ISO 4254-20:2025

Overview

ISO 4254-20:2025 - "Agricultural machinery - Safety - Part 20: Grape, olives and coffee harvesters" is a Type‑C ISO standard that specifies safety requirements and verification for the design and construction of trailed and self‑propelled harvesters for grapes, olives and coffee. Meant to be used together with ISO 4254‑1:2013 and its amendment, this standard focuses on methods to eliminate or reduce hazards for the single operator during normal operation and foreseeable misuse. It clarifies manufacturer obligations for safety information (operator’s manuals, labels, marking) and sets precedence over ISO 4254‑1 where provisions differ for these specific machines.

Key topics and technical requirements

The standard addresses significant machine‑specific hazards and protective measures, including:

• Operator’s station ergonomics and layout (controls, steering location aspects)
• Lighting requirements for safe operation
• Extractor (blower) and cleaning provisions to reduce contamination and risk
• Components in direct contact with produce (grapes, olives, coffee) - hygiene and safety considerations
• Remote control systems and related safety requirements (with Annex A on remote control specifics)
• Power supply failure management and resilience for self‑propelled and trailed units
• Stability assessments for grape/olive harvesters and coffee harvesters, including storage positions for picking units
• Noise limits and warnings (noise is the only environmental hazard covered)
• Brakes, parking brake verification and audible/visual alarms (horns, audible travel alarms)
• Batteries and power sources, guards and barriers strength for moving parts related to power transmission
• Information for use: operator’s manual content, safety labels (including overhead power line warnings), and markings for lifting/tie‑down and stability

Notable exclusions: hazards from persons other than the operator, visibility issues except lighting, vibrations, and most steering aspects beyond ergonomics. Road traffic regulation specifics and machines manufactured before publication are outside scope.

Practical applications and who uses this standard

ISO 4254‑20:2025 is essential for:

• Machine manufacturers designing and certifying grape, olive and coffee harvesters
• Product designers and safety engineers implementing machine‑specific risk reduction
• Regulators, market surveillance, and safety auditors assessing conformity
• Agricultural contractors and service providers (maintenance, retrofits) seeking compliance guidance
• Purchasing/specification teams evaluating safe machinery for vineyards, olive groves and coffee plantations

Practical benefits include reduced operator injury risk, clearer manufacturer instructions, consistent safety labeling, and support for conformity assessment processes.
