NXT2 upgrades have been applied to the 450 Z zero-tail-swing excavator, including a Yanmar Tier 4 engine that has an electronic throttle. A new ECO mode will reduce the engine speed by 10 percent without sacrificing power, the company says; and auto deceleration mode decreases the engine speed to idle after four seconds without hydraulic movement. The operator controls now include a proportional auxiliary hydraulic rocker switch that allows the operator to adjust the hydraulic flow to attachments. Serviceability improvements include tool-free access via large swing-out doors on the back and right-hand side of the machine. These compartments reveal the entire engine and daily maintenance points: radiator, oil cooler, battery and fuses.
