A cutting device (1) for use in cutting plant matter grown on a support structure and a method of use is disclosed. The support structure includes a plurality of support members (7) arranged into rows, and the cutting device includes a plurality of cutting elements (8) spaced apart from each other, characterised in that the cutting device is configured such that in use each cutting element can be inserted into a space between two support members and cut plant matter therefrom. Use of the invention for cutting kiwifruit vines and plant material is disclosed but could find use in alternate applications such as growing raspberries or other produce where growth for the next year&rsquos production is trained away from growth which provides a current years crop. In a particularly preferred embodiment, the growing structures with which the present invention is used includes strings. The strings (4) are positioned above the growing structure so that the new canes, being new growth from the kiwifruit vine, are able to grow up and along the strings. In a particularly preferred embodiment each cutting element is a pair of reciprocating sickle bars (8). The sickle bars move in opposite directions to assist the serrated edges (8) in cutting plant matter. The movement of the cutting elements is driven by motors, which are powered by a work vehicle (6) to which the cutting device is attached.
