Features

Efficient, More Comfortable 6M Cab

Operator’s view inside John Deere tractor cab showing fabric operator seat, steering wheel, armrest controls, touchscreen displays, and wide windshield overlooking a harvested field.

Your time in the cab can be comfortable and efficient with the 6M interior environment. Built with the operator in mind, we offer three cab customizations, allowing you to select the package that best meets your needs.

Precision Technology to Help Improve Efficiency

Interior of a John Deere tractor cab showing steering wheel, CommandPRO joystick, and multiple touchscreen displays with guidance and machine data, while operating over a grassy field.

Precision ag technology availability includes AutoTrac™ guidance readiness, JDLink™ connectivity, and an intuitive corner post display to help operators improve accuracy, efficiency, and uptime.

Activation required. JDLink hardware comes standard with the machine. You can turn on JDLink Connected service in your John Deere Operations Center™ account for free. JDLink requires a cellular connection to transfer information from machine to a JDLink website. Consult your John Deere dealer for coverage availability.

Built for High-Clearance

Front view of John Deere row‑crop tractor driving between rows of leafy green crops, with large front tires, enclosed cab, and clear blue sky over a cultivated field.

Ground clearance is critically important for bedded crops. The 6MH 155 offers up to 27 inches (68.6 cm) of clearance from the drawbar to ground.
