Two-Track Tractor

• Engine hp1: 374 Max | 340 hp Rated

Features May Include: 

Customize your Selective Control Valve (SCV) configurations

• 7, 8 and 9 Series tractors offer a SCV stack aimed at improving performance and aftermarket serviceability. These valves further enable customers to fine-tune hydraulic flow rates and make it easier and more affordable to customize an SCV stack. Now you can switch coupler sizes without having to change an entire SCV slice.

8 Series Visibility packages let you run with confidence, dawn until dusk

• Visibility is more than just lighting. It’s mirrors where you need them, shades for the blinding late-fall and early-spring sun, wipers to help keep all the glass clear, and integrated camera capability. The 7 and 8 Series Tractors let you choose the visibility package that best suits your needs – Select, Premium, or Ultimate with 360-degree light-emitting diode (LED) lighting –so you and your operators can run with all-conditions confidence.

Increase ride comfort during all seasons with 8RT suspension options

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
