Both the 6M and 6R Series tractors offer high performance, convenience, and advanced technology. The 6M Series has innovative visibility features, while the 6R Series specializes in fuel efficiency and features that optimize its power-to-weight ratio.

Redesigned Hood

Both the 6M and 6R Series tractors provide clear visibility, but the 6M Series tractors feature a new sloped hood design and panorama roof so you can see everything — your front loader, attachments, and front-mounted implements.

Reimagined Cab

The 6M Series tractors are equipped with a comfortable cab and convenient features such as a digital corner post display and the compact CommandARM™. 6R Series tractors are outfitted with the quiet Premium Cab — fitted with air suspension seats, optional hydraulic cab suspension, and ergonomic controls.

Intelligent Power Management

Both the 6M and 6R Series tractors use Intelligent Power Management (IPM), which delivers rated engine horsepower with a 10% power bulge under load. IPM also provides a power and hydraulic boost when specific conditions are met, ensuring consistent performance without overloading the drivetrain.

Power-to-Weight Ratio

While both 6M and 6R tractors can boost power when needed with IPM, the 6R Series in particular offers an efficient power-to-weight ratio that helps you maximize production.

Reversible Fan

The 6R Series Tractor’s reversible fan not only improves fuel consumption and engine cooling, it keeps your radiator screens clear of chaff and debris from the field and from the cab. 

Improved Visibility

Whereas 6M Series tractors use a sloped hood design and panorama roof for optimal visibility, 6R Series tractors improve visibility by placing common displays on corner post displays. 6R tractors also offer a larger windshield wiper sweep area.

Dynamic Weighing

The dynamic weighing feature on the 6R Series lets you weigh feed and bales on the go, saving you the cost of buying a separate feeder wagon scale. Eliminating the guesswork also saves time by enabling you to load weight accurately.
