Abstract: According to the present invention a harvesting machine comprises a chassis with threshing and separating means and a power source mounted thereon and a grain tank pivotally mounted whereby it can be tipped to discharge grain contained therein rearwardly of the machine. The harvesting machine further also comprises a grain cleaning means mounted on the chassis and a conveyor means for loading grain into the grain tank. The conveyor means comprises a lower elevator extending from the grain cleaning means to the grain tank, an upper elevator mounted within the grain tank and aligned with the lower elevator when the grain tank is in the grain loading position, and disengageable coupling means disposed between the lower and upper elevators.

Abstract: This invention relates to mower conditioners of the type having at least two rotatable cutter units mounted side-by-side and each supporting at least one cutter blade to cut the standing crop by impact, as opposed to shearing. The mower-conditioner comprises a rotary crop conditioning and spreading apparatus extending rearwardly of the mower and having a pair of rotary units disposed rearwardly of each pair of cutter units, with each rotary unit being rotatable about a generally upright axis. One rotary unit of each pair of rotary units is located closer to the mower than the other rotary unit of the pair.

Abstract: An improved grain elevator is provided for a combine to transfer clean grain from the cleaning mechanism to a temporary, pivotally mounted, grain holding tank. The grain transfer elevator comprises a generally transversely and horizontally extending first auger disposed below the cleaning mechanism and connected to a second auger which extends upwardly in a transverse inclined direction through the bottom wall of the grain tank to a position at the top middle of the tank for discharging clean grain therein. The second auger includes separate parts releasably coupled together to thereby permit disengagement thereof for allowing the grain tank to be tipped for unloading.

Abstract: A rotary mower comprising at least one rotary cutter unit mounted on a framework, the framework having at least one forwardly extending lower support for rotatably supporting the cutter unit at its lower end, and a freely rotatable shield disposed proximate to the foremost edge of the or each support and underneath the or each cutter unit for shielding said foremost edge.

Abstract: The harvesting mechanism of the present invention uses a transversely extending threshing means and a rotary separating mechanism. The separating mechanism includes a transversely extending separating rotor having crop treating and crop conveying elements cooperating with a separating concave operable to receive crop material from the threshing means and separate grain from the crop material while the material is being conveyed spirally to one end for discharge.
