9520RX Scraper-Special

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.

• Heating, ventilation, air-conditioning (HVAC) system

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 Family 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 have the ability to 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 also has the ability to 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.

The 115-gpm (435 L/min) hydraulic system (order code 2813) is designed to reduce scraper hydraulic cycle times, thus increasing the efficiency of the tractor/scraper combination.
 
Two hydraulic pumps are combined for a total of 115-gpm (435 L/min).  Flow through one 19.1-mm (3/4-in.) SCV is 45 gpm (140 L/min). The selective control valves (SCVs) are designed for commercial applications. This system is not 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. This will prevent the rear scraper from slowing down, in relation to the front scraper, when operating the front and rear scrapers at the same time.
 
When ordering this scraper high-flow option, the tractor will come standard with four SCVs. The two system pumps provide their combined oil flow of 115 gpm (435 L/min) to all four SCVs through a common valve manifold. All of the SCV oil returns to one common reservoir.
 
19.1-mm (3/4-in.) couplers reduce restriction for increased flow to the scraper. A secondary lowering function accumulator is included with the hydraulic valves so the scraper can be lowered if hydraulic power is lost.

NOTE: This system is not recommended with agricultural implements with continuous flow demand (scraper applications only).

 
IMPORTANT: Do not use this system with scrapers/implements with 12.7-mm (1/2-in.) couplers/hoses/hydraulic systems. Damage could occur to implement hoses/couplers/components due to high-flow capability of the tractor system.

 

NOTE: Power Beyond connections are not recommended for use with scraper systems or high hydraulic oil take out demand (example: large or multiple single acting cylinders, raising multiple scraper pans). Power Beyond connections are recommended for agricultural equipment with continuous flow demands (example: variable rate drives, CCS fans).

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 Family service points are quick and simple to check.

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 Series Tractor. The oil fill is located on the top of the common reservoir on the left side of the 9RT Series 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 Series 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 9.0 L (549.2-cu in.) and 13.5 L (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.

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 Family 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.
