By using the adjustable-width tracks of the undercarriage and the foldable end-sections of the backfill blade, operators of Hitachi's new 1.7-metric-ton Zaxis 17U-2 compact excavator can reduce machine width to 40 inches for easy passage through standard doors. When fully extended to 50 inches, the ZX17U-2's undercarriage provides stability to put the machine's mechanical quick coupler/hydraulic attachment package to full use on the job. An upgrade of the Hitachi EX17U, the ZX17U-2 joins the ZX27U-2, ZX35U-2 and ZX50U-2 in the Hitachi compact excavator family.
