Service ADVISOR

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

• Engine oil, hydraulic oil, coolant level, and water separator can be conveniently accessed from ground level without having to open the hood. Engine oil can be checked by simply removing one small engine side panel.

• Engine can be easily accessed by simply raising the one-piece hood and removing two engine side panels for more periodic maintenance checks.
• Single-point latch mechanism ensures easy hood opening and closure.

The PowerTech 13.5L (824-cu in.) Tier 2/Stage II engine will deliver horsepower and performance ratings and peak torque levels comparable to the PowerTech Plus FT4/Stage V engine.

• Four-valve cylinder head
• Fixed geometry turbocharger with air-to-air after cooling
• Common size intake and exhaust valves
• Targeted spray oil cooled pistons
• Full-authority electronic controls

Reduced fuel consumption

A combination of advanced design features contained in PowerTech 13.5L (824-cu in.) engines and surrounding tractor systems work together to provide the most efficient use of engine power, resulting in less fuel consumption. These features include:

• A fixed geometry turbocharger and single injector electronic control
• The integrated pressure-and-flow-compensated hydraulic pump circuit design adds a priority valve for steering and brakes, reducing engine load when hydraulic functions are not being used.
• The drivetrain and brake system are focused on limiting oil windage losses that reduce available engine power and increase fuel usage.
• e18™ PowerShift™ transmission with Efficiency Manager™ feature allows the tractor to operate at an optimal performance level while minimizing fuel consumption (refer to the Efficiency Manager sections for further information).

9RX Tractors equipped with 304.8-cm (120-in.) track spacing provide increased stability, allow producers to operate on 304.8-cm (120-in.) centers for controlled traffic farming, and provide improved track-to-frame clearance for better access to the undercarriage for serviceability and material cleanout. John Deere is the first and only tractor manufacturer to offer a 304.8-cm (120-in.) track spacing option on four-track tractors with 76.2-cm (30-in.) and 91.4-cm (36-in.) tracks up to 462.3 kW (620 hp).
