8 Locking up thetorque converter eliminatesloss of horsepower by 10%.Because the electronicallycontrolled engine is extremelyefficient, a decrease in fuelconsumption is realized whilealso maintaining on a completely new digging theory, SIGMADOZER dramatically improves dozing performance and increasesproductivity. A new frontal design concept adopted fordiggingand rolling up at the center of the blade increasessoil holding capacity, simultaneously reducing sidewayspillage. Reduced digging resistance produces smootherflow of earth, enabling the dozing of larger quantities of soilwith less power. In addition, adoption of a new blade linkagesystem holds the blade closer to the tractor for improvedvisibility, enhanced digging force and reduced lateral swayof the blade. This is the new generation transmission with lockup torqueconverterA sharp reduction in fuel consumption and greater powertrain efficiency is achieved by the new automatic gearshifttransmission and lock up torque converter.

9 The automaticgearshift transmission selects the optimal gear rangedepending on the working conditions and load placed onthe machine. This means the machine is always operatingat maximum efficiency.

Automatic gearshift modeThe mode for general dozing. When a load is applied, the gear automatically shifts down, and when the load is off, itautomatically shifts up to a set maximum gear speed. This mode economizes both fuel and production where the torqueconverter lockup mechanism is actuated according to load, automatically selecting the optimum gear speed.
