HUGE PERFORMANCE ON ALL KINDS OF JOBS.

The Hitachi ZX50U-5 is a small machine that gives you huge performance on all kinds of jobs. And its reduced footprint doesn’t mean you’ll sacrifice efficiency, reliability or durability with a fuel-efficient and reliable engine that meets emission standards.

FEATURES

ADVANCED HYDRAULICS

Full hydraulic pilot levers used for the front attachment, boom, swing travel and blade. 1-way/2-way selector valve used for attachment mode.

VERSATILE CONTROLS

Auxiliary function lever (AFL) includes trigger, horn and analog switches that can be used for various attachments, like a breaker.

STRONG STRUCTURE AND UNDERCARRIAGE

Variable track width undercarriage with pin-type blade stowage system allows tight access.

EASY MAINTENANCE

Wide-open covers ease maintenance. Parallel-arranged cooling package facilitates cleaning.

COMFORTABLE CAB

3-pillar canopy, compatible with ROPS and OPG (Level 1) provides optimal visibility.

DURABLE BOOM/ARM

Boom hoses are routed to protect from damage. HN bushing applied on front attachment joints provides better grease retention.
