Ergonomically designed cab

You’ll love the cab for the EX1900-6.The ergonomic layout means you’ll do less stretching and reaching. The roomier seat and cab will make you feel comfortable and well supported, with plenty of leg room. And the high height and forward-sloping cab provides a view that boosts productivity. The cab is pressurized to keep out dust while maintaining a comfortable temperature.

Air-suspension seat

The air-suspension seat automatically adjusts to your weight, and you can custom-fit the controls to your size and operating style. Electric joystick controls have a feather touch, making long periods of operation effortless.

LCD monitor

The 10.5-inch color LCD monitor is the easy to read and will provide you with key data about the excavator. It will display instant-fault diagnosis through all sensors, displaying warnings and countermeasures if failures arise. 

Simplified maintenance

On the EX1900-6, you’ll have easy access to routine checkpoints and critical components, making inspections and maintenance much easier. The walkway is easily accessible and inspection doors open wide.
