Abstract: The present invention refers to vertical roller devices to assist the supply of stems to sugar cane harvester, which are installed on the front side (A) of the harvester, fastened to the row dividers and which work in pairs, with elements on the right and on the left, which can consist of one or more pairs. The devices are designed to continuously propel and to guide the sugar cane stems to the inside of the harvester. The devices with vertical rollers (6) are formed by hydraulic motors (6a), finned cylinders (6b), upper fixing support members (6c) and lower fixing support members (6d). In the case of a single row, the devices are installed in the harvesters in accordance with to (B) and, in the case of two or more rows, in accordance with (C) on the inner faces (2) of the row dividers.

Abstract: A cutting system for a harvester, the cutting system including a knockdown roller, at least two row dividers, at least two base cutting elements, and at least two inner base cutting discs. Each of the at least two base cutting elements is disposed in the structure of a respective one of the at least two row dividers. Each of the at least two inner base cutting discs is disposed behind the knockdown roller. The cutting system further includes two arms and a lifter roller. Each of the two base cutting elements is connected to a respective one of the two row dividers by a respective one of the two arms. Each of the two base cutting elements is positioned entirely forward of the knockdown roller and the lifter roller.

Abstract: This invention relates to harvesting machines and more in particular, to harvesting machines capable of harvesting more than one crop row. In this scenario, this invention has the objective of providing a system for harvesting machines that make it possible to cut more than one crop row simultaneously. To this end, a cutting system for harvesting machines is proposed, comprised by at least two row dividers (6) and by at least two cutting elements (16), each of the at least two cutting elements (16) are positioned in the structure of each of the at least two crop rows (6). This invention further provides for a harvesting machine comprises said system.
