The 7R, 8R, and 8RT Series Tractors feature two lighting package options:
The cab lighting pattern provides 330 degrees of coverage while the hood lighting provides the remaining 30 degrees for completely programmable 360-degree, stadium-style lighting. This ensures there are no dead zones or lighting adjustments needed. The lighting configurations are available to match various applications and ensure maximum around-the-clock productivity.
Bulb housings are large, allowing for optimum total lumens and available light. The standard lighting packages use 65-W halogen bulbs, whereas the premium lighting package uses light-emitting diode (LED) lights. In the premium lighting package, these tractors take advantage of the high-performing and efficient LED technology.
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.
Six front grill-mounted lights:
10 cab roof-mounted lights:
Plus these lights:
Eight front grill-mounted lights:
12 cab roof-mounted lights:
The premium lighting package replaces all previous halogen and HID 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 premium package provides industry-leading performance in nighttime visibility. LED bulbs 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.
NOTE: Lighting packages may vary depending on region.
Operators can quickly select a lighting mode on the steering console:
The CommandCenter display allows operators to customize light settings. Operators can select only the lights they need or want for a given application and store these settings. The operator-programmed configurations can then be turned on or off with the push of a button on the CommandARM™ controls.
NOTE: Road/loader lights are also referred to as high-mounted driving lights for use in front hitch applications that obscure the headlights. See the Attachments section.
Field-installed options are also available. To find this information, use the Build Your Own Configurator application for US/Canada or Build & Price in John Deere Sales Centre for Australia/NZ.
The battery power saver feature is also standard. When the engine is off and the outside lights have been left on, this feature is designed to avoid battery run down.
After the lights have been left on for 30 minutes and the key is in the off position, the lights cycle or blink on and off five times as an alert. The lights continue to illuminate for one more minute and then automatically shut off to protect the battery.
Another feature is programmable exit lighting. Exit lighting allows the lights outside the cab to stay on for up to 300 seconds. They can be programmed in increments from 0 to 300 seconds.
Refer to the operator’s manual for complete instructions on programming field, driving, and exit lighting.
With ACS, John Deere has designed one of the most robust and full-encompassing steering system in the industry. Whether in the field or on the road, ACS reduces steering effort, which can result in reduced operator fatigue and can improve operator comfort.
There are four key features of the ACS system:
Dynamic road wheel offset:
Variable ratio steering:
Elimination of steering slop and hand wheel drift:
Variable effort steering:
The ACS system is fail operational, which means steering is still functional in the event of any single-point failure. John Deere has gone to great lengths to help ensure the operator has the ability to steer the tractor if something goes wrong in the steering system.
For example, if the primary controller fails, a second controller takes over. If power from the alternator fails, the battery resumes control. If the engine quits running and is unable to supply hydraulic oil to the system, an electric-driven backup pump is used to supply the oil. There is a backup for ACS components.
The ACS system consists of several key components:
The brakes are designed with large-diameter rear disc brakes and powerful activating pistons. The brakes run in oil for cooling and long life in the most demanding situations. Braking in the field during a turn can be accomplished with light pedal effort and excellent modulation of brake forces.
Hydraulically actuated, power wet-disc brakes:
An integrated park brake is included with all transmission options.
Front wet-disc brakes are included on 8R Series Tractors equipped with the 50-km/h (31-mph) Independent-Link Suspension (ILS™) axle and 7R Series Tractors equipped with a 50-km/h (31-mph) Triple-Link Suspension (TLS™) Plus front axle. Front Brakes are optional equipment on the 8R 42-km/h (26-mph) ILS axle and 40-km/h (25-mph) TLS Plus front axles.
Foot brakes on tractors equipped with AutoPowr™/Infinitely Variable Transmission (IVT™) transmissions have an integrated AutoClutch™, as described in the IVT section. Similarly, foot brakes on tractors equipped with e23™ transmissions have integrated AutoClutch™, as described in the e23 section.
For towing very large loads, the 7R and 8R Series Tractors can be equipped with a complete air-brake-system or a hydraulic brake coupler, or both. The brakes supply air or oil pressure to a brake-equipped trailer or implement.
All 8R and 8RT Series 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 wheel models. The dual-pump system provides a hydraulic flow of 321 L/min (85 gpm), ideal for running at lower engine speeds.
SCV flow (approximate)
Pump flow (85-cc pump) L/min (gpm)
High pump flow (85-cc pump + 35-cc optional pump) L/min (gpm)
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 erpm with a 321 L/min (85 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 erpm.
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.
Hydraulic pump options:
The Premium CommandView III cab offers unsurpassed visibility, operator comfort, control placement, and ride and sound quality.
8RT Series Tractors feature the Premium CommandView III cab with cab suspension in base. Producers will enjoy all the features they have come to expect in the Premium CommandView III cab plus the addition of improved ride quality in the field and on the road with the cab suspension. The cab suspension, combined with the proven AirCushion™ suspension system, will give John Deere operators the most comfortable operating experience available in a two-track tractor.
Steering circuit change and steering sensitivity adjustment
8RT Series Tractors include an improved steering pump, changes to the loop-override circuit, and in-cab steering sensitivity adjustment.
The improved steering pump and changes to the loop-override circuit increase steering response and steering authority on 8RT Series Tractors. Operators will notice this change when working in heavy draft, soft field conditions, and obstacle avoidance. The steering pump and loop-override circuit give the 8RT the ability to turn under load like no other two-track tractor in the industry.
8RT steering sensitivity adjusted in the 4600 CommandCenter Display
This feature allows operators to fine tune the steering system based on the application or environment.
Steering sensitivity adjustment does not only help when steering the tractor manually. Operators using guidance systems will also experience improved response with the ability to input tractor tread settings in the 4600 CommandCenter Display. From there, the tractor will control the steering pump to ensure steering is consistent no matter which tread setting the operator is utilizing.
These variable-length sunshades provide excellent adjustability to keep direct sun off of the operator. Perforations in sunshade material provide visibility through the sunshade as well. The sunshades are also recessed into the headliner for storage when not in use.
Right and left outside wide-angle mirrors are electrically adjustable with simple in-cab adjustments to view variable-width implements, wagons, or carts. The in-cab controls are located directly above the radio.
The ComfortCommand seat with air suspension improves ride quality and helps to reduce operator fatigue. The ComfortCommand seat with air suspension is offered with cab suspension. The ActiveSeat™ is available on fixed cab tractors.
The leather seat option is available on 8RT Series Tractors. The kit includes leather operator seat, leather instructional seat, leather-wrapped steering wheel, rear window decal, and carpet floormat.
NOTE: The leather comfort package is not available with Scraper Special Tractors.
John Deere 8RT Series Tractors feature the CommandARM with integrated Generation 4 CommandCenter display. The control layout of the CommandARM utilizes a clean and efficient design which groups controls by function and builds upon John Deere’s history of intuitive and ergonomic control placement and operation. The CommandARM control’s design allows for a 40 degree right seat swivel and adjustable positioning matching the operator’s preference.
Controls located on the CommandARM include:
The design of the CommandARM controls allows for up to 40 degrees of right-hand seat swivel.
John Deere 8RT Series Tractors equipped with the e23 transmission with Efficiency Manager feature or AutoPowr™ IVT transmission feature either a left-hand or right-hand reverser.
The transmission control lever is placed on the CommandARM control’s left side closest to the operator for convenient setting and adjustment.
Hydraulic and hitch controls utilize fingertip paddle pots for raise/lower and extend/retract functions. An optional crossgate joystick replaces fingertip paddle pots for control of SCVs and allows for programmable hydraulic functionality according to operator preference. Rear hitch position can also be controlled with the encoder wheel located on the right side of the CommandARM. The encoder wheel allows for finite positioning of the rear 3-point hitch.
Three buttons near the encoder are for hitch set, lock, and return to height. Adjustment for the 3-point hitch is done via the CommandCenter display.
The throttle design incorporates buttons which control FieldCruise speed, foot pedal mode (if equipped), and transmission eco settings.
Located just to the right of the throttle is the AutoTrac activation button and four sequence controls for iTEC functions.
Controls for radio, lights, rotary beacon (if equipped), hazard flashers, and HVAC system are located to the center-right on the CommandARM, along with PTO for both front (if equipped) and rear.
The Generation 4 CommandCenter displays feature fast adjustment of tractor functions and controls and are integrated into the CommandARM to create a seamless control center. The 4600 CommandCenter features a 26.4-cm (10.4-in.) touchscreen display and is standard equipment on 8RT models.
The following functions can be adjusted using the CommandCenter display:
How exhaust gas recirculation (EGR) works
EGR reduces the high temperatures where nitrogen oxide (NOx) compounds are formed in the engine cylinders by replacing excess oxygen with a prescribed amount of cooled exhaust gas.
Exhaust gases contain more carbon dioxide than oxygen. The EGR valve in conjunction with the venturi and engine control unit (ECU) allows a controlled amount of exhaust gas to enter the intake manifold to mix with the incoming fresh air. Replacing excess oxygen with cooled exhaust gas leads to lower combustion temperatures, creating less NOx. In addition, EGR allows for advanced timing, leading to optimal performance of the engine, maximizing fuel economy.
The following diagrams illustrate how air flows through the engine.
For added performance and efficiency, the engine passes the exhaust gases through an EGR cooler before it enters the engine.
Flow of exhaust during engine operation
Exhaust airflow enters into the EGR cooler from the exhaust manifold near the turbocharger.
Based on engine load, air temperatures, and rpm, the engine control unit (ECU) opens or closes the EGR valve, allowing a measured percentage of exhaust gas to enter the intake manifold.
The gases mix with the rest of the incoming air from the turbocharger and aftercooler before entering the cylinders.
For increased versatility, two 1000-rpm front PTO options are available from the factory for 7R and 8R Series Tractors equipped with the John Deere front hitch.
Front PTO features include:
7R specific features:
8R specific features:
Intelligent Power Management (IPM)
IPM is compatible with 7R and 8R Series Tractors equipped with a front PTO option. The front PTO, rear PTO, or transport speeds can activate IPM on 7R Tractors. However, on 8R Tractors, IPM is only activated by the rear PTO or by transport speeds. For example:
Disconnecting the PTO drive to the PTO box when not in use increases tractor efficiency by reducing:
Refer to the Operator’s Manual for instructions on how to disconnect the PTO when not in operation.
Front PTO engagement is actuated through an engagement switch similar to the rear PTO located on the CommandARM™ controls.
NOTE: For the 8R Series, if the tractor is equipped with a front PTO, additional IPM power will transfer through the front PTO. However, IPM activation is only sensed through the rear PTO. Adequate load must be sensed on the rear PTO in order for IPM to activate.
The John Deere Waterloo Works Gold Key program has been in existence since July 1996 and was designed to recognize and honor those purchasing Waterloo-built tractors.
The Gold Key experience provides the opportunity for you to watch and experience your tractor being built on the assembly line. If you are unable to visit the day your tractor is on the assembly line, the Gold Key owner may elect a day within two weeks before or up to two weeks after the projected warehouse date. If an owner cannot visit during this window of opportunity, they may visit any time at their leisure; however, the tour will be recognized as a VIP visit, and the Gold Key Program will not be deployed.
A Gold Key visit entails a three- to five-hour factory visit touring the assembly production lines. The factory visit is targeted to a three-hour period prior to tractor completion. Up to four participants can be accommodated as a Gold Key tour. Owners and their guests will wear Gold Key owner identification nametags and be escorted privately by tour guides. Every attempt will be made to make sure the owner will see THEIR specific tractor come off the assembly line; however, because of circumstances out of John Deere's control, the first priority is to keep the manufacturing lines running at full capacity in order to satisfy delivery needs.
The Gold Key visit date is determined by factory build schedules, not launch or warehouse dates. It is imperative to notify the John Deere dealer from whom the tractor was purchased in order to initiate the Gold Key experience. The John Deere dealer will in turn be requested to notify John Deere Guest Services as soon as possible if a Gold Key visit is requested. The owner will be presented with a Gold Key and certificate in a recognition ceremony at the conclusion of their factory visit. Lunch will also be included the day of the visit.
Again, the owner will need to notify the John Deere dealer from whom they have purchased the Waterloo-built tractor. Moline Guest Services will coordinate tour requests with the factory Gold Key coordinators. The factory Gold Key coordinator will be the sole contact with the dealership representative to make visit arrangements and confirmations for the visit.
Shortly after the factory Gold Key coordinator receives and processes the request, all appropriate paperwork and information will be sent to the dealer. The Gold Key coordinator will also make direct contact with the owner to confirm the visit. The dealer is asked to share that paperwork and information with the purchaser.
Betty and Steve Ambrose participated in the Gold Key Tour at John Deere Waterloo Works. They purchased a 7930 Tractor.
While every attempt will be made, and the factory will do everything at its disposal to provide the ability for the purchaser to see THEIR specific tractor being built, it should be noted that production schedules change for many reasons. In this case, should production change at the last minute, the owner may arrive only to find that either the tractor has been pushed back or pulled ahead and already built. While that is certainly not our intention, it may happen. Purchasers who do decide to participate need to be aware of this possibility.
The factory cannot be responsible for:
The Generation 4 CommandCenter was designed to provide a consistent user experience by providing full-screen viewing of more run page modules, shortcut keys, and precision agriculture capabilities.
