Sit back and relax. You're looking at one of the most comfortable seats in the business. The all-leather, heated, ventilated seat features nine vertical and lateral adjustments, back support and a larger seat cushion than before.

More peace and quiet. All-new sound suppression enhancements include a noise-reducing hydro-drive plate, cab insulation, gaskets and isolators to help you get away from it all.

Deluxe sound system. Fire up the new first-class stereo system with 4" x 6" speakers and a subwoofer for all-day listening pleasure.

Big screen monitor. You'll be amazed at the crisp clarity of the high-resolution GreenStar™ 3 CommandCenter™ display. All-new cornerpost display gives you key machine information at a glance. You've got to love the latest technological advances all working together so you don't have to.

Sprayer controls at your fingertips. The smart sprayer-specific CommandARM™ gives you fingertip control of important sprayer functions. John Deere integrated technologies help you with the challenges of balancing the right sprayer adjustments all day for peak efficiency.

Conveniences at arm's reach. Integrated BlueTooth® connectivity. A 12-volt power port for your devices. An electronic adjustable right-side mirror for clear view to the rear of the sprayer.

Easy delivery. The compact size allows for easy trailer loading and storage in smaller buildings.
