Powered by the Cummins QSL9 Certified Tier-4 Final engine, the ZW330-6 does not require a diesel particulate filter, which reduces maintenance and parts costs. Combined with the lock-up transmission, it enhances fuel efficiency while travelling. In hill-climbing environments the machine speed is further enhanced. It’s impressive full turn tipping load at 39,300 lbs. is a leader in its class and a testament of its strength and balance.
