ASABE Revises Safety Standards for PTO Operations

The American Society of Agricultural and Biological Engineers (ASABE) has completed a revision to one of its most widely used standards.

The revision, ANSI/ASAE S318.19, Safety for Agricultural Field Equipment, changed requirements to the operator presence control when the power take-off (PTO) is engaged. An option was added to allow the use of a loud audible alarm in the area of the PTO if the PTO is operating without an operator in the operator’s station. Additionally, if the PTO is to be run intermittently for an extended period without an operator in the operator’s station, the revision allows the PTO alarm to be overridden until the tractor is stopped. Previously the alarm had to be overridden each time the PTO was restarted.

ASABE members with standards access and those with site-license privileges can access the full-text via electronic download on the ASABE online Technical Library at elibrary.asabe.org/. Others can obtain a download for a fee directly from the library or by contacting ASABE headquarters at OrderStandard@asabe.org.
