A new ISO11839 - Machinery for Forestry-Thrown Object Guard (TOG) standard was published in February 2021. It is intended to provide reasonable protection for the operator of powered, rotating, cutting, or grinding elements and any matter thrown by an attachment. According to David Marotte, Engineering Manager, Custom Products of Litchfield, the updated standard establishes a test method for performance requirements of thrown object guarding to protect equipment operators. Charity Sanden, Manager of Business Development and Planning, Custom Products of Litchfield, says the company has special tools as well as cab design expertise to provide testing to help OEMs meet the new ISO standard.
