8RX and 8R Tractors in the field

All 8 Series Tractors come standard with an 85-cc (5.2-cu in.) hydraulic pump. This pump provides up to 227.1 L/min (60 gpm) hydraulic flow. A dual pump option featuring 85-cc and 35-cc (5.2-cu in. and 2.1-cu in.) displacement hydraulic pumps is available for all 8R and 8RX Tractors. The dual-pump system provides a hydraulic flow of 318 L/min (84 gpm), ideal for running at lower engine speeds. At the rear, up to six selective control valves (SCVs) are available with 1.9-cm (3/4-in.) options.

Single or dual pump options to fit specific producer applications
Up to 318 L/min (84 gpm) through the dual pump system on 8R and 8RX Tractors
Options from four to six factory-installed SCVs
For maximum flow, 1.9-cm (3/4-in.) SCV couplers are available factory and field installed

A power beyond option is available on all models, and a high-capacity take-out oil reservoir (on 8R Tractors only) is also available for high-demand applications.

8RT Tractor with cab suspension and air seat

8RT Tractors naturally offer excellent in-field ride due to the large footprint and an AirCushion™ suspension system. A great ride is also enabled by the lack of power hop due to the track system. 8RT Tractors are equipped with a four-post cab suspension and air seat that is specifically designed for and only found on these models. This system reduces high-frequency vibrations typically associated with road transport and allows 8RT Tractors to strike an unmatched balance in ride quality in the field or on the road. Both the cab suspension and AirCushion suspension are in base equipment on all 8RT Tractors.

Four-post cab suspension with an air seat offers an exceptional ride for operators while on the road.
The cab suspension system specifically designed for 8RT Tractors is offered in base equipment.
8RT Tractors naturally ride well in the field due to the independent track systems and a large footprint.
The AirCushion suspension system not only improves ride quality in the field but also allows the track systems to move freely and independently of the other, maximizing track-to-soil contact and improving overall traction.

Connected Support technology

When you buy John Deere equipment, you expect reliability. You also know that problems can happen, and a product is only as good as the support behind it. That’s why John Deere equipment is prepared with technology that senses potential issues and can alert you and your dealer promptly—in the cab or anywhere you are.

John Deere Connected Support is a revolutionary change to support that leverages technology and the connectivity of JDLink™ telematics to prevent downtime and resolve problems faster. These tools decrease downtime by an average of 20 percent, enabling faster responses to unexpected problems and reducing technician trips to your machine. For some issues, unplanned downtime can even be prevented altogether through prediction of the issue.

With your permission, John Deere Connected Support:

Keeps you running by monitoring machine health and promptly alerting you and your dealer of issues
Saves time by remotely viewing in-cab displays, reducing trips to the machine
Reduces or even eliminates technician trips to a machine through remote diagnostic and remote software reprogramming capabilities
Connects experts with the information needed to respond to downtime faster and prevent it altogether

With more than a decade of experience leveraging connectivity to solve problems, no one else has the experience, tools, and knowledge to keep you running as John Deere and your John Deere dealer can. Connected Support is an in-base feature on all John Deere products with factory- or field-installed JDLink.
