Overview
EN ISO 5395-3:2013/A1:2017 (Corrected version 2017-03) is a CEN-endorsed amendment to the international standard ISO 5395-3 covering safety requirements for combustion-engine-powered ride-on lawnmowers with a seated operator. This amendment updates and clarifies key safety provisions including Operator Presence Control (OPC), parking-brake actuation, Rollover Protective Structures (ROPS), pressurized hydraulic hoses, cutting‑means impact tests, grass‑catcher loading, and the test probe geometry. It is intended to support conformity with EU Machinery Directive 2006/42/EC when cited in the Official Journal of the EU.
Key Topics and Requirements
-
Operator Presence Control (OPC)
- Machines must have an OPC using well‑tried components or demonstrated equivalent design.
- OPC must require activation before traction and cutting drives start, require continuous activation during operation, and automatically stop drives if the operator leaves the seat.
- Restarting cutting‑means from a complete stop requires two separate, distinct actions (one must be OPC).
-
Parking brake
- Release of the parking brake must require either a minimum force (100 N), at least the actuating force, or two dissimilar actions to reduce accidental release.
-
ROPS (Rollover Protective Structure)
- ROPS are required for lawnmowers with mass ≥ 400 kg (working order definition provided).
- ROPS, if fitted, shall comply with ISO 21299 or an equivalent standard judged against it. Exceptions apply for certain seat/egress designs.
-
Pressurized hoses
- Hoses operating above 5 000 kPa and located within 1 000 mm of the operator must be shielded/positioned to prevent discharge onto the operator if ruptured.
- Similar protection applies to hoses 500–5 000 kPa that convey fluids >50 °C (ambient 20 °C ±5 °C) within 1 000 mm.
-
Cutting-means impact test
- Machines must withstand impact tests per ISO 5395‑1 Annex B. Test failures include target penetration, cutting‑means breakage, or detachment of cutting components.
-
Grass catcher testing
- Catchers are tested filled to max volumetric capacity using a material density of 150 kg/m³ ± 10 kg/m³, with provisions for high‑tip catchers and equivalent mass substitution.
-
Test probe
- Amendment includes the specified test probe geometry used for accessibility and guarding verification.
Applications and Who Uses It
- Manufacturers and designers of ride‑on lawnmowers use this standard to design safe products and demonstrate regulatory conformity.
- Test laboratories and certification bodies apply the impact, grass‑catcher and OPC functional tests during type approval and conformity assessment.
- Safety engineers, compliance officers, and procurement teams rely on the standard to specify protective features (ROPS, hose routing, parking‑brake design).
- Regulators reference the standard (via Annex ZA) when assessing conformity to the EU Machinery Directive.
