Abstract: A combine harvester stone trap having its upwardly facing inlet generally in the proximity of the transition between the discharge end of the crop elevator and the forward end of the combine threshing concave. The stone trap includes a front wall in the form of a door which can be opened into a retracted position for emptying the stone trap and a rear wall which, in an operative position, effectively closes the gap between the forward end of the threshing concave and the forward end of the combine grain pan located below the concave in a conventional manner. The rear wall is movable into an inoperative position providing access to the gap between the forward ends of the threshing concave and the grain pan.

Abstract: A combine harvester having a threshing and separating mechanism and a grain cleaning mechanism disposed beneath the threshing and separating mechanism and including a grain pan fitted with a movable divider apparatus and operable to receive grain from the threshing and separating mechanism, sieve mechanism operable to receive grain from the grain pan, and a fan operable to blow air through the sieve mechanism, is disclosed wherein an inclination sensing mechanism for sensing the lateral inclination of the combine harvester is operatively associated with an actuator operatively coupled to the grain pan divider apparatus for positionally adjusting the grain pan divider apparatus in response to the output of the inclination sensing mechanism to compensate for any given lateral inclination of the harvester.

Abstract: A combine harvester is disclosed wherein the operative components thereof are built according to a modular concept. The combine harvester includes a threshing module, a separating module and a cleaning module, all of which are supported by a frame and operably interconnected. Each respective module is interchangeable with a like module having a different configuration.

Abstract: A harvesting machine comprising a threshing mechanism, a transverse rotary separator mechanism having discharge outlets adjacent its opposite ends, and discharge channels in register with the discharge outlets leading to a common strawhood. The separator mechanism is arranged spirally to convey crop material received from the threshing mechanism toward each of its ends while submitting the crop material to a separating action and to forcefully eject crop material through said discharge outlets and through said discharge channels in the direction of the common strawhood. A crop material chopper device is associated with each discharge channel and is disposed out of the normal path of the crop materials through the respective discharge channel. A deflector device associated with each chopper device is adjustable between a position retracted from said normal path of the crop material and a further position across said normal path.

Abstract: A harvesting machine comprising a transversely extending threshing mechanism having a threshing cylinder cooperable with a threshing concave for threshing a layer of crop material fed therebetween and a separating mechanism having a first and a second separating component, operable to submit the layer of crop material received from the threshing mechanism to a first and a second separating action. The first component comprises a separator cylinder cooperable with a separator concave and has a plurality of beater means transversely spaced apart on the width thereof. The beater means are arranged to impact on sections of the layer of crop material received from the threshing mechanism, thus submitting said material to said first separating action and conveying it to the second component. The second component comprises at least one separator rotor cooperable with a separator housing including a separator concave.

Abstract: A combine harvester with a threshing, separating and cleaning device, the cleaning device comprising a grain pan (6), at least one cleaning sieve (7, 8) and a cleaning fan (9) operatively positioned relative to each other and pivotable in unison about a generally fore-and-aft extending axis (53) so that, when the combine harvester is transversely inclined relative to the horizontal, the cleaning device may be leveled to a transverse generally horizontal position.

Abstract: A havesting machine comprising a separating mechanism having a separating rotor cooperable with a separator housing including a separator concave and arranged spirally to convey crop material to at least one end thereof while submitting said crop material to a separating action and cleaning means disposed below the separating mechanism for cleaning separated grain. Deflector means are provided which together with the separator concave define an open ended cavity having its open end facing to the cleaning means for leading grain separated through said separator concave to said cleaning means. An air inlet is provided in the deflector means defining the cavity at the upper portion of said cavity.

Abstract: A combine harvester includes an auger, a rethresher rotor and an impeller for transferring crop material from the auger to the rethresher. A shaft, rotatably mounted in the harvester, carries the auger, the impeller and the rotor.

Abstract: A harvesting machine comprising a transversely extending threshing mechanism having a threshing cylinder cooperable with a threshing concave for threshing a layer of crop material fed therebetween and a separating mechanism having a separator rotor cooperable with a separator housing including a separator concave and disposed parallel to the threshing mechanism and being arranged spirally to convey portions of the layer of crop material received from the threshing mechanism towards each of its ends while submitting the crop material to a separating action. A rotary member with a plurality of beater means transversely spaced apart on the width thereof, is disposed between the threshing mechanism and the separating mechanism for orienting crop material in the layer of crop material received from the threshing mechanism generally lengthwise in the direction of movement of the layer.

Abstract: A combine harvester includes a conveyor attached tangentially to a rethresher rotor. An auger extends from the rethresher to a grain pan. A rotatable shaft carries the auger and also carries an impeller. The auger has a first diameter adjacent the rethresher rotor and has a second, larger diameter adjacent the grain pan.

Abstract: A rotor for an axial flow combine which is adapted to coact with conventional grate means in said combine, said rotor having on the forward end thereof interrupted infeed flight means which are spiral segments spaced both axially and circumferentially from each other, and certain of the leading ends of said flight segments in the direction of rotation of the rotor extending radially a limited distance beyond the outer edges of said segments to provide aggressive engagement of said segments with crop material being delivered to said flight from conventional elevator mechanism and the like normally employed in combines.

Abstract: In a combine harvesting machine comprising a plurality of interconnected sub-assemblies, there is provided the apparatus and the method for utilizing an entirely separate, self-contained, and self-supporting straw walker sub-assembly that may be mounted to a mobile chassis during the production line assembly.
