An axial flow combine harvester comprises a rotor having a separator section which can be adapted to suit different crops. Within the separator section staggered crop engaging elements are spaced from one another along a first helical crop flow path. The crop flow path can be modified to suit crops such as corn and sunflowers by attaching at least one separator blade to the rotor in place of or in addition to selected crop engaging elements of the rotor. The separator blade forms a continuous crop engaging surface defining a second helical crop flow path of greater pitch than the first path defined by the staggered strop engaging elements.

A combine harvester comprises a threshing and separating arrangement mounted to a main firm and including a generally cylindrical chamber having a generally longitudinal axis. Part of the chamber is constituted by a separating concave assembly comprising at least two separating concaves, the one located behind the other. The concaves are taken from a choice of less and more aggressive separating concaves. The chamber comprises mounting device operable to receive and hold each of the separating concaves. The front and/or the rear concaves can be removed and replaced.

A system and method for positively discharging crop residue from a combine for precisely and consistently delivering crop residue from the threshing and separating area of a combine to the combine's residue handling system or outwardly from the rear of the combine and onto the harvested field below as a windrow. The present invention can include, or operate in cooperation with, a discharge mechanism, such as a conventional discharge beater, which delivers at least some of the crop residue to a conveying mechanism of the system. The system also includes a guide mechanism including a door arrangement configurable in several alternative configurations for receiving and merging and regulating crop residue flow from the discharge mechanism and the conveying mechanism, and directing the merged flow to a desired processing mechanism, such as, but not limited to, a chaff spreader, a straw chopper and/or spreader, etc.

A system and method for detecting existence of a failed or broken shear bolt supporting all or a portion of a concave of a threshing system of an agricultural combine and utilizing information relating to rates of movement and absence of movement of a concave to determine the existence and non-existence of a failed or broken shear bolt supporting the concave. More particularly, the present system and method is operable to diagnose existence of a broken shear bolt from a rapid downward movement of the concave and non-movement of the concave during operation of a driver for repositioning the concave. Also, existence of a false broken concave condition can be diagnosed by movements of the concave responsive to operation of the driver.

The disclosure relates to a concave latch mechanism for an agricultural combine. The invention consists of concave surrounding a rotor. The concave has a concave pin and an adjust pin. The adjust pin is inserted into a support slot located in the frame. The concave pin is inserted into a handle also located on the frame. The handle has a lever which orients a curved cradle plate which supports the concave pin. When the lever is released, the cradle plate correctly orients the concave pin with the handle. The concave pin enters the cradle plate through an aperture. The aperture can have a sloped lead-in which assists in the positioning of the concave pin. The handle can also have an isolation mount between a portion of the handle and the frame. This isolation mount helps minimize vibrational noise from the rotor.

A disc mower incorporates a modular disc cutterbar. The drive mechanism for the mower utilizes a V-belt drive apparatus that requires proper tensioning which is accomplished through a spring tensioning mechanism that includes an indicator to visually determine when the proper tension has been applied. The indicator includes a bracket positioned adjacent the spring and has a length substantially equal to the length of the spring required for exerting the proper spring force for tensioning the drive belt.

A disc mower incorporates a modular disc cutterbar. The drive mechanism for the mower utilizes a V-belt drive apparatus that requires proper tensioning which is accomplished through a spring tensioning mechanism that includes an indicator to visually determine when the proper tension has been applied. A split guard is mounted to the distal end of the mower canopy to keep objects away from the end of the disc cutterbar. The guard presents a smooth contiguous surface to prevent debris and crop material from catching the guard. The flotation mechanism supporting the cutterbar from the mower frame must be disconnected before the mower is dismounted from the tractor three-point hitch. The support jack is tethered to the mower frame from the pin engaging the flotation mechanism, requiring the pin to be removed to install the support jack.

A sealing apparatus is provided for a pivot assembly on a disc mower incorporating a disc cutterbar to sever standing crop material by impact action. A first circular labyrinth seal has a T-shaped cross-section and fills a correspondingly-shaped groove between the pivot support arm and the gearbox housing. The combination of the T-shaped groove and corresponding labyrinth seal creates a labyrinth path for the entrance of dirt into the pivot assembly. A second circular face seal is constructed with a deformed inner diameter to create a lip that engages the face of the gearbox hubs. The deformed inner diameter lip of the face seal creates an inner cavity underneath the seal that can be filled with grease to provide a further deterrent to the entry of dirt into the pivot mechanism.
