Agricultural and forestry machinery - Pedestrian controlled motor mowers - Safety

This European Standard specifies safety requirements and their verification for design and construction of pedestrian controlled motor mowers with rotary or reciprocating cutting means used in agricultural, forestry and landscaping to cut and/or mulch grass or similar plants or scrub and woody vegetation.
For the purposes of this standard the following types of pedestrian controlled machines are considered to be motor mowers:
-   flail mowers;
-   grassland mowers;
-   scrub clearing machines;
-   sickle bar mowers.
This standard applies also to multipurpose machines when used for cutting or mulching grass or scrub.
Note   When they are used for other operations (e.g. soil working) other standards can apply.
This standard does not cover lawn mowers (see EN ISO 5395 1, EN ISO 5395 2), engine driven brush cutters and grass trimmers (see EN ISO 11806) or other lawn maintenance equipment.
This document deals with significant hazards, hazardous situations and events, as listed in Annex A, relevant to pedestrian controlled motor mowers when used as intended and under conditions of misuse foreseeable by the manufacturer during normal operation and service. Additionally, it specifies the type of information to be provided by the manufacturer on safe working practices.
Environmental aspects (except noise) have not been considered in this standard.
This document is not applicable to motor mowers manufactured before the date of its publication.

Ta evropski standard določa varnostne zahteve ter njihovo preverjanje glede zasnove in izdelave ročno upravljanih motornih kosilnic z vrtljivimi ali povratnimi rezili, ki se uporabljajo v kmetijstvu, gozdarstvu ter krajinskem načrtovanju za košnjo in/ali mulčenje trave ali podobnih rastlin ali grmičevja in gozdnega rastlinja. Za namene tega standarda so kot motorne kosilnice obravnavani naslednji ročno upravljani stroji:
– mulčerji;
– kosilnice za travišča;
– stroji za odstranjevanje grmičev;
– kosilci s srpom na drogu.
Ta standard se uporablja tudi za večnamenske stroje, kadar se uporabljajo za košnjo ali mulčenje trave ali grmičev. Ta standard ne zajema vrtnih kosilnic (glej standard EN 836), motornih žag za nego in motornih kos (glej standard EN ISO 11806) ali druge opreme za vzdrževanje trate.
Ta standard opisuje metode za odpravljanje ali zmanjšanje nevarnosti, ki izhajajo iz uporabe motornih kosilnic. Poleg tega določa vrsto informacij, ki jih mora predložiti proizvajalec v zvezi z varnimi delovnimi postopki.
Okoljski vidiki v tem standardu niso obravnavani.
Ta standard se uporablja predvsem za stroje, ki so bili izdelani po datumu objave tega standarda.

Overview

EN 12733:2018 is the European safety standard for pedestrian controlled motor mowers used in agricultural, forestry and landscaping operations. It specifies safety requirements and verification methods for machines with rotary or reciprocating cutting means - including flail mowers, grassland mowers, scrub clearing machines, and sickle bar mowers - and for multipurpose machines when used for cutting or mulching. The standard addresses significant hazards during normal use and foreseeable misuse and defines the information manufacturers must provide on safe working practices. Environmental aspects other than noise are excluded. The standard does not apply to lawn mowers (see EN ISO 5395 series), engine-driven brush cutters or grass trimmers (EN ISO 11806), or machines manufactured before its publication.

Key Topics and Requirements

The document covers technical safety requirements across machine design, construction and information for use. Major topics include:

• List of hazards and normative annexes identifying significant hazardous situations.
• Controls and operator interfaces: location, identification and reach zones for starting, stopping and movement controls.
• Engine starting/stopping: primary and secondary start measures and reliable stopping functions.
• Cutting means safety: requirements for blade guarding, stopping times, blade construction and protection against contact.
• Protection against thrown objects and structural integrity of casings for flail and scrub clearing machines.
• Drive, steering and brakes: service and parking brake requirements, steering forces and reverse traction drive considerations.
• Exhaust and hot surfaces: protection to prevent burns or exposure to exhaust gases.
• Electrical installations and protective measures.
• Noise and vibration: engineering test codes, measurement methods and requirements (noise is addressed; other environmental aspects are out of scope).
• Testing methods and annexes: noise test code, vibration measurement, foot probe and protective skirt tests, and verification procedures.
• Manufacturer information: instruction handbook content, markings and warnings required for safe use and maintenance.

Practical Applications and Who Uses It

EN 12733:2018 is primarily used by:

• Manufacturers and product designers to design and verify safe pedestrian controlled motor mowers and to prepare technical documentation.
• Test laboratories and conformity assessors to perform safety, noise and vibration tests described in the annexes.
• Safety engineers and procurement teams to specify safety features in purchase specifications and risk assessments.
• Training and maintenance personnel to develop operator instructions, warnings and safe-working procedures.

Adoption of this standard helps reduce operator injuries, improve machine safety design, and provide consistent safety information for agricultural and forestry machinery operatives.

Related Standards
