This is the whole kit and caboodle! An entire turn key system for your 5 bbl (or smaller) brewery. Kit consists of the MM-3ProG, Base/Hopper, Gear Motor, Coupler set, Wiring Kit, Gear Motor Base, feeler gauge, and food grade mineral oil. 720lb hour max output with constant feeding will get you brewing for less than the competition. See individual product descriptions for all the details. DO NOT run this mill backwards under any circumstances, you MUST turn the drive shaft ONLY clockwise to feed grain down into the gap. When you purchase our motorized kit the motor will be set up to turn the correct direction.
