John Deere adds three dynamic and efficient track models

  • 20-Dec-2011 10:23 EST

Deere's 9RTs are equipped with the Durabuilt 5500 rubber track that is manufactured with four-ply layers for tough debris and resistance to high side loads. To increase durability, Deere enhanced the internal construction with a heavy-duty main cable and optimized it for puncture resistance.

According to Deere, the highlight of its new 9R/9RT scraper Special Series tractors are the three track models—the 9460RT, 9510RT, and 9560RT.

"Our special track models will help contractors navigate the harshest terrains on their job site,” said Mark Oliver, Product Marketing Manager for scraper systems, John Deere Construction & Forestry.

Rounding out the lineup are three wheeled models (9460R, 9510R, 9560R). The full line is equipped with a fuel-efficient, high-torque Tier 4 Interim 13.5L PowerTech PSX engine featuring 460 to 560 hp (338 to 412 kW).

The 9460RT, 9510RT, and 9560RT are equipped with the Durabuilt 5500 rubber track in a 30-in width. These tracks are manufactured with four-ply layers and are designed for tough debris and resistance to high side loads. To increase durability, Deere enhanced the internal construction with a heavy-duty main cable and optimized it for puncture resistance.

“Operators asked us for a tracked tractor to give them a comfortable and dynamic piece of equipment suitable for use on soft, low friction, and uneven ground,” Oliver said.

Answering the customers’ requests, all 9RTs are equipped with an AirCushion suspension system. This suspension isolates the entire front chassis when operating on harsh, uneven terrain. The entire system is fully automatic and requires no operator adjustment or special care. In addition, this system allows the tractor to travel much faster over rough terrain found in everyday operations, while increasing operator comfort.

Fitted with the all-new CommandView II Cab, the 9R/9T Series Tractors provide operators with what Deere says is an industry-leading spacious and comfortable cab. The new cab design and layout "takes the mobile office environment to a new level" with easy-to-use fingertip controls and enhanced visibility, convenience, and productivity. Improvements to the cab include a 10% increase in overall cab volume, 7% more glass area, and four times more storage area over the previous CommandView cab.

In addition to the new cab design, Deere incorporated other comfort features to ensure a productive and enjoyable ride. The right-hand console from previous models was removed to improve visibility and provide more space. In its place, Deere added a right-hand convenience area. This area includes: two cup holders, an ISO connector, power outlets, an MP3 jack (premium radio option required), and storage for cell phones, MP3 players, etc.

The functions and features formerly located on the right-hand console were relocated to the redesigned CommandARM, including a new 7-in color CommandCenter display. The CommandArm provides fingertip controls of key tractor functions, including throttle, transmission speed and direction, and selective control valves. Additional adjustments and configuration settings are made on the optional touch-screen capable GreenStar CommandCenter display.

In an effort to lower daily operating costs, Deere incorporated the Powershift transmission with Efficiency Manager as base equipment on all 9R/9RTs. This transmission allows the tractor to operate at an optimal performance level while minimizing fuel consumption. With a thumb wheel located on the transmission lever, the Efficiency Manager gives pinpoint ground-speed control by allowing the operator to set speeds for transport or when the operator is not in the cut loading dirt.

Efficiency Manager also allows maximum efficiency and productivity from the tractor through continuous communication between the engine and transmission. The program can make appropriate adjustments based on inputs received from the tractor and matches engine and transmission performance to ground speed, providing a fuel-efficient tractor.

For those fleet managers, owners, or operators looking to get the most out of their equipment, the JDLink system continuously collects and transmits machine data for machine management via mobile phone technology. The system enables the preventive maintenance and remote diagnostics of tractors, as well as the tracking of machines working on multiple job sites.

The 9R/9RTs incorporate feedback directly from Deere customers. To start, Deere included a new common hydraulic/transmission/axle oil reservoir that provides the operator many benefits, including improved oil-level management and a common oil reservoir that improves ease of operation by decreasing the number of checkpoints. Additionally, the oil reservoir allows the operator to easily maintain the proper oil level for all conditions. For improved serviceability, the 9R wheel tractor now has two hydraulic oil filters, instead of one. This enhancement increases the service interval from 750 to 1500 h.

Other improved features on the scraper tractors include enhanced fender coverage; upgrades to the frame, chassis, and axles; and a standard tow cable. The increased tire fender coverage helps the operator spend less time cleaning dirt and mud off windows and more time in the cab.

The foundation of the 9R Scraper Special Series is a three-section frame with components specifically designed for the harsh demands of the job site. Axle flats integrated on 4.72-in (120-mm) diameter axles offer improved wheel attachment and reduced maintenance. The axle lubrication system features pressurized cooled and filtered oil for greater axle component reliability and service life. In addition, the tow cable is now included as base equipment and is no longer a field-install-only kit.
