The HM400-1 has been designed to keep service time down and productivity up by
having a lubrication-free oscillating hitch, a reduced number of grease points, easy
access to filters, and longer intervals between oil changes.
Fewer Grease Points
We have minimized the
number of grease points by
using maintenance-free
rubber bushings and a
lubrication-free oscillating
hitch.

Wide, Spacious Cab
The wide cab provides a comfortable space for the
operator and a full size buddy seat. Large, electrically
operated windows and the operator's seat positioned to
the left side ensure superior visibility.
Ergonomically Designed Cab
The ergonomically designed operator's compartment
makes it very easy and comfortable for the operator to use
all the controls. The result is more confident operation by
operators and greater productivity.
Viscous Cab Mounts
Viscous mounts reduce the noise
transmitted to the cab and achieve
a quiet 76 dB(A) noise level.
Steering Wheel and Pedals
Low effort pedals reduce driver fatigue when working
continuously for long periods. The tiltable, telescoping
steering column enables operators to maintain the
optimum driving position at all times.
Built-in ROPS/FOPS
These structures conform to ISO 3471 and SAE J1040-
1988 standards.
Hydropneumatic Suspension for All Terrain
The hydropneumatic suspension assures a comfortable
ride even over rough terrain and ensures maximum
productivity and operator confidence.
Air Suspension Seat
The air suspension fabric covered seat which is adjustable
to the operator's weight is provided as standard. The air
suspension seat dampens vibrations transmitted from the
machine and reduces operator fatigue as well as holding
the operator securely to assure confident operation.
Electric Body Dump Control Lever
The extra light lever makes dumping easier than ever.
Supplementary Steering and Secondary Brakes
Supplementary steering and secondary brakes are
standard features.
Steering: ISO 5010-1992, SAE J1511
Brakes: ISO 3450-1996, SAE J1473
Easy-to-See Instrument Panel
The instrument panel makes it easy to monitor critical
machine functions. In addition a caution light warns the
operator of any problems that may occur. Problems are
recorded in the monitor and indicated as servic codes.
This makes the machine very friendly and easy to service.
Komatsu has developed a state-of-the-art, wide
comfortable cab. The low level of vibration and noise
ensures maximum productivity from the operator.
