John Deere and Cummins have partnered to provide customers with a reliable, productive and efficient engine solution in the X15. Extensive work has been done between John Deere and Cummins on software development and other engine/tractor application interface points to provide producers with the performance and efficiency they have come to expect from John Deere. The X15 has followed the same building block approach to meet emissions requirements as similar John Deere engines. This allows John Deere to provide common technologies to producers throughout different horsepower and engine displacement offerings ensuring a consistent experience for producers. Just like the other two engine offerings in the 9 Family of tractors, the X15 features exhaust gas recirculation (EGR) and an exhaust aftertreatment combination of a diesel particulate filter (DPF) and selective catalytic reduction (SCR) to meet the near-zero NOx and particulate matter (PM) emissions standards. X15 technology XPI fuel system – the XPI common-rail fuel system delivers a precise quantity of fuel at ultra-high pressures. This, together with electronic engine controls, enables multiple injection events per cycle. Flexibility in injection timing increases fuel economy and performance while decreasing exhaust emissions. VGT turbocharger – the X15 utilizes a single Cummins VGT™ turbocharger which features electric actuation for infinite adjustment. Cooled EGR –system has been rebalanced for use with SCR, reducing flow volume and minimizing diesel exhaust fluid (DEF) consumption levels. Fully integrated electronic controls – a single electronic control module (ECM) controls everything from air intake to exhaust aftertreatment. Cummins particulate filter and SCR – Cummins particulate filter operates as a nearly passive device, with minimal regeneration required. Cummins and VGT are a trademarks of Cummins Incorporated.

The e18 transmission delivers smooth shifting and intuitive controls in a reliable 18-speed PST transmission. The e18 transmission with enhanced Efficiency Manager is standard equipment on all 9 Series Tractors. The e18 has evolved from more than 50 years of John Deere PowerShift technology. With more automatic features, the e18 is easy to operate for all levels of operators and operations. It features three modes of operation, full AUTO, custom, and manual modes. Full AUTO and custom modes manage the engine and transmission to match the desired ground speed to the field conditions. These two modes are ideal for most conditions and take the guess work out of operation. Manual mode is perfect for operators looking to operate the e18 like a traditional PowerShift by bump shifting and managing the engine throttle to their liking. As the next generation of PowerShift technology, the e18 delivers the strength to handle sudden, high-torque power loads while maintaining responsive, quick, and smooth shifts.

e18 controls

CommandCenter™ controls

The CommandCenter is the central information system for tractors and allows the operator to program various settings tailored to a specific operation. To access the tractor’s transmission settings, press the transmission shortcut button on the CommandCenter shortcut bar. Operating modes The e18 application settings employ three modes to take full advantage of the engine-transmission communication: Full AUTO mode, custom mode, and manual mode.

Full AUTO mode

Full AUTO mode manages the tractor’s engine and transmission inputs to reach and maintain the desired ground speed set by the operator. This means the tractor will manage shifts and engine rpm to operate at the most efficient level possible. Operators can set the maximum forward and reverse speeds for their particular applications. In full AUTO mode the operator can adjust the desired ground speed in two ways, by conducting a traditional bump shift or by rotating the dial on the thumb wheel. When shifting in full AUTO mode, the transmission shifts set speeds and does not always shift gears, meaning the transmission may not necessarily shift gears if it can reach the desired ground speed with a slightly higher or lower engine rpm. Efficiency Manager is automatically engaged while operating in full AUTO mode. As a result, shifting will not take the tractor out of Efficiency Manager in full AUTO mode.

Custom mode

Custom mode operates similar to full AUTO mode but allows operators to adjust operating parameters to meet a specific operation. It can also activate eco mode for a higher level of operation. Eco allows two minimum engine speeds to be set. Operators can turn eco on and off by either pushing the eco button on the side of the throttle or by selecting eco in the transmission settings page of the CommandCenter controls. For example, operators may choose to turn eco on during transport to utilize a lower minimum engine speed and then turn eco off while operating in the field where a higher minimum engine speed is desired. In the advanced settings page, operators can customize the auto shift engine speed droop as a percentage of the full engine speed. In addition, the load anticipation feature can be enabled for the hitch engagement, hydraulic engagement, or both. Manual mode Manual mode operates very similarly to a traditional PowerShift transmission with Efficiency Manager. In manual mode the operator manages the engine and transmission inputs by controlling the shift lever and hand throttle. Efficiency Manager Efficiency Manager is automatically enabled in auto and custom modes. Efficiency Manager can be turned on in manual mode by selecting the set speed one or set speed two button on the CommandARM™ console. The set speed adjuster on the top of the single-lever gear selector allows the operator to dial in the desired ground speed to establish set speed one or two. Once engaged, Efficiency Manager will manage the engine rpm and gear selection to maintain the desired working speed. To reach the desired set speed, the throttle must be set to full engine rpm.

e18 operation

Setting start-up gears The 9 Series Tractors default to 7F and 2R at start up. However, these default start-up gears can be adjusted from 1-13F and 1-3R through the CommandCenter. Refer to the operator’s manual for additional information. 9R Tractor – e18-speed chart for PowerShift transmission (PST) with Efficiency Manager 9R table

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

• Available on all 9 Family Ag Tractors
• 4.45-cm (1-3/4-in.) diameter shaft

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

	9420R/9420RX	9470R/9470RT/9470RX	9520R/9520RT/9520RX	9570R/9570RT/9570RX	9620R/9620RX
Category 4N/3 with quik-coupler, all axle diameters	Optional – 6804 kg (15,000 lb)		Not available
Category 4N/3 with quik-coupler, 120-mm (4.7-in.) axles required	Optional – 9072 kg (20,000 lb)		Not available

Category 4/4N with quik-coupler, 120-mm (4.7-in.) axle required	Optional: 9072 kg (20,000 lb)

CommandARM™ controls

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 Series 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.

Dual hydraulic pump system

Optional high-flow hydraulics are available on 9 Series 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 Series 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.

Eight-section SCV stack for high-flow requirements

For applications requiring continuous high hydraulic flow or multiple 19.1-mm (3/4-in.) hydraulic connections, this SCV stack is designed to maximize efficiency of the hydraulic system while providing additional flow using 19.1-mm (3/4-in.) couplers. Arrangement of the 19.1-mm (3/4-in.) couplers are split between the tractor’s dual hydraulic pumps to even the hydraulic load on each pump. Increasing coupler size from 12.7 mm (1/2 in.) to 19.1 mm (3/4 in.) allows an additional 26.5 L/min (7 gpm) or 17 percent more hydraulic flow through each coupler and reduces backpressure for hydraulic functions such as dual fan motors associated with the Air Power™ 2 system equipped on John Deere C850 Air Carts. With three 19.1-mm (3/4-in.) couplers available, operators can connect to other high-demand functions such as raise/lower. The 19.1-mm (3/4-in.) couplers also allow higher fan motor speeds for high-rate applications and allow more power to the ground due to less restriction on the hydraulic system. NOTE: This SCV configuration is available on all double-reduction) axle 9420R to 9570R Tractors with high-flow hydraulics and all 9RX Tractors with high-flow hydraulics. This eight-section SCV stack does not include hydraulic Intelligent Power Management (IPM) software. Connections to 12.7-mm (1/2-in.) and 19.1-mm (3/4-in.) couplers are quick and simple for operators with a split SCV stack configuration at a comfortable connection height.

Regular service and maintenance are essential to the performance, productivity, and longevity of all farm machinery. Maximum uptime is an important element of productivity.

• 9 Series Tractor service points are quick and simple to check.
• Greater accessibility improves serviceability.

All items in the daily service schedule can be performed without the use of tools:

Machine	DEF tank capacity
9R	120 L (31.7 gal.)
9RT	93.9 L (24.8 gal.)
9RX	120 L (31.7 gal.)

In-line DEF filter

9R, 9RT, and 9RX Tractors feature an in-line DEF filter to help protect the DEF pump from any contamination in the DEF tank. This in-line DEF filter is easily serviced with a drain plug to drain any remaining DEF from the filter housing and a replaceable cartridge-style filter. Severe-duty water separator, if equipped The severe-duty water separator can extend service intervals and helps to protect the tractor’s fuel system from damage associated with lower-quality fuel. Simply open the drain valve on the bottom of the separator and drain accumulated water. NOTE: Cummins® QSX 15 L (915.4-cu in.) engines cannot be equipped with a severe-duty water separator; however, the fuel filter has separating capabilities like the primary filter on John Deere Power System engines.

Engine access

The tilt hood and side panel design provide additional engine compartment protection. The 9R, 9RT, and 9RX hoods feature the same design for access to engine components. Pull out the hood release (located on the front, left side) and tilt hood back to open. Engine side panels are quickly and easily removed for access to periodic maintenance items.

Transmission, hydraulic, and axle oil level

A sight glass for the transmission, hydraulic, and axle oil level is located at the back right side of the gudgeon, indicating proper oil levels, and an oil fill neck is located on the back right side of the gudgeon for the 9R and 9RX Tractors. The oil fill is located on the top of the common reservoir on the left side of the 9RT Tractor and a fill tube is located between the steps and engine of the tractor.

• Provides increased filter capacity compared to previous 9R and 9RT Tractors
• Transmission, hydraulic, and axle oil should be changed every 1500 hours
• Filter should be changed every 1500 hours unless filter restriction code occurs
• Daily and 10-hour inspections of the transmission hydraulic oil level are recommended

NOTE: The tractor should be off and parked on level ground with the hitch in the lowered position when checking the oil level.

• Sight glass observations will be significantly higher with hot oil temperatures and lower with cold oil or if engine has not run long enough.

NOTE: Oil level above the top mark on the sight glass can result in power loss and heat generation during transport applications.

Primary air filter access

On the 9R and 9RX, the primary engine air filter is accessible from the left-hand platform for replacement annually or as operating conditions require. The filter is aspirated and extends filter life in dusty conditions by aspirating more than 95 percent of incoming dust. Aspirator suction is created by utilizing the air flow from the cooling fan. On the 9RT, the primary engine air filter is located at ground level on right side of tractor.

Oil change intervals

Tractors with the 9.0L (549.2-cu in.) and 13.5L (823.2-cu in.) John Deere Power Systems engines feature a 500-hour change interval when using approved John Deere Plus-50™ II oil and a John Deere oil filter. Tractors equipped with the Cummins QSX 15-L (915.4-cu in.) engine have a 400-hour engine oil and oil filter change interval.

• Previous initial oil and filter change at 100 hours is no longer required due to the factory fill of Break-In™ Plus oil.
• If using anything other than John Deere Plus-50 II oil, a 250-hour change interval is required.  CJ-4 must still be used.
• Only use ultra-low sulfur diesel fuel and CJ-4, ACEA E9, or ACEA E6 oil.
• An oil change of 500 hours is possible when using fuel with less than 15 parts per million (ppm) of sulfur, along with John Deere Plus-50 II oil.

See the tractor’s operator’s manual for oil change intervals and further details.

Battery access

The 9R and 9RX battery location is behind the left-hand step assembly. There are three bolts that secure the swinging step assembly that need to be removed to completely access the batteries. The 9RT top step of the platform conceals the tractor’s three 12-V batteries with 2775 CCA (925-CCA each). Tractors with the Cummins X15 engine will have four 12-V batteries in the same location as tractors equipped with John Deere Power System engines. Although the batteries are maintenance free, conditions such as long periods of operation at high ambient temperatures and excessive engine cranking may require adding water.

Battery boost terminal

On the 9R and 9RX, a battery boost terminal is located on the left-hand side of the engine for convenient and proper boost assisted starting.

Fuse and relay panel

The electrical fuse and relay panel is located behind the operator’s seat and just below the cab’s rear window. Simply lift up on the operator manual cover for access.

• Contains easy-to-replace automotive blade-type fuses and relays for quick servicing.
• Spare fuses are provided for each amperage size used.

The diode module contains many of the diodes contained in the system:

• If a diode problem occurs, simply replace the diode module for easy service and increased uptime.
• Relays are also fully interchangeable for quick service.

Electrical system (smart load center)  The electrical system provides a full controller area network (CAN) bus based system on the tractor for improved tractor implement integration and flexibility. Incorporated with the system is a smart load center, which provides fewer fuses, fewer connectors, and simplified wiring for increased reliability. The solid-state load center’s primary function is to control the majority of high-current loads, such as fender floodlights and the horn. This electronic circuitry will monitor loads and voltages to provide fast reaction time and the ability to alert the operator if a circuit overloads or if voltage is out of specification – for example, open circuit (undercurrent) or short circuit (overcurrent).

Cab air filters

The cab fresh air filter is conveniently located beneath the left side of the cab for all 9 Series products:

• External service means no mess in the cab from dusty filters
• Filter housing acts as a dust accumulator compartment
• Hand screw eliminates need for tools
• Replace cab fresh air filter every 1000 hours or sooner if plugged or damaged

Cab air recirculation filter Cab air recirculation filter is located in the roof liner above the operator. 70 percent of the total air volume is recirculated with a blanket effect for enhanced operator comfort.

• Replace cab air recirculation filter every 1000 hours or sooner if plugged or damaged.

Cab air filters are not designed to filter out harmful chemicals. Follow the instructions in the implement operator’s manual and those given by the chemical manufacturer when using agricultural chemicals.

Windshield washer

The windshield washer bottle is optional on 9R and 9RX Tractors and is located on the left side of the tractor near the DEF fill point. On 9RT Tractors, it is located on the right-side frame.

Maintenance-free U-joint

Maintenance-free U-joint bearings require no servicing to reduce maintenance time.

Toolbox

A convenient toolbox is located on the left-hand side of the front frame for tool storage and comes standard on all 9R, 9RT, and 9RX Tractors. 9R and 9RX Tractors have an additional storage box conveniently located on top the left-hand platform. The 9RT has an additional toolbox conveniently located next to the left side of the batteries for additional storage. Cummins is a trademark of Cummins, Inc.

9620R and 9620RX Ag Tractors will have the option of factory- or field-installed seeding hydraulic IPM. The seeding hydraulic IPM package contains both software and hardware components designed to increase the performance of tractors operating implements that require continuous hydraulic power, specifically the John Deere 18.3-m (60-ft) 1895 Separate Fertilizer Placement Drill, 23.2-m (76-ft) 1870 Air Hoe Drill, and C850 Air Cart. Seeding hydraulic IPM provides an additional 18.6 kW (25 hp) in gears 5 through 18 and an additional 37.3 kW (50 hp) in gears 1 through 4 through an air seeding specific drivetrain protection schedule. Rounding out the package is a dual-pump specific SCV stack, which includes eight total SCVs: three 1.9-cm (3/4-in.) SCVs and five 1.3-cm (1/2-in.) SCVs. The 1.9-cm (3/4-in.) couplers allow for an additional 26.5-L/min (7-gpm) hydraulic oil flow, which reduces restriction to high-demand fan motors on air carts and frame raise/lower functions on large air drills. The 1.9-cm (3/4-in.) couplers also allow higher fan motor speeds for high-rate applications and allow more power to the ground due to less restriction on the hydraulic system.

Enabling seeding hydraulic IPM

Features associated with seeding hydraulic IPM (horsepower increase though air seeding specific drivetrain protection) are enabled under the following operating conditions:

• Any one SCV (5 through 8) is set to continuous-flow operation
• Flow rate greater than 50 percent on continuous-flow SCV

More power available

Seeding hydraulic IPM provides a controlled power boost of up to 18.6 kW (25 engine hp) at rated engine speed in gears 5 through 18 and 37.3 kW (50 engine hp) in gears 1 through 4. Power increase is only provided when required and is designed to supplement the additional hydraulic power consumed by systems running dual fan motors such as the Air Power™ 2 system equipped on John Deere C850 Air Carts.

Air seeding-specific drivetrain protection schedule

An air seeding-specific drivetrain protection schedule will be followed when seeding hydraulic IPM operating conditions are met to deliver an increase in power in lower gears. The specific schedule is tuned to provide additional horsepower in lower gears during high-demand events such as traversing hills and towing large air drills/air cart combinations. Below is a comparison between a base model drivetrain protection schedule with SCV in continuous flow and air seeding-specific drivetrain protection schedule.

Base model (SCV on) vs. air seeding-specific drivetrain protection schedule
Gear	9620R/RX (SCV on)	9620R/RX (seeding hydraulic IPM on)
1	406.4 kW (545 hp)	443.7 kW (595 hp)
2	406.4 kW (545 hp)	443.7 kW (595 hp)
3	425 kW (570 hp)	462.3 kW (620 hp)
4	443.7 kW (595 hp)	481 kW (645 hp)
5	462.3 kW (620 hp)	481 kW (645 hp)
6	462.3 kW (620 hp)	481 kW (645 hp)
7	462.3 kW (620 hp)	481 kW (645 hp)

SCVs for seeding hydraulic IPM

The hardware set is designed to maximize efficiency of the hydraulic system while providing additional flow through the use of 1.9-cm (3/4-in.) couplers. Arrangement of the 1.9-cm (3/4-in.) couplers are split between the tractor’s dual hydraulic pumps to even the hydraulic load on each pump. Increasing coupler size from 1.3 cm (1/2 in.) to 1.9 cm (3/4 in.) allows an additional 26.5 L/min (7 gpm) or 17 percent more hydraulic flow through each coupler and reduces backpressure for hydraulic functions such as dual fan motors associated with the Air Power 2 system equipped on John Deere C850 Air Carts. With three 1.9-cm (3/4-in.) couplers available, operators can also connect to other high-demand functions such as raise/lower. The 1.9-cm (3/4-in.) couplers also allow higher fan motor speeds for high-rate applications and allow more power to the ground due to less restriction on the hydraulic system. Control, settings adjustment, and monitoring of all SCV functions are performed through the CommandARM™ controls and the Gen 4 display. Connections to 1.3-cm (1/2-in.) and 1.9-cm (3/4-in.) couplers are quick and simple for operators with a split SCV stack configuration at a comfortable connection height.
