The MechMaxx MEC12 is a 1.2 ton mini compact excavator with an operating weight of 2700 lb. It is powered by a Kubota D722 water-cooled, 3-cylinder engine rated at 13.7 hp at 2500 rpm. The hydraulic system is a load-sensing design with a variable displacement piston pump.
The track system retracts and extends. Track width is 34.6 in retracted and 42.7 in expanded, so the machine can be set narrow for tight passages or wide for stability. Travel has two speeds: high at 2.24 mile/h and low at 1.12 mile/h.
The machine reaches a maximum digging depth of 65.7 in and a maximum digging radius at ground level of 118.7 in. The upper structure rotates 360 degrees, and the boom swings 53° left and 40° right. A hydraulic thumb is included and can be adjusted from the operator's seat.
