The American Society of Agricultural and Biological Engineers (ASABE) has adopted the latest version of an ISO standard for mechanical connections of towed vehicles. It also has completed revisions to two parts of a five-part series on agricultural field equipment braking.
Connections for Towed Vehicles
The expanded scope of the revised ASABE/ISO 24347:2019, Agricultural vehicles—mechanical connections between towed and towing vehicles—dimensions of ball coupling device (80 mm), provides specifications for a ball coupling device that is either horizontal adjustable or close-position.
The adoption replaces the 2005 version of the standard and further harmonizes national and international standardization.
Revision to Braking Standards
Completed revisions of the ANSI/ASABE S648, Agricultural Field Equipment Braking, series of machinery standards, include part 4 and part 5.
ANSI/ASABE S648-4.1, Agricultural Field Equipment Braking—Part 4: Requirements for Towed Vehicles, includes clarifications regarding the definition of towed vehicle types.
ANSI/ASABE S648-5.1, Agricultural Field Equipment Braking—Part 5: Requirements for the Interface between Towing Vehicle and Towed Vehicles, includes additional clarifications and corrected interface-testing criteria.
ASABE members with standards access and those with site-license privileges can access complete information on revised standards at elibrary.asabe.org.
Farm Equipment Manufacturers Association members who are not members of ASABE are entitled to a no-cost flash card of all ASABE standards. It is a $695 value if ordered directly through ASABE.
