During its recent Organization for Economic Cooperation and Development (OECD) test at the Nebraska Tractor Test lab in Lincoln, Neb., the John Deere 8335R tractor delivered 306.6 PTO hp in the rated-engine-speed PTO test. This sets a new record for PTO hp of a row crop tractor.
However, John Deere says the record will not be long-lasting. Its largest row crop model, the 8360R, is undergoing its official testing currently.
Tractor manufacturers are required to have all tractors above 40 hp sold in the state of Nebraska tested to verify advertised power ratings.
Located in Lincoln Neb., the Nebraska Tractor Test Laboratory
is the U.S facility for tractor tests. Twenty-nine countries adhere to the same testing codes of the OECD, and any OECD testing results are accepted by fellow testing locations.
