All power-driven hazardous parts (e.g. drive belts), other than the cutting means, shall be so positioned or enclosed to provide adequate protection. The guarding of the cutting means is covered in 19.101, 19.102 and 19.103. Ground contacting parts (e.g. wheels) are considered not to be hazardous and are not required to be guarded.All openings and safety distances shall conform to 4.2.4.1 and 4.2.4.3 of ISO 13857:2019 unless otherwise specified in this document.Protective enclosures, covers, guards and the like shall have adequate mechanical strength for their intended purpose. They shall not be removable without the use of tools or shall withstand a force of 75 N in any direction.Opening the following guards does not require the use of a tool:a) interlocking guards which disable the protected moving parts; IEC 62841-4-3:2020 © IEC 2020 – 21 –b) automatically closing guards for grass discharge chutes.The use and adjustment of a guard shall not create other dangers, for example by reducing or obstructing the operator's view, by transferring heat, or causing other reasonably foreseeable hazards.Compliance is checked by inspection, by measurement, by functional test, by the tests of Clause 20 and by means of the test probe B of IEC 61032:1997 with a force not exceeding 5 N. Prior to the application of the test probe, any soft materials (elastomers), such as soft grip coverings, shall be removed. It shall not be possible to touch power-driven hazardous parts with this test probe.NOTE 101 In the United States of America, the following additional requirements apply.A protective shield of a lawnmower shall have sufficient strength and resilience to sustain forces associated with reasonably foreseeable misuse during operation.Compliance is checked by the following test.A 222 N static tensile force is to be uniformly distributed over not less than half the length of the shield. The force shall be applied for at least 10 s in the direction which produces the maximum stress on the shield. For the test, the shield shall be attached to the lawnmower in the manner in accordance with 8.14.2.The protective shield shall not permanently separate, crack or deform.
