Abstract

An assembly includes a handheld work apparatus and a support. The support has a holder worn by an operator and a connector arrangement which is held at a first attachment on the holder and on a second attachment on the work apparatus. The connector arrangement is mounted on the second attachment so as to be pivotable about a pivot axis and supports the work apparatus in a rearward direction in relation to the operator and prevents a rearward movement of the work apparatus. The center of gravity of the work apparatus and the first attachment have a spacing (a) to one another measured in a horizontal and lateral direction in relation to the operator. The holder has, at the first attachment, a bracing device for supporting the tilting moment acting on the first attachment by the weight force (F) of the work apparatus because of the lateral spacing (a).
