EVS-EN 17106-4:2021

This document applies to grass and/or brush cutting machinery which are attached to or mounted on carrier vehicles (e.g. tractor, truck), or which are self-propelled machinery and which are defined in Clause 3.
For mobile machinery, which are a combination of a grass/brush-cutting attachment and a carrier-vehicle, this part of the standard addresses the relevant health and safety requirements of Annex I of the machinery directive which are inherent to the grass or brush cutting attachment itself and those resulting from the other risks which are only related to the combination of the grass/brush-cutting attachment with the carrier vehicle (e.g. interfaces between the attachment and the carrier-vehicle, stability, visibility). For machinery which are a combination of a grass/brush-cutting attachment and a carrier-vehicle, this part does not deal with the carrier vehicle itself which is covered by another European legislation.
For self-propelled machinery, this part only deals with health and safety requirements of the attachment itself and does not deal with the self-propelled machinery itself which are dealt with in EN 17106-1:2021.
The requirements of this part are complementary to the common requirements formulated in EN 17106-1:2021.
This document does not repeat the requirements from EN 17106-1:2021, but contains clauses/subclauses which supplement or modify the corresponding clauses/subclauses of part 1 to provide requirements for grass and/or brush cutting machinery.
When requirements of this document are different from those which are stated in EN 17106-1:2021, the requirements of this document take precedence over the requirements of EN 17106-1:2021 for machines that have been designed and built according to the provisions of this document.
NOTE 1 Road regulations or Directives apply to vehicular trucks and tractors, termed ‘carrier vehicles’ in this standard.
NOTE 2 The use in public road traffic is governed by the national regulations.
This document deals with all significant hazards identified through a risk assessment pertinent to grass and/or brush cutting machinery, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (transportation, assembly, dismantling and disabling, see Annex D).
This document specifies also the appropriate technical measures to eliminate or reduce risks arising from the significant hazards associated with machine operation, setting and adjustments, load discharge and routine maintenance.
