Power Train Electronic Control System
Smooth and Soft Operation
D375A-5 uses a newly designed power train electronic control system. The controller registers the amount of operator control
(movements of lever and operation of switches) and machine condition signals from each sensor, and calculates to accurately
control the torque converter, transmission, steering clutches and brakes for optimized machine operation. The ease of operation
and productivity of the new D375A-5 is remarkably improved by numerous new functions.
Electronic Controlled
ECMV (Electronic Controlled Modulation Valve) Controlled Transmission Modulation Valve (ECMV)

Controller automatically adjusts each clutch engagement depending on travel
conditions such as gear speed, revolution and shifting pattern. This provides
smooth, shockless clutch engagement, improved component reliability,
improved component life and operator riding comfort. Time

ECMV (Electronic Controlled Modulation Valve) Controlled Steering Clutches/Brakes

Sensors monitor machine operating conditions, and electronically control steering clutches and brakes depending on type of
job, such as size of load during dozing, incline angle of slope or load, providing smooth and ease of operation by reducing
counter-steering on downhill travel, etc.

Effect of ECMV Steering Clutches/Brake Control

smooth dozing operation.

Preset Travel Speed Selection Function

Preset travel speed selection function is standard equipment, enabling the operator to select fore and aft travel speed
among three preset patterns such as F1-R2, F2-R2 and manual shift. When F1-R2 or F2-R2 preset pattern is selected, and
travel control joystick moves to forward/rearward direction, the machine travels forward/rearward with F1-R2 or F2-R2 speed
automatically. This function reduces operating hours and operator’s gear shifting time during repeated round-trip operations.

provides comfortable operation without manual downshift

CRAWLER DOZER

Large Blade
Capacities of 18.5 m3 24.2 yd3 (Semi-U dozer) and 22.0 m3 28.8 yd3 (U dozer) yield outstanding production. High-tensile-
strength steel comprising the front and sides of the blade increases durability.

Dual Tilt Dozer

The dual tilt dozer increases productivity while reducing operator effort.

● Optimum blade cutting angle for all types of materials and grades can be
selected on-the-go for increased load and production.
● Digging, hauling, and dumping are easy and smooth with less operator fatigue.
● Dozer tilt angle and tilt speed are twice that of a conventional single tilt system.

Rippers (optional)
● The variable giant ripper features a long sprocket center-to-ripper point distance,
making ripping operation easy and effective while maintaining high penetration force.
● The variable giant ripper is a parallelogram single shank ripper ideal for ripping up tough material. The ripping angle is
variable, and the depth is adjustable in three stages by a hydraulically controlled pin puller.
● The multi-shank ripper is a hydraulically controlled parallelogram ripper with three shanks.

Track Shoe Slip Control System (option)

● Eliminates the need for the operator to constantly control engine power output with the decelerator
while ripping. Operator fatigue is substantially reduced.
● Maneuverability is improved because the operator is free to focus on the ripping application without
having to monitor the track shoe slippage.
● Repair costs are significantly lowered and undercarriage life is prolonged with the reduction in track
shoe slippage.
● The track shoe slip control system will contribute to lower fuel costs, because the engine output is
automatically controlled to optimum levels for operation.

Comfortable Ride with New Cab Damper Mounting

and K-Bogie Undercarriage
D375A-5’s cab mount uses a newly designed cab damper
mounting which further improves viscous damper and
provides excellent shock and vibration absorption capacity
with its long stroke. The cab damper mounting, combined
with new K-bogie undercarriage, softens shocks and
vibrations while traveling over ripped ground that are
impossible to absorb with conventional cab mounting
methods. The soft spring cab damper isolates the cab
from machine body, suppressing vibrations and providing
a quiet, comfortable operating environment.
