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.

Methods and devices for automated adjustment of a digging implement during harvest of underground crops are described. Utilizing the devices, a digging implement, e.g., a blade, can be located and maintained at a desired depth as a harvester travels across a field. During use, the digging implement depth controls can be varied as the harvester travels within a single field under different operating conditions, e.g., different soil friability, consistency, etc., thereby preventing crop loss and improving crop yield.

A constructive arrangement applied to a grain harvesting machine reducing the sizes of the bulk carrier and the collecting set, bringing them to measurements which are compatible with the body of the machine, thus enabling transportation next to the machine, with no need to disassemble any parts, having hinges and support arms of the bucket and the support structure of the receiving device provided with hinging devices to reduce their lateral dimensions, those hinging devices being activated by hydraulic cylinders.
