The Hitachi SX604 is a construction machine from Hitachi, built in Japan, with all-wheel drive and a water-cooled diesel engine. The register holds no power, weight or dimension data for this machine, so the drive layout is its most telling feature.
With all-wheel drive the engine powers all four wheels through a transfer case and axles. The benefit lies in tractive effort and gradeability on loose, wet or sloping ground, since every wheel contributes traction. Against that stand higher cost, more weight and more maintenance for the extra driveline parts. Water cooling keeps the engine temperature in a narrow band even under continuous full load, as is usual in earthmoving; diesel is entered as the fuel, the standard for construction machinery because of its high torque at low engine speed.
Hitachi Excavators – From the First Domestic Hydraulics to Mini Excavators
Hitachi's construction-machinery history began in 1949 with the U05, the first mechanical excavator developed entirely with domestic Japanese technology. In 1965 came the UH03, the first fully Japanese-developed hydraulic excavator built without foreign technical assistance. Its two-pump, two-valve system markedly improved control and later became the de facto worldwide standard for such hydraulic systems. In 1991, Hitachi launched five mini-excavator models, deliberately expanding this segment; the ZAXIS UR series later followed, offering an especially tight turning radius for work in confined spaces. Listed in the register: SX604.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
