ORIGINAL EQUIPMENT
The HX55ACR has an operating weight of 12,600 lb (5,715 kg) and a dig depth of 12 ft, 8 in (3.86 m).
All four new machines feature engines
that are Tier 4 Final compliant.
The Hyundai HX17AZ excavator is powered
by a Kubota D902 diesel engine
with a net power rating of 16.0 hp (11.9
kW), while the HX27AZ features a
Kubota D1305 engine rated at 24.4 hp
(18.2 kW). The HX55ACR uses a Yanmar
4TNV86CT engine that delivers 47.6 hp
(35.5 kW), while the HX60A employs a
Hyundai DM02VB engine rated 63.0 hp
(47.0 kW) at 2,400 rpm.
The HX55ACR and HX60A are
equipped with a standard load-sensing
hydraulic system that reduces wear on
hydraulic components while helping to
ensure reliable performance. The HX17AZ
and HX27AZ feature conventional open
center hydraulic systems. Standard adjustable
hydraulic flow control through
the cluster on all four models lets the operator
set optimum flow range for multiple
attachments and switch between
them, using a two-way diverter valve that
directs hydraulic flow to either of two
attachments simultaneously.
The HX55ACR and HX60A models
offer standard blade float, which automatically
forces the blade down to ensure
consistent backfilling and grading.
Auto engine idle, also standard on the
HX55ACR and HX60A, optimizes fuel
efficiency by reducing engine speed
when the excavator is not in use. And
standard auto-shift travel speed allows
seamless transition between high and
low travel speeds.
The HX17AZ has an operating weight
The HX60A is equipped with a standard load-sensing hydraulic system that reduces wear on
hydraulic components.
According to Hyundai, this ensures that
the excavator operates efficiently without
unnecessary fuel consumption or
strain on the engine.
" SPC helps keep the excavator running
longer, " Hodges said, " because it keeps
the machine operating within optimal
power ranges, which reduces wear and
tear associated with overloading or inefficient
operation. This extends the life of
critical components, including the engine,
hydraulic system and attachments. "

Four of a kind
Rounding out Hyundai's recent expansion
news are four new HX-A compact
hydraulic excavators. The HX-A series
first made its debut at CONEXPO in
2023 and now includes a total of eight
models. The latest machines are the
HX17AZ, HX27AZ, HX55ACR and
HX60A. The HX17AZ and HX27AZ are
zero tail-swing machines for working in
confined spaces. The HX55ACR is a
compact-radius model.
of 4,370 lb (1,980 kg), dig depth of 8 ft
(2.44 m), and bucket breakout force of
3,668 lbf (1,664 kgf). The HX5527AZ has
an operating weight of 6,140 lb (2,478
kg) in its canopy configuration, dig
depth of 8 ft, 10 in (2.7 m), and bucket
breakout force of 4,613 lbf (2,093 kgf).
The HX55ACR has an operating
weight of 12,600 lb (5,715 kg), dig
depth of 12 ft, 8 in (3.86 m), and bucket
breakout force of 8,354 lbf (3,789 kgf).
The HX60A in its standard cab configuration
has an operating weight of
13,580 lb (6,160 kg), dig depth of 12 ft, 4
in (3.77 m), and bucket breakout force
of 9,461 lbf (4,292 kgf).
