There is a need for a combine harvester which may enhance the detection precision of a gain culm sensor by reliably bringing grain culms into contact with the grain culm sensor. The combine harvester includes: a harvest frame 11 that receives grain culms cut by a reaping device; a rake-in auger 12 that is disposed within the harvest frame 11 so as to be rotatable about a rotary axis X1 extending in a right/left direction of the harvester body, and that conveys the grain culms inside the harvest frame 11 in a right/left direction of the harvester body and rakes in the grain culms toward the rear of the harvester body; and a feeder 13 that is communicatively connected to a rear wall of the harvest frame 11, and that conveys the grain culms raked in by the rake-in auger 12 toward the rear of the harvester body. A grain culm sensor 25 that detects the presence of the grain culms when coming in contact with the grain culms is disposed at a grain culm feed port 24a in the feeder 13.

An implement for moving plant material lying in a field including a frame, a plurality of rake wheels rotatably mounted on the frame, and a plurality of support wheels to support the frame in an elevated condition. The implement may have a plurality of configurations, and may include a merge configuration configured to merge windrows of plant material on the field surface by lateral displacement of the plant material on the field surface. The plurality of configurations may include a turn configuration configured to turn the plant material on the field surface with a degree of lateral movement of the plant material on the field surface. The plurality of configurations may include a fluff configuration configured to lift plant material off of the field surface without lateral displacement of the plant material on the field surface.

A modular gathering platform for grain harvesters is provided for coupling to the front of a grain harvester or processor which can gather plants previously prepared in one or more rows by at least one central belt conveyor with functional side by side coupling to other equal harvesting conveyor belts. The platform includes a transversal mounting structure having an internal opening, at least one central harvesting conveyor belt having front and rear extremities and two side couplings, additional harvesting conveyor belts coupled to the sides of the central belt, an anti-jamming roll and a rotating guiding roll. The central harvesting conveyor belt and additional side harvesting conveyor belts, the anti-jamming rolls, and the guiding roll are synchronized by an actuation assembly, and the guiding roll moves the harvested plants towards the exit. The platform advantageously allows for the gathering of a crop that has been prepared in rows.
