The all new Workman 250, 350 & 420 MULTIMIXERS are the result of three years of testing and development. As you review these benefits and features we think you will agree the value they deliver to the jobsite is outstanding! Remove the drum in seconds, empty the drum in any position automatically, and rotate the drum without any external gears, now this is progress! All available at a very reasonable cost. The Workman II 250 mixer offers 9 CU FT drum capacity and 6 CU FT batch output. 1.5 HP 110/220v single phase electric motor supplies the power to the direct drive gearbox. This drive system is whisper quiet and is sealed for life.
