John Deere's new 8R series launched in August is John Deere's replacement to the 8030 series, the most fuel-efficient row-crop tractors ever built, according to Nebraska Tractor Test Lab results. The series consists of six wheeled models ranging from 225 to 345 engine hp and three track models from 295 to 345 engine hp. The 345-hp 8345R is the most powerful row-crop tractor John Deere has ever built.

Deere says its new series offers more horsepower, good fuel economy, and a redesigned cab with 10% more space and more features. These include a premium sound package, redesigned control arm, easy-to-read display and an instructor seat that converts into a desk for a laptop or storage. Visibility is improved with the addition of more glass and repositioned cab supports.

The 8RT series track models are new from the ground up, featuring a new track suspension system for upgraded ride comfort and capabilities. For the first time, Deere is making its IVT available on its track tractors, offering it as standard on the 8345 RT and optional on all other models, enabling the operator to smoothly shift from 0 to 24 mph, or any speed in between, with a single lever. The track line also features John Deere's exclusive Air Cushion Suspension system, first made available on the company's larger 9030T series track tractors, to provide better vehicle traction as well as operator comfort.
