Hitachi debuted the first models in its new Dash-5 lineup. The ZX250LC-5, ZX290LC-5, and ZX350LC-5 will be the first models to arrive at dealers. The ZX470LC-5, ZX670LC-5 and ZX850LC-5 will launch later this summer. Other utility- and construction-sized models, including wheeled and ultrashorts, as well as compacts, will roll out at a later date.
The ZX Dash-5 Series incorporate optimized hydraulics that enable improved arm digging force, bucket digging force, lift capacity, swing speed, swing torque, hydraulic flow, engine horsepower and drawbar pull (varies by model). The roomier cab includes a more comfortable high-back seat available as a heated, air-suspension version. The multifunction monitor provides enhanced diagnostic features and integrates the radio and HVAC controls in one place.
On the ZX250–ZX350 models, the rear hood is low for better visibility to the rear, and there is a new mirror on the counterweight. A hydraulically driven reversible fan for cleaning debris from the radiator screen comes standard on the ZX470 and higher models.
An extended frame houses the updated cooling components and Interim Tier 4 Isuzu cooled EGR engine platform. The exhaust filter consists of a diesel oxidation catalyst/diesel particulate filter with a 5,000-hour service life.

- 54,498- to 76,258-lb. operating weights
- 188- to 271-net hp engines
- 49,935- to 64,375-lbf. maximum traction force
