Harvesting equipment — Requirements for cutting elements — Part 2: Blades used on large rotary mowers
This document specifies requirements for blades used as cutting elements on large rotary mowers (as defined in ISO 4254-13) for shredding crop residue, grass and small brush by impact.
It specifies requirements for testing and marking of such blades.
This document is not applicable to blades used on:
— rotary disc mowers, rotary drum mowers, and flail mowers designed for forage crop harvesting as covered by ISO 4254‑12;
— arm-type large rotary mowers;
— pedestrian-controlled motor mowers;
— lawn mowers covered by the ISO 5395 series.
NOTE 1 The main purpose of this document is to set material characteristics. Blades on large rotary mowers are exposed to considerable centripetal forces and impacts with foreign objects. A bend test and Charpy impact test to check the brittleness and toughness of the material are therefore included in this document.
NOTE 2 This document does not specify dimensional requirements.

Frequently Asked Questions about ISO 5718-2:2023
When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.
Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
If you have an extensive portfolio of standards, we recommend using a professional standards management tool. With effects 2.0, you can manage your standards centrally and efficiently. You can optimise your procurement processes and benefit from an integrated information and subscription service. This ensures you are always up to date and never miss any relevant developments.
