Kubota Mini Compact Excavator Kubota D722 Engine, 65.7″ Max. Digging Depth, 1.2 Ton, 2700 LBS Operating Weight, MEC12

Diesel replaces gas on this mini excavator: a 3-cylinder Kubota D722 engine producing 13.7 horsepower drives a 1.2-ton machine with an operating weight of 2700 pounds, a step up from the gas-powered entry model in this lineup. What diesel changes day to day A small diesel like the D722 tends to deliver steadier pulling power at low engine speeds than a similarly sized gas engine, which shows up most when the bucket is loaded rather than idling between digs. The hydraulic system here uses load-sensing control through a variable displacement piston pump, meaning flow adjusts to what the attachment is actually doing instead of running at one constant rate regardless of load. Reach and travel This machine digs down to 65.7 inches at full reach, with an 8 rpm swing speed for rotating the house during side-dumping. On the road between digging spots, high range tops out at 2.24 mph and low range at 1.12 mph - slow enough that trailering between job sites makes more sense than driving it there. What engine does this excavator use? A 3-cylinder Kubota D722 diesel rated at 13.7 horsepower. Why does the hydraulic system matter here? Load-sensing control with a variable displacement piston pump adjusts flow to the task rather than running at a fixed rate. New condition. Kubota warranties the D722 engine for 2 years, while the excavator chassis carries its own 1-year coverage. Diesel exhaust from equipment like this falls under California's Proposition 65, which requires disclosing it as a cancer and reproductive-harm risk in that state.
