In 2017, the Nebraska Tractor Test Lab evaluated the all-new Xerion 5000 and 4500 tractors by Claas, putting them head-to-head with competitors in the four-wheel-drive 450–500 hp class. At nearly 25 feet in length, Xerion 5000 and 4500 tractors are among the industry’s largest. Used primarily for heavy tillage, planting and seeding, the machines offer cutting-edge features like four-wheel steering, GPS capability and a rotating cab option. Highly sophisticated technology can also be found in their powerful six-cylinder mtu Series 1300 engines (OM 571), which meet Tier 4 Final emissions standards without the need for DPF aftertreatment.
At the Nebraska Tractor Test Lab, the new Xerion tractors broke records for fuel efficiency, pull-toweight ratio and low cab noise. The Xerion 4500 now holds the record as the most fuel-efficient tractor in its class. The Xerion 5000 and 4500 beat top competitors in engine lugging capacity, setting a record for low engine speed while providing maximum torque. In the ballasted portion of the test, the Xerion 4500 set a new 25-year pull-to-weight ratio record for 4WD tractors.
“When you’re in prime tillage season and running 10-12 hours a day, fuel efficiency really adds up. Cab noise on those long days is also a big concern,” says Sparenberg. The noise level recorded in the cab of the Xerion 4500 was a record-breaking low 68.5 decibels. The Xerion 5000 broke that record shortly afterwards with 67.0 decibels. As a comparison, that’s quieter than a Cadillac Escalade or Volkswagen Golf cruising at 65 mph (100 km/h).
“At Claas, we pride ourselves in offering premium products that focus on efficiency, productivity and comfort,” says Drew Fletcher, product manager – tractors, Claas of America. “Designing great products is our strength, but we also have some exceptional supply partners like mtu, that provide very efficient and productive components for our systems.”
