John Deere 9370r
John Deere 9370r Over the years, the series continues to receive updates with each generation becoming more deluxe features and more power. For 2015 (production is expected to start in November with early ship data from January), the series will now consist of six models (9370, 9420, 9470, 9520, 9570 and 9620) ranging from 370 to 620 HP with tracking (RT) and articulating (R) variants. For the high performance requirements of the scraper market, there are also four specially spiced tractors from 470 to 620 hp.
The new series is powered by three EPA final Tier 4 (FT4) engines with 9370 variants that receive John Deere PSS 9.0 L performance; 9420, 9470 and 9520 get John Deere PSS 13.5 L performance; And the 9570 and 9620 get Cummins QSX15 15.0 L engines. On the Milwaukee Ride N Ride, it was asked why the Cummins power, when John Deere had nearly as high horsepower engines in products such as their marine diesel or generator platforms. The answer was simple, the torque curve and the performance needed to provide the performance expected by 9Rs was more than the John Deere engines could offer. On the ride N Drive, we also learned that the 9R development team was tasked with maximizing value. Three challenge areas were the control of fuel costs, the addressing of power hop and the guarantee of a stable performance in different operating conditions. We will touch on each of the below.
A 9620 carries up to 400 gallons on board fuel and 22 gallon diesel Exhaust Fluid (DEF). For the customer, minimizing the overall liquid consumption is of paramount importance. John Deere dealt with these high costs by aligning 9R tractors with a new E18 PowerShift transmission that, together with efficiency manager electronics, minimizes consumption while maximizing performance.
The transfer offers 18 forward and six backward speeds with 10 of which forward speeds 0.5 mph apart in this critical 3-8 mph range. A rotary wheel setting ensures such an operation, so that the operator does not have to cope with the engine speed and the gear selection. On the CommandARM setting, F1 can be programmed with a speed setting between 2 and 12.6 mph. The F2 setting can be programmed in a range of 2 to 25 mph. Once the setting is selected, the operator can fine-tune the ground speed by turning the knob. In auto mode, the tractor predicts optimal switching points under load, maximizing performance and minimizing fuel consumption.
The John Deere 9 family of tractors have the CommandARM with integrated Generation 4 CommandCenter display. The control layout of the CommandARM uses a clean and efficient design that groups control by function and builds on John Deere’s history of intuitive and ergonomic control placement and operation. The design of the CommandARM allows a 40 degree right seat pivot and an adjustable positioning corresponding to the operator’s preference.
Controls located on the CommandARM include:
- Engine throttle
- Transmission control for e18™ transmission speed PowerShift transmission (PST)
- Eco mode (minimum engine speed) for e18 speed PowerShift transmission (PST)
- FieldCruise™ engine controls
- Selective control valve (SCV) controls

- AutoTrac™ assisted steering system resume switch (if equipped)
- Beacon light on/off
- Hazard lights on/off
- Field lights 1/2
- Heating, ventilation, air-conditioning (HVAC) system
