The ZX135US-6 and ZX245USLC-6 reduced-tail-swing models are equipped with a Tier 4-F Isuzu engine that does not require a DPF.
A rearview camera, factory-installed auxiliary hydraulics with programmable attachment modes, and upperstructure handrails are standard. The hydraulic system balances engine performance with hydraulic flow, and the hydraulic boost system and enhanced boom recirculation generate aggressive boom and arm speed, Hitachi says, returning the arm to dig faster. The ZX245USLC-6 features a three-pump hydraulic system that provides even more flow. When demanded, the third pump supplies additional hydraulic oil to the swing circuit without diverting oil and speed from other functions.
