The Utility Division of Komatsu America has refined models in its backhoe-loader line with the addition of available joystick controllers for the backhoe. These "excavator-style" controls will be offered on the WB140-2N, WB140PS-2N (Powershift); WB150-2N, WB150PS-2N, and the WB150AWS-2N (All-Wheel-Steer). Other recent "upgrades" to these models include increased hydraulic speed and Tier-2-compliant engines.
