A harvester lifts plant material and usable product off the ground using a header to create one or more distinct ribbons of material which are each fed axially into the front of rotating foraminous drums carrying stripper springs and within which a rotor with threshing springs and a screw conveyor on its outer surface is cooperatively mounted. The usable product thus separated from the plant material exits the foraminous drums to be collected and conveyed to the cleaning portion of the harvester. The product and foreign material are mechanically sized using a series of rollers and an air stream separates the product for subsequent trimming of stems therefrom. The product is then deposited on a sizing conveyor further separation and weighing.

A self-propelled harvester such as a combine harvester including a frame having a main frame assembly and a pair of secondary frame members attached thereto. The main frame assembly supports crop processing apparatus. A feederhouse and a tangential-flow crop impelling rotor are journaled between the secondary frame members. The secondary frame members are conveniently removable from the main frame assembly for accessing the processing apparatus from a front end of the harvester.

A chopper for receiving the straw and/or chaff from a combine harvester includes a housing with a chopping rotor to transport the materials though a discharge opening onto a tailboard construction with downwardly facing guide surface and fins for spreading of the crop materials. A rotary spreader has a plurality of fan members with blades rotatable for discharge to a respective side of the rotary spreader. An arrangement is operable so that in a first mode the crop material is spread wholly by the tailboard and in a second mode the crop material is spread at least mainly by the rotary spreader. In the second mode the tailboard remains position above the rotary spreader which is therefore located underneath a guide surface with fins of the guide surface facing downwardly adjacent the blades. The movement to the second ode is provided by the rotary spreader being moved forwardly and downwardly.

A cutting longitudinal swaths grain harvesting and baling combine, includes a grain cutting and conveying system, a threshing and separation system, a grain cleaning apparatus, a grain collection and holding system, a straw compression and baling apparatus, a chassis travelling system, and a driving system; when the combine is harvesting grain in fields, the stalks are cut and conveyed to the threshing and separation system by the grain cutting and conveying system; the threshed and separated straw is compressed and baled by the straw compression and baling apparatus; the threshed and separated grain is cleaned by the grain cleaning apparatus; and the cleaned grain is conveyed by the grain collection and holding system to a grain storage bin. The combine can achieve harvesting of grain such as rice and wheat as well as compression and baling of threshed straw, having advantages of high working efficiency, stable performance, a simple process, and being time and labor saving.

A helical auger flight has an inner edge, an outer edge, an inner face, an outer face, and a leading extremity that includes a prominence and a leading edge that extends from the outer edge to the prominence. The prominence extends outward from the leading edge of the leading extremity to an outer end having an upturned jut. A wear plate is releasably connected to the inner face of the helical auger flight. The wear plate extends from the outer edge of the helical auger flight to the prominence. A front extremity of the wear plate extends forwardly of the leading edge of the helical auger flight so as to be in a shielding relationship with respect to the leading edge of the helical auger flight, and a nose of the front extremity of the wear plated is seated in direct contact against a contact surface of the jut.
