The American Farm Bureau is praising the EPA’s decision to revise Diesel Exhaust Fluid guidelines for heavy trucks and off-road equipment. President Zippy Duvall says the changes, including a grace period for refills and software updates, will prevent vehicles from losing power and help farmers stay on schedule during harvest and transport. Diesel Exhaust Fluid has been used in trucks and tractors since 2010 to reduce nitrous oxide emissions.
