The SK55SRx is a short-radius mini excavator that comes in both cab and canopy models. The 11,050-pound machine has a Tier 4-Final 37.4-horsepower water-cooled Yanmar diesel engine that includes an “Energy Conservation Mode,” engaged with the push of a button when the work at hand allows the operator to run the equipment at lower power and performance levels. A one-touch deceleration button makes it easy to switch to an idling state, further reducing fuel consumption while the machine is at rest, Kobelco says. The unit has an arm force of 5,530 pounds and a two-pin bucket force of up to 11,128 pounds. Dig depth of 12 feet 10 inches, with a 20-foot 6-inch reach at ground level.
