Ultimate Visibility package

Visibility is one of the most important attributes of the cab. While lighting is a large portion of that, features like windshield wipers, mirrors, sunshades, and cameras are also important to overall visibility. For this reason, John Deere offers three visibility packages on 7 and 8 Family Tractors:

• Select 
• Premium
• Ultimate

Lighting

The lighting configurations are available to match various applications and ensure maximum around-the-clock productivity.

Light housings are large, allowing for optimum total lumens and available light. The Select Visibility package uses 65-W halogen bulbs, whereas the Premium and Ultimate Visibility packages use light-emitting diode (LED) lights. The Premium and Ultimate Visibility packages replace Select Visibility package’s halogen lights with LED lights. The only lights that are not LED are the low-beam driving lights; they remain halogen. This allows each LED light to work at a lower temperature and no one light works harder than any other. The uniformity in LED coverage allows only one type of light output surrounding the tractor.

The lighting pattern in the Ultimate Visibility package provides industry-leading performance in nighttime visibility. LED lights provide maximum brightness and a true color output for excellent field definition that is easy on the operator's eyes.

The LED lights provide 40 percent greater coverage width and 10 percent more light coverage in the rear. LED lighting packages use 45 percent less amps than standard halogen lights and have an increased life expectancy over HID lights which leads to lower costs of ownership over the life of the tractor.

The low- and high-beam driving/work lights are adjustable. Please refer to the electrical section in the Operator’s Manual for complete details on adjusting lights.

NOTE: Lighting packages may vary depending on region.

CommandARM™ console with CommandPRO control

The unique driving strategy is designed to deliver highest performance in combination with operator comfort making the daily work much easier and efficient.

Driving strategy

• Pedal and joystick mode are active at the same time
• ActiveZero keeps the output speed actively at 0 km/h (0 mph) until command for acceleration is given independent of load or engine speed
• Command top and zero speed simply by one push or pull
• Unique inching control
• Three easily adjustable travel set speeds
• Two engine set speeds
• Three acceleration response settings

Driving strategy

Hydraulic pump and filters

All 8 Family Tractors come standard with an 85-cc displacement integrated hydraulic pump. This pump provides 227.1 L/min (60 gpm) of hydraulic flow.

A dual-pump option, featuring 85-cc and 35-cc displacement hydraulic pumps, is available for all 8R and 8RX Tractors. The dual-pump system provides a hydraulic flow of 318 L/min (84 gpm), ideal for running at lower engine speeds.

Operating the tractor at reduced engine rpm contributes to a quieter cab, reduced fuel usage, and maintains the vacuum while turning and raising the planter on end rows. At 1500 engine rpm with a 318-L/min (84-gpm) system, there will be an available flow of 229 L/min (61 gpm). This is an improvement over an available 162-L/min (43-gpm) flow when operating with a 227-L/min (60-gpm) system at 1500 engine rpm.

The maximum flow through one selective control valve (SCV) with a standard coupler is 132 L/min (35 gpm). A 19.1-mm (3/4-in.) high-flow coupler allows for a maximum flow rate out of one SCV of 153 L/min (40.5 gpm).

The hydraulic system is a closed-center, power-on-demand system using a load-sensing pressure-flow compensated axial piston pump with full-flow charge and flow prioritization for steering and brakes.

The pump outlet pressure available on demand can range from 3000 kPa (435 psi) for track models and 4000 kPa (580 psi) for wheel models at low standby to 20,400 kPa (2958 psi) at high standby.

Maximizing uptime for John Deere customers through the use of connectivity and technology

John Deere Connected Support is a proactive service approach that utilizes the telematics machine connection to leverage a suite of remote support tools available to improve service efficiency and reduce machine downtime on all 7, 8, and 9 Family Tractors.

• Proactive services that drive more uptime
• In-the-moment services to ensure quality job performance
• Leveraging technology to be more effective and efficient

You know that when you’re in the field the unexpected can happen. When it does, you need a quick resolution. That’s why John Deere equipment is prepared with technology that senses potential issues and can alert you promptly—in the cab or anywhere you are. Better yet, your dealer can receive alerts and connect to your equipment. You know your dealer is always ready to keep you farming – and farming better. Starting with model year 2020, your John Deere tractors will come with a 5-year JDLink™ subscription from the factory that makes this connection possible.

John Deere Connected Support tools

Stop fearing the unexpected and start planning for it with the following John Deere Connected Support tools.

Monitor machines on the go

Connectivity provides data that drives better decisions

Customer needs and their success is John Deere’s focus. As functionality becomes more accepted and even expected, that functionality moves from being optional to being included with the machine. In model year 2019, AutoTrac™ guidance and documentation was included on machines equipped with a 4600 CommandCenter™ Display. Five years of JDLink is also included with the purchase of all model year 2020 machines equipped with a 4G LTE Modular Telematics Gateway (MTG). The functionality of JDLink on these machines includes everything that was previously included with JDLink Access + Remote Display Access (RDA) and JDLink Connect subscriptions. This added connectivity enables customers to more easily realize the value of a connected machine.

• Easily transfer data and collaborate with trusted advisors to plan your field work quickly. You or your employees can spend more time in the field working rather than sitting on a headland setting up the technology. With a connection between John Deere Operations Center and your machines, changes to field plans occur as needed. Those changes may include changes in varieties, application rates, or machines.
• Better enable data-driven decisions. By using the insights gathered from machines along with the tools in Operations Center (e.g., Field Analyzer, Field Analyzer Beta, and Machine Analyzer) you can understand how your fields are performing and what field plans had an impact. John Deere Operations Center gives you access to more than 100 connected software tools, so you have the ultimate choice of popular industry tools. And, if you don't want to analyze the data yourself, you can share the data with those that help you make decisions to provide the insights you need.
• Report work completed accurately and timely for compliance and billing purposes.
• Increase machine uptime with Connected Support. Your local John Deere dealer can provide remote monitoring services and diagnostics to help keep your machines up and running, reduce your maintenance expenses through early detection of problems, and provide over-the-air software updates for displays, receivers, and controllers.
• Get quick in-field support with RDA. You can monitor your machines from your office computer or a mobile device on the go.
• Remotely manage machines and employees to give you insights into how they are performing. If machines are being underutilized or field operations are not being properly conducted, you can put plans in place to improve productivity.
• Quickly make changes to improve your harvesting operations by remotely viewing and adjusting combine settings.
