With the new Dash-6 model of the WA150 wheel loader powered by a 98-horsepower Tier-3-certified engine, Komatsu's hydrostatic transmission allocates only as much power as is needed for a given application. Engine output is transmitted hydraulically to a transfer case, then mechanically out to the differentials and to the four driving wheels. A new "S-mode" provides maximum driving force on slippery surfaces by controlling the engine speed and transmission motor when traveling at slow speed. The Komatsu WA150-6 wheel loader has an operating weight up to 17,461 pounds, a heaped bucket capacity range of 1.7 to 2.2 cubic yards, and a breakout force of 16,310 pounds.
