output variable, to establish a fuzzy control model of the feeding mouth opening of the feeding device, the extension and retraction of the piston rods in a left oil cylinder and a right oil cylinder under hydraulic driving are regulated actively by controlling a three-position four-way solenoid directional valve, and thereby self-adaptive control of the feeding mouth opening is achieved.

An apparatus for processing harvested crops, in particular a threshing and/or separating apparatus, comprising a rotor which is mounted rotatably about its longitudinal axis, a separating device with a separating device region which at least partially surrounds a lower circumferential region of the rotor, the circumferential region being arranged below the longitudinal axis in an operationally ready state of the apparatus, and is arranged radially spaced apart from the rotor. A passage region for the harvested crop is formed between the separating device regions and the lower circumferential region of the rotor, wherein the separating device region extends along the longitudinal axis, and comprises at least one control element. The control element is movable into the passage region and/or into an axial projection of the passage, in order to control the flow of harvested crop.

A rectangular baler including a baling chamber, an intake duct, a pick-up mechanism for picking up crop material and introducing it into the intake duct, and a stuffer mechanism to selectively execute a packer stroke to advance crop material partially along the intake duct and a stuffer stroke to transfer the crop material accumulated in the intake duct into the baling chamber. The stuffer mechanism includes a tine bar extending between two stuffer assemblies at each side of the baler. Each stuffer assembly includes a first stuffer arm connected at a first pivot point to a first crank arm of a first drive mechanism, a second stuffer arm connected at a second pivot point to a second crank arm of a second drive mechanism, and a coupling plate pivotally mounted around a stationary pivot point. The coupling plate couples the first stuffer arm with the second stuffer arm.
