With a tight tail-swing radius, the ZX135US-6 HP is perfect for contractors working in and around obstacles. The Dash-6 model is equipped with a powerful EPA Final Tier 4 (FT4)/EU Stage IV Isuzu engine that features integrated, effective engine technologies and does not require a diesel particulate filter. It also includes many other customer-driven features such as a standard rearview camera, standard factory installed auxiliary hydraulics with programmable attachment modes, and upperstructure handrails.

The ZX135US-6 HP comes standard equipped with five years of Hitachi’s Global e-Service, giving you 24/7 online access to machine location, health, utilization, fuel consumption, and other valuable information – so you can better understand costs and jobsite performance.

Product Highlights

  • Our FT4 field-proven technology is simple and efficient, employing cooled exhaust gas recirculation (EGR), a diesel oxidation catalyst (DOC) and selective catalytic reduction (SCR). An improved piston design allows particulate matter to be burned in cylinder, so there’s no need for a diesel particulate filter (DPF).
  • Auto-idle, which reduces engine speed when hydraulics aren’t in use, and auto-shutdown contribute to fuel efficiency.
  • The pressurized fuel system improves fuel injector operation, and the fuel recirculation system helps prevent fuel gelling in cold climates – so you can maintain maximum productivity
  • Thick-plate single-sheet mainframe, box-section track frames and industry exclusive double-seal swing bearing deliver rock-solid durability.
