This document specifies requirements for blades used as cutting elements on rotary disc mowers and rotary drum mowers used for forage crop harvesting in agriculture only (as defined in ISO 4254-12) that are mounted, semi-mounted, trailed or self-propelled. It specifies requirements for testing and marking of such blades. This document is not applicable to blades used on: — flail mowers; — large rotary mowers covered by ISO 4254-13; — 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 rotary drum and rotary disc mowers are exposed to considerable centripetal forces and impacts with foreign objects. A bend test and 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.
Abstract
Overview
ISO 5718-1:2023 - "Harvesting equipment - Requirements for cutting elements - Part 1: Blades used on rotary disc mowers and rotary drum mowers" defines material, testing and marking requirements for cutting blades used in forage-crop harvesting (as defined in ISO 4254-12). The standard applies to blades on mounted, semi‑mounted, trailed or self‑propelled rotary disc and rotary drum mowers and is focused on ensuring blade toughness and durability under high centripetal forces and impacts with foreign objects.
Key topics and technical requirements
-
Scope and applicability
- Applies only to agricultural forage harvesting blades on rotary disc and drum mowers.
- Not applicable to flail mowers, large rotary mowers covered by ISO 4254-13, arm‑type large rotary mowers, pedestrian‑controlled motor mowers, or lawn mowers covered by ISO 5395.
-
Material requirements
- Blades shall be made of steel selected by the manufacturer.
- Minimum hardness: 38 HRC (Rockwell), tested in accordance with ISO 6508-1.
-
Bend test (brittleness check)
- Blades are progressively bent within a defined bending zone (inside radius R = 16 mm).
- Required bend angles depend on blade thickness:
- thickness
