The Chicago Pneumatic MDR30T is a 38 lb compact handheld hydraulic post driver for fence posts, T-posts, ground rods and similar profiles. A trigger lever on the tool controls 2,300 blows per minute at 5 GPM oil flow and 1,1601,450 PSI working pressure, with low vibration for full shifts a light, fast-hitting driver for fence, electrical and erosion-control crews already running hydraulic power.
Open-centre hydraulics let the MDR30T run from a compact hydraulic power pack or a suitably regulated carrier circuit, and a 1 in. rod adapter kit (P/N 3371806057) sets it up for ground rod work. It is the lightest model among the Chicago Pneumatic hydraulic post drivers we carry when posts outgrow it, the rest of our full post driver lineup picks up from there.
