The Z55 Gehl 5 1/2-metric-ton compact excavator from Manitou is equipped with a 47.6 hp Yanmar Tier 4 turbocharged diesel engine that has an electronic throttle. Eco mode and auto deceleration reduces engine speed by 10 percent without sacrificing power and decreases the engine speed to idle after four seconds without hydraulic movement. Controls include a proportional auxiliary hydraulic rocker switch that enhances attachment options by enabling the operator to adjust the hydraulic flow. The operator can select standard ISO or an optional backhoe control pattern with a turn of a mechanical lever. A boom offset swing of 68 degrees in both directions allows for digging a square hole without repositioning the machine. 262/334-9333; www.manitou.com.
