In just 1-3 minutes, the BERG mixer blends all ingredients into a total-mixed ration. Total clean-out is assured with the BERG mixer. Increased milk production, higher butterfat tests, improved herd health, fewer veterinary bills, lower feed costs and savings in labor are some of the results. Quality Design and Construction! Heavy-gauge, totally welded, roller-chain driven, steel drum is one of the unit's few moving parts, with only two grease fittings. No aggressive augers to crush the feed or cause clogging... no dead spots of slotted bolt holes where feed can collect, filter-out or spoil. Continuous, one-way rotation of the drum allows gravity to do the work for loading, unloading and mixing, thereby reducing horsepower requirements (only 3/4 h.p. to 3 h.p. on forage mixers). All BERG Mixers are factory-assembled and tested...ready to operate as soon as the motor and scale are installed. Built in 3 Sizes from 69 to 183 usable cubic feet!
