PERFORMANCE FEATURES
Innovative SIGMADOZER
Based on a completely new digging
theory, SIGMADOZER dramatically
improves dozing performance and
increases productivity. A new frontal
design concept adopted for digging
and rolling up at the center of the blade
increases soil holding capacity,
simultaneously reducing sideway spillage.
Reduced digging resistance produces
smoother flow of earth, enabling the
dozing of larger quantities of soil with
less power. In addition, adoption of a new
blade linkage system holds the blade closer
to the tractor for improved visibility, enhanced
digging force and reduced lateral sway of the
blade. This is the new generation blade now in its
third model generation.
New Fuel Efficient Bulldozer
New D155AX-8 has achieved both high levels of produc-
tivity and fuel economy through usage of SIGMADOZER
and automatic transmission with lockup torque converter.
