John Deere 9520R

PTO and shield

Fully independent 1000-rpm PTO is available as a factory- or field-installed option.

• Available on all 9 Family Ag Tractors.
• Full-power capability for maximum utilization*
• 4.45-cm (1-3/4-in.) diameter shaft.

* 9 Family Tractors derate PTO hp when tractor is stationary.

9R – When the PTO is on and ground speed is 0.5km/h (0.31 mph) or less; PTO is limited to 335 hp.

9RT – When the PTO is on and ground speed is 0.5km/h (0.31 mph) or less; PTO is limited to 329 hp.
9RX – When the PTO is on and ground speed is 0.5km/h (0.31 mph) or less; PTO is limited to 335 hp.

See the specs page for model rated PTO horsepower.

The PTO shield has three positions — neutral, up, and down. Use the neutral position when the PTO is connected and ready for use. Use the up position for added clearance when connecting the PTO shaft to the tractor. The down position is used when the PTO is not connected and extra visibility to the drawbar is desired.

Electrohydraulic PTO control

The 9 Family Tractors utilizes an electrohydraulic PTO-engagement switch to activate the optional 1000-rpm PTO.

If PTO option is not installed, a storage compartment is located on the rear of the tractor.

3-point hitch

The 9 Family Tractors are designed to maximize performance for different applications. The 9R, 9RT, and 9RX Series Tractors offer two different hitch options:

CommandARM™ controls

Hitch controls

3–point hitch controls under armrest on CommandARM

To help boost productivity, a field-installed kit with 3-point hitch controls can be purchased. If this option is selected, control buttons will be located on the 9 Family Tractor’s CommmandARM to access individual hitch settings. There are three buttons — set, lock, and load depth. There is also a rotary encoder that allows for finite movements of the hitch. The rotary encoder is detented, so it clicks for each movement. Additionally, hitch adjustment controls are located under the CommandARM for raise/lower rate.

Hitch load depth

The load depth feature is a useful tool designed to increase performance in tillage applications. Load depth adjustments allow the operator to make adjustments to hitch draft responsiveness.

Draft control helps maintain the operating depth in varying conditions, such as rolling terrain, and varying soil densities.

An additional feature with load depth control is the hitch slip option.  Hitch slip uses wheel slip data to supplement the draft control system. If the wheels slip, the 3-point hitch lifts to allow the tractor wheels to maintain traction with the ground. Once the slip condition is no longer present, the hitch lowers to the required depth as determined by the hitch command and load depth settings.

Both of these hitch command options are easily programmable in the CommandCenter display by pressing the load depth shortcut key, followed by using the thumbwheel and confirm key to dial in the desired settings.

Hitch, external remote control switch

For added operator convenience, a 3-point hitch remote control switch is located on top of the left rear fender for 9R, 9RT, and 9RX Tractors. The external remote switches enable the operator to raise and lower the 3-point hitch from behind the tractor while hooking to implements.

Throttle

The throttle design incorporates buttons which control FieldCruise speed, and transmission eco settings. 

CommandCenter

Generation 4 CommandCenter

The Generation 4 CommandCenters feature fast adjustment of tractor functions and controls and are integrated into the CommandARM to create a seamless control center.

The following functions can be adjusted and accessed using the CommandCenter display:

• Hydraulic settings
• Hitch settings
• Transmission settings
• FieldCruise
• iTEC programming functions
• Radio
• Lights
• Add all functionality – diagnostics, display settings, etc.

The Generation 4 CommandCenters have the capability of Remote Display Access (RDA). RDA allows improved communication between an offsite farm manager or dealer and the equipment operator. The user can view exactly what the operator sees on the GS3 2630 Display and Generation 4 CommandCenter from almost any Internet-connected device. RDA is available on the 4600 and 4100 CommandCenter RDA allows for an increase in productivity with quicker problem resolution. By using RDA, the cost of operation will decrease due to reduced labor and travel costs, and maximum efficiency will increase profit.

PowerTech PSS 9.0L engine

The John Deere exhaust filter is integrated into the engine design and
electronics to provide a seamless operator experience. The engine
control unit (ECU) and exhaust temperature management (ETM)
system work together to continuously regenerate the exhaust filter
using a natural cleaning process sometimes referred to as passive
regeneration. If natural filter cleaning cannot be achieved based
on temperature, load, and speed, then particulate matter (PM) must be removed using
an automatic cleaning process sometimes referred to as active
regeneration. In most cases, filter cleaning does not impact machine
operation or require operator involvement. Higher pressures created
by our Final Tier 4 (FT4)/Stage IV high-pressure fuel system extend intervals
between automatic cleanings.

How 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 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 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.

The following diagrams illustrate how air flows through the engine (PSS).

For added performance and efficiency, the engine passes the exhaust gases through an EGR cooler before it enters the engine.

Dual hydraulic pump system

Selective control valve (SCV) stack

Optional high-flow hydraulics are available on 9 Family Tractors by ordering code 3270. The high-flow hydraulic system provides an additional 215 L/ min (57 gpm) of flow for a total of 435 L/ min (115 gpm). This system is ideal for hydraulic fan motor demands. This system is recommended for agricultural implements with continuous flow requirements. When maximum hydraulic pump capacity is reached, multiple functions will continue to operate at the same proportional flow rate.

The 9 Family Ag High-Flow Tractors have two parallel hydraulic systems. The benefit of this system is that functions can be split between the two systems. Functions that require high flow and low pressure can be combined on one system (for example, air seeder fans, and planter motors). Functions that require high pressure and low-flow can be connected to the remaining system (for example, implement lift, fold, and constant down-pressure systems).

Following these guidelines allows the hydraulic system to run cooler as it prevents both hydraulic pumps from running at high pressure. In general, pumps forced to run at both high pressure and high flows generate much more heat than a pump running at a lower flow or lower pressure.

The system operates with two hydraulic pumps:

• Pump 1 - provides hydraulic flow of up to 215 L/min (58 gpm) to SCVs 1, 2, and 3. These SCVs are useful for operating lift/lower and other cylinder type hydraulic needs.
• Pump 2 - attaches in front of pump 1 and provides hydraulic flow of up to 215 L/min (57 gpm) to SCVs 4, 5, and 6. These SCVs are useful for operating hydraulic motors to drive air/fan or vacuum systems on seeding/planting equipment.
• All SCV oil returns to one common hydraulic reservoir.
