Model WA270-7 wheel loader replaces both the WA250-6 and WA250PZ-6, and uses the company's Parallel Z-bar loader linkage to provide 10 percent more lift force. Tier 4-lnterim Komatsu SAS6D107E-2 engine provides 149 horsepower, and the operating weight is 28,836 pounds. Komatsu SmartLoader Logic automatically decreases engine torque when the loader isn't working as hard and doesn't interfere with operation, saving fuel without decreasing production, the company says. Dynamic-braking slows down the machine when the accelerator is released. The electronically controlled HST drivetrain features Komatsu Traction Control System that helps facilitate operation in soft or slippery ground.
