EN ISO 4254-20:2025 PDF

Overview

EN ISO 4254-20:2025 - "Agricultural machinery - Safety - Part 20: Grape, olives and coffee harvesters" (CEN adoption of ISO 4254-20:2025) specifies safety requirements and verification methods for the design and construction of trailed and self‑propelled grape, olive and coffee harvesters. Used together with ISO 4254-1:2013 and its amendment (AMD1:2021), this standard focuses on eliminating or reducing hazards for a single operator during normal operation and foreseeable misuse. Where provisions differ, EN ISO 4254-20:2025 takes precedence for machines built to its rules.

Key topics and technical requirements

The standard addresses machine safety across design, verification and user information. Major technical topics include:

• Operator’s station: ergonomic layout, seating and operating positions to reduce fatigue and improve control.
• Lighting and glare: requirements for visibility and lighting systems (visibility hazards otherwise are excluded).
• Extractors/blowers and cleaning systems: safe design and guarding for harvesting and cleaning components.
• Elements in direct contact with product: hygiene and mechanical safety for parts contacting grapes, olives or coffee.
• Stability: specific stability requirements for trailed and self‑propelled harvesters, and storage positions of picking units (separate requirements for grape/olive vs coffee harvesters).
• Power supply and remote control: requirements for failure modes, isolation of energy sources, remote control safety and presence detection.
• Brakes and parking brake verification: test methods and performance checks.
• Noise: assessment and limits are addressed (environmental hazards otherwise excluded).
• Batteries and other power sources: safety and isolation provisions.
• Audible alarms and horn: requirements for operator alerting.
• Guards and barriers strength: for moving parts and power transmission where relevant.
• Information for use: mandatory content for operator manuals, safety labels (including warnings about overhead power lines), and marking.

Practical applications and users

EN ISO 4254-20:2025 is essential for:

• Manufacturers and OEMs designing grape, olive and coffee harvesters to achieve safe machine design and market access in CEN member countries.
• Design and safety engineers implementing risk reduction measures and verification testing.
• Conformity assessors and notified bodies evaluating compliance with the Machinery Directive (see Annex ZA relationship to Directive 2006/42/EC).
• Maintenance teams and operators who rely on the operator’s manual and labelling for safe operation and servicing.
• Procurement and farm managers selecting compliant, safer harvesting equipment.

Related standards

• ISO 4254-1:2013 (and ISO 4254-1:2013/AMD1:2021) - general safety for agricultural machinery (used together with this Part 20).
• Machinery Directive 2006/42/EC - Annex ZA maps EN ISO 4254-20 clauses to essential requirements for conformity presumption.
