The evolution of John Deere’s popular workhorse 8R Series Tractors will continue in 2014 with the introduction of six new wheel and three new track models.

All models will feature Final Tier 4 engines ranging in horsepower from 245 to 370.

These new models will integrate the latest technology to provide the utmost in power, comfort and performance for row-crop tractors in this class.

The new 8R/8RT Series Tractors feature a new CommandARM and a Generation 4 CommandCenter with 10-inch display, along with other cab improvements that enhance operator comfort and convenience.

Additional new options include LED lights, larger wheels/tires, and increased hydraulic capabilities.

Starting with the PowerTech PSS 9.0L SCR engines that meet Final Tier 4 emissions regulations with outstanding fluid economy, the new 8R/8RT Tractors are engineered to provide uncompromised performance in the field.

Both the wheel and track models have John Deere’s highly efficient selective catalytic reduction system, which builds upon the Interim Tier 4 DOC/DPF exhaust filter solution, says Jarrod McGinnis, division marketing manager for John Deere.

 “We’ve increased the engine horsepower ratings of all the new 8R models and boosted the max hydraulic flow capacity by 41 percent to 85 gallons per minute. This 8R option allows customers to operate at reduced engine speed while handling larger implements such as planters that require high, constant flow rates,” McGinnis says.

“And all tractors have the opportunity to be equipped with Intelligent Power Management, which increases power and torque to maximize performance. In fact, with Intelligent Power Management on the 8370R Tractor, customers can boost engine performance to 405 horsepower.”

The new 8R Tractors are available with either 16-speed Power Shift or an IVT transmission. The 8345R, 8370R and all three track models feature the IVT as standard equipment. In addition, Group 49 rear tires are available on all wheel models which improves traction, increases load-carrying capacity, and reduces soil compaction in the field because of a larger tire footprint.
