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.

ActiveSeat II

The John Deere Active Seat II utilizes an electrical control system to control the vertical seat top movement. The "active" control system minimizes vertical seat top acceleration by sensing vertical tractor inputs and actively positioning the seat top to cancel those inputs. This results in a significantly smoother ride for the operator.

The John Deere ActiveSeat II has many of the same features of the air suspension seat with the addition of a ride firmness switch. The ride firmness switch is located on the left-hand armrest and replaces the suspension shock-dampening seat attenuation lever on the front right-hand side of the seat controls.
  

The ride firmness switch has three positions: plus, minus, and mid position. The three positions provide three different levels of seat performance:

• The plus position provides the greatest degree of ride firmness. This position allows more of the tractor's inputs to be felt by the operator (slightly rougher ride).
• The minus position provides the least degree of ride firmness, allowing minimal tractor inputs to reach the operator, resulting in maximum seat performance.
• The mid position allows a balance between the plus (+) and minus (-) settings.

ActiveSeat II left armrest controls

The ActiveSeat II is also available as a heated and ventilated leather seat for increased comfort and easier cleaning. This is only available with the Ultimate Comfort and Convenience package. For tractor applications where operating speed is not limited by the implement, the ActiveSeat II can allow for faster field speeds and increased overall comfort and productivity.

The leather seat includes massaging capability to alleviate operator fatigue.

Right-hand seat swivel has been improved above current 8R Tractors to 25 degrees (versus 8 degrees) to the left and 40 degrees to the right in the Premium and Ultimate Comfort and Convenience packages.

NOTE: The John Deere ActiveSeat II is not available on track tractors.

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

8R Tractor equipped with ILS

Close-up view of ILS design

The John Deere ILS utilizes industry-leading technology to supply unsurpassed gains to end-user productivity. This innovative design incorporates proven suspension design with mechanical front-wheel drive (MFWD) axle components that use state-of-the-art technology specifically for heavy equipment usage. Operators do not have to worry about turning ILS on/off since the John Deere advanced electronic management system knows when to disengage ILS automatically.

The ILS system gets more power to the ground because the front tires maintain ground contact pressure. This improves field and transport ride plus increases ballasting flexibility and drastically decreases the tendency to power hop.

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.
