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.
