Standards Development
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 ISO 5395.
There are a variety of cutting element types that can be used on large rotary mowers. This document will provide specific requirements for blades used on this type of equipment. The development of other parts of this standard will provide clear guidance on blade testing and performance specific to certain cutting element (blades in this case) types.
