WA270-8 Wheel Loader

Now powered by a low emission Tier 4 Final-compliant Komatsu engine, our 1.9-2.8 m3 capacity WA270-8 features Komatsu’s PZ parallel-lift arm system and hydrostatic drive, for maximum versatility and productivity across loading, handling and lifting applications. As with all our wheel loaders, key components are designed and manufactured by Komatsu to work together in an integrated package. And it comes standard with our KOMTRAX remote monitoring and location system, backed by our NZ-wide service and support network.

  • 111 kW / 149 HP
  • 12,880 kg
  • 2.3 m³

Versatile PZ Linkage

The WA270-8 combines the best of a Z-Bar linkage and a PZ linkage while maintaining parallel lift. The bucket auto rollback feature tilts the bucket back as the boom raises to eliminate spillage, similar to a traditional Z-bar machine. Return to level can be set for both a bucket and fork or other attachment. Switching between the two is done with a switch in the cab.

Komatsu SmartLoader Logic

Komatsu's SmartLoader Logic controls engine torque to match machine demands. This system optimises engine torque for all applications to minimise fuel consumption. Komatsu's SmartLoader Logic functions automatically and doesn't interfere with operation, saving fuel without decreasing production

Komatsu Diesel Particulate Filter and Selective Catalytic Reduction System

The KDPF and SCR reduces particulate matter and NOx while providing automatic regeneration that does not interfere with daily operation
