Customers sometimes ask us what top beaters or shredder bars are used for on manure spreaders. They are designed to break up and shred clumps of pen-packed manure in order to help the spreader’s main beater put out a more even spread pattern. Actually, our Conestoga single-beater design with its rooster-comb paddles will spread most pen-packed material just as well as or even better than competitive spreaders equipped with shredder bars. So, why pay for all the added weight and probable maintenance costs of a shredder bar? But what about customers who work frequently in really heavy pen-packed material and request a solution? Conestoga offers for them a top beater as an option.
