B5 Biodiesel Fuels Approved for Kubota Diesel Products

Kubota Tractor Corp. (KTC) recently announced a global decision to approve
the use of B5 biodiesel fuels in specified Kubota diesel-powered products.
Biodiesel fuels, most often offered in a blended-petroleum format, are derived
from vegetable oils such as soybean and are offered in the United States as an
alternative source for energy. The approved blends of biodiesel fuel for use in
Kubota diesel-powered products range up to a B5 blend that consists of 5 percent
biodiesel and 95 percent petroleum diesel.

“Kubota is committed to environmentally sound practices and the support of
renewable, agriculturally based products used in fuels — as we continually work
at increasing energy efficiencies within our industry,” said Tetsuji “Mike”
Tomita, president of Kubota Tractor Corp. “Kubota believes strongly in the
efficiency and high performance of the diesel engine and approves the use of B5
biodiesel fuels.”

Kubota has tested and approved the use of American B5 biodiesel fuel as a
blend component that meets the minimum requirements provided by the American
Society of Testing and Materials, Standard ASTM D6751 specifications. The
petroleum diesel fuel base must meet the ASTM D975 specifications. To ensure
quality, biodiesel fuels or blended fuel should be purchased from a BQ-9000
accredited producer.

Kubota recommends compliance with appropriate handling, storage, operating
and maintenance of diesel and biodiesel fuels to ensure quality and safe
handling.
