Deere's evolution of its 8R series tractors is apparent with its launch of six new wheel and three new track models, all with Tier 4 Final engines ranging from 245 to 370 hp (182 to 276 kW). Beside the new engine and cab improvements, additional new options include LED lights, larger wheels/tires, and increased hydraulic capabilities.
Starting with the PowerTech PSS 9.0-L engines that meet regulations with impressive fluid economy, the new 8R/8RT tractors are engineered to provide what Deere calls uncompromised performance in the field. Both the wheel and track models have Deere's SCR system, which builds upon the Tier 4 Interim DOC/DPF exhaust filter solution, according to Jarrod McGinnis, Division Marketing Manager for Deere.
"We've increased the engine horsepower ratings of all the new 8R models and boosted the max hydraulic flow capacity by 41% to 85 gal/min. This 8R option allows customers to operate at reduced engine speed while handling larger implements such as planters that require high, constant flow rates," said McGinnis. "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.
These new 2014 models feature a new CommandARM and a Generation 4 CommandCenter. The completely redesigned CommandARM features improved ergonomics and integration of intuitive controls for the major tractor functions such as AutoTrac resume, throttle, transmission, SCVs, PTO, and hitch. The CommandARM comes with a 10-in 4600 CommandCenter display that swivels with the operator and can be equipped with GreenStar software such as AutoTrac. The 4600 CommandCenter Display has 800 x 600 dpi resolution, one USB port, four video inputs, and 32 GB of memory.
"Operators can customize the pages [on the display] to view the functions that are most important," said McGinnis. "It comes standard as a touch-screen display with video-streaming capabilities for remote cameras that could be attached to planters or other implements."
Other changes include a new CommandView III Cab with a 40° right-hand swivel operator's seat, which gives operators a more comfortable unrestricted view to the rear of the tractor and implements. Other features include the choice of optional ActiveSeat or Active Hydro-pneumatic Cab Suspension Plus, the cab suspension system that automatically adjusts ride quality based on terrain and operator preference. New 8Rs also come with an optional refrigerator to the left of the operator's seat.
"We've designed the new CommandView III Cab with laminated glass, a strategically placed insulation barrier, and an optional carpet floor mat to reduce noise and vibrations," said McGinnis. "Other enhancements include additional sunshades, window wipers, and improved key location, which are complemented by the swivel seat to make it a quieter and more comfortable work environment."
Track models feature configuration options capable of meeting a wide variety of operations and row spacings. These new track tractors are enhanced with the same engine, cab, control, and technology features highlighted with the wheel models. Both the 8Rs and 8RTs come with JDLink and John Deere Farmsight capabilities for improved visibility to operational and machine data via Wireless Data Transfer and Remote Display Access.
In September 2013, Deere announced that it will be investing approximately $40 million to create the capacity for manufacturing 8R tractors at the company's Montenegro, Brazil factory, primarily to enhance Deere's ability to serve customers in the important Brazilian market.
"Our customers in Brazil are investing in higher horsepower tractors in the range offered by the 8R model," said Mark von Pentz, President, Worldwide Agriculture & Turf Division. "Our decision to manufacture the 8R in Montenegro should allow the machine to be eligible for FINAME financing—the public program that targets investment in Brazil's economic development."
Deere's history in Brazil dates from 1979 when it first invested in a joint venture in the country. In 2008, Deere announced its decision to construct the Montenegro factory to increase its capacity for tractor production in the country.
Deere builds several models of tractors at the Montenegro facility but none in the high horsepower range offered by the 8R.
Deere currently manufactures 8R tractors in Waterloo, IA, and will continue to do so for markets around the world. Deere said reconfiguration of the Brazil factory will begin later this year, and it expects to be producing 8R models in Brazil by late fall 2015. Deere said the investment in Brazil will also increase the company's use of suppliers in the region.
