Road operation machinery - Safety - Part 4: Road service area maintenance machines - Requirements for grass and brush cutting machines

This European Standard applies to machines used for road service area maintenance 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. Directives and standards for the vehicular truck or tractor chassis aspect, termed 'carrier vehicle' in this standard, would be those relevant to that equipment.
For machinery which are a combination of a grass/brush-cutting attachment and a carrier-vehicle, this part of the standard applies to the grass or brush cutting attachment itself and with all health and safety requirements of the interaction and effects between attachment and the carrier vehicle when used together (e.g. stability, visibility).
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.
NOTE 1   Road regulations or Directive apply to vehicular truck and tractor.
NOTE 2   The use in public road traffic is governed by the national regulations.
This European Standard deals with all significant hazards identified through a risk assessment pertinent to road service area maintenance machines, when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4). This European Standard does not deal with significant hazards associated with EMC. This European Standard specifies 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.
This European Standard does not include requirements for the carrier vehicles (e.g. trucks, tractors, construction machines, industrial trucks). These are covered in directives related to the construction of vehicles.
This European Standard does not deal with:
—   walker-operated and hand-held machines;
—   machines for the maintenance of sports grounds;
—   machines for agriculture, horticulture and forestry;
—   pit and sewer cleaning vehicles/-machines;
—   grass and brush cutting machines with multiple cutting heads (see Annex A, Clause C.2, Figure C.20)
—   vertical axis grass and brush cutting machines except inter-post machinery (see Annex A, Clause C.2, Figure C.22)
—   horizontal axis grass and brush cutting machines with two rotors (see Annex A, Clause C.2, Figure C.23)
—   self-propelled remote controlled machinery for road service area maintenance, except the mowing head
—   self-propelled remote controlled machinery used for forestry application (see Annex A, Clause C.2, Figure C.21)
—   cleansing and ditch maintenance machines (see Annex A, Clause C.2, Figure C.24 and C.25)
A machine which is a combination of several parts with different uses should conform to all the standards referring to the corresponding parts of the machine.
This document, together with part 1, deals with all significant hazards for road service area maintenance machines – grass and brush cutting machines when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer associated with the whole life time of the machine (see Clause 4).
The requirements of this part are complementary to the common requirements formulated in prEN 17106 1:2017.
This document does not repeat the requirements from prEN 17106 1:2017, but adds or replaces the requirements for application for grass and brush cutting machines.
This European Standard does not deal with the risks associated with the operation of machines in potentially explosive atmospheres.
This standard applies to machines manufactured after the date of approval of this standard through CEN.

1 Scope

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.

EN 17106-1:2021, 4.1.3.1 and EN 17106-1:2021, 4.1.3.2 apply.
---------------------- Page: 14 ----------------------
SIST EN 17106-4:2021
EN 17106-4:2021 (E)
EN 17106-1:2021, 4.1.3.3 is replaced by the following requirement:

In case of lack of direct or indirect visibility on the cutting head of the machine from the operator's station, a

releasing device (see 3.6) shall be fitted on the equipment.
4.3 Precautions against hazards caused by moving parts excluding cutting head
EN 17106-1:2021, 4.1.5 applies with the following additions:

Rotating or oscillating machine parts on grass and/or brush cutting machinery shall be protected against

unintentional contact by means of guards which conform to EN 17106-1:2021, 4.1.5.

4.4 Interfaces
EN 17106-1:2021, 4.3.5 applies.
EN 17106-1:2021, 4.3.5.1, 1st sentence applies with the following addition:

For the mechanical interface complying with ISO 730:2009, ISO 11001-1:2016, ISO 11001-2:1993,

ISO 11001-3:2009 or ISO 11001-4:1994 shall also be used in conjunction with ISO 730:2009.

4.5 Unintended lowering of the equipment

a) The machine when used as intended shall prevent any unintended lowering of the mowing head and/or

boom.

NOTE 1 Unintended lowering is when a mowing head or boom runs back or descends because of an interruption or

an irregularity in the energy supply.
This requirement shall be achieved by the provision of:

— non-return valves or a corresponding function in the control valves of hydraulic or pneumatic lifting

devices, or;

— self-locking driving gear or an automatic drop-latch arrangement with a ratchet wheel for mechanical

winches, or;

— a control valve as a back-run safety mechanism, only if the adoption of non-return valves is technically

not possible.

b) Where persons have to stand under raised or tilted machines or components for maintenance purposes

thereof as part of the working procedure, unintended lowering shall be prevented. This can be achieved, for

example, by:
NOTE 2 The term “as part of working procedure” does not cover repair work.
— automatically engaging mechanical locks, or;

— externally unlocking non-return valves mounted directly on the lifting cylinder, or;

— mechanical safety mechanisms which are operated from outside of the danger zone.

---------------------- Page: 15 ----------------------
SIST EN 17106-4:2021
EN 17106-4:2021 (E)

c) Power-driven lifting devices shall not permit equipment to fall freely in an uncontrolled manner.

In hydraulic or pneumatic systems, this requirement is satisfied when the reverse flow is restricted e.g. by a

non-return valve, only if the adoption of non-return valves is technically not possible, an appropriately sized

orifice can be accepted.

d) Control valves and devices to protect lifting mechanisms against free-fall shall be so designed to ensure that

any variation of their setting is possible only with the aid of tools.

e) Demounting devices for demountable bodywork and components shall be designed and constructed to safely

support the equipment during the mounting or demounting process.
4.6 Special protection of the cutting head against objects being ejected

Machines shall be designed with protective measures (e.g. guards, chains, rubber plates) to prevent objects being

ejected uncontrollably by rotating tools towards the operator and into traffic areas where there is vehicular

and/or pedestrian traffic.

For grass and/or brush cutting machines and inter-post machinery, the testing method and verification means

given in Annex A shall be used.
4.7 Controls for machines using revolving/oscillating tools
EN 17106-1:2021, 4.1.4.5.3 applies with the following addition:

For hydraulic machines, it shall be possible to stop revolving or oscillating tools whilst the power source (i.e.

engine) remains running. It shall be possible to prevent the tools from being accidentally re-started.

The category of stop shall be Category '0' according to EN ISO 13850:2015, 4.1.4 (e.g. for blocking the fluid power

supply to the hydraulic/pneumatic machine actuators).

4.8 Special protection measures to prevent unintentional contact with revolving tools in the

operating area of grass-cutting machines
EN 17106-1:2021, 4.1.5 applies with the following addition:

Taking into account the necessity to be able to carry out grass-cutting operations in the direct vicinity of fixed

obstacles (e.g. delineators, traffic signs), the protective equipment shall be designed as follows.

a) Guard on grass -cutting machines in the direction of feeding and ejecting:

Guards in the direction of feeding and ejecting, e.g. deflector bar, shall be arranged as shown in Figure 5. The

spacing shall be measured from the path of rotation of the tools, where the grass-cutting machine is in the

operating position.

The removal or opening of guards shall only be possible using tools. For transportation these guards can be

removed or arranged on hinges.

This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13524:2003+A2:2014, EN 13021:2003+A1:2008 and
EN 13019:2001+A1:2008.

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association, and supports essential requirements of EU Directive(s).

For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this

document.

When a relevant specific part does not exist, part 1 can help to establish the requirements for the

machine, but will not by itself provide a means of conforming to the relevant essential health and safety

requirements of the Directive.

EN 17106 consists of the following parts under the general title road operation machinery - Safety:

— Part 1: General requirements
— Part 2: Specific requirements for road surface cleaning machines

— Part 3-1: Winter service machines - Specific requirements for snow clearing machines with rotating

Introduction
This document is a type C standard as stated in EN ISO 12100.

The machinery concerned and the extent to which hazards, hazardous situation and events are covered

are indicated in the scope of this document.

When provisions of this type C standard are different from those, which are stated in type A or B

standards, the provisions of this type C standard take precedence over the provisions of the other

standards, for machines that have been designed and built according to the provisions of this type C

standard.

1 Scope

This European Standard applies to machines used for road service area maintenance 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. Directives and standards for the vehicular truck or tractor chassis

aspect, termed 'carrier vehicle' in this standard, would be those relevant to that equipment.

For machinery which are a combination of a grass/brush-cutting attachment and a carrier-vehicle, this

part of the standard applies to the grass or brush cutting attachment itself and with all health and safety

requirements of the interaction and effects between attachment and the carrier vehicle when used

together (e.g. stability, visibility).

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.
NOTE 1 Road regulations or Directive apply to vehicular truck and tractor.
NOTE 2 The use in public road traffic is governed by the national regulations.

This European Standard deals with all significant hazards identified through a risk assessment

pertinent to road service area maintenance machines, when they are used as intended and under the

conditions foreseen by the manufacturer (see Clause 4). This European Standard does not deal with

significant hazards associated with EMC. This European Standard specifies 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.

This European Standard does not include requirements for the carrier vehicles (e.g. trucks, tractors,

construction machines, industrial trucks). These are covered in directives related to the construction of

vehicles.
This European Standard does not deal with:
— walker-operated and hand-held machines;
— machines for the maintenance of sports grounds;
— machines for agriculture, horticulture and forestry;
— pit and sewer cleaning vehicles/-machines;

— grass and brush cutting machines with multiple cutting heads (see Annex A, Clause C.2, Figure C.20)

— vertical axis grass and brush cutting machines except inter-post machinery (see Annex A,

Clause C.2, Figure C.22)

— horizontal axis grass and brush cutting machines with two rotors (see Annex A, Clause C.2,

Figure C.23)

— self-propelled remote controlled machinery for road service area maintenance, except the mowing

head

— self-propelled remote controlled machinery used for forestry application (see Annex A, Clause C.2,

Figure C.21)

— cleansing and ditch maintenance machines (see Annex A, Clause C.2, Figure C.24 and C.25)

A machine which is a combination of several parts with different uses should conform to all the

standards referring to the corresponding parts of the machine.

This document, together with part 1, deals with all significant hazards for road service area

maintenance machines – grass and brush cutting machines when they are used as intended and under

the conditions of misuse which are reasonably foreseeable by the manufacturer associated with the

whole life time of the machine (see Clause 4).

The requirements of this part are complementary to the common requirements formulated in

prEN 17106-1:2017.

This document does not repeat the requirements from prEN 17106-1:2017, but adds or replaces the

requirements for application for grass and brush cutting machines.

This European Standard does not deal with the risks associated with the operation of machines in

potentially explosive atmospheres.

This standard applies to machines manufactured after the date of approval of this standard through

CEN.
