Achieve maximum performance on the job with up to a 17% increase in horsepower from the CASE Tier-III certified Isuzu engine. Digging force is increased by 10% with the Auto Power Boost feature while overall operation is simplified with three work modes on the right hand console: Automatic, Heavy and Speed Priority.

Fuel Efficiency

Meet current environmental standards and consume less fuel with Tier III-certified engines.

Comfort and Visibility

Ultra-low sound levels are provided by the isolation-mounted cab. Attachments are easily viewable both overhead and in the trench thanks to narrow posts on the cab and a one-piece, right-hand window with a clear view to the inside of the right track.
