Brock looked at all the details to get every bit of performance and durability possible out of the 1500 Series Power Sweeps. Some might question,  “it’s just a sweep, how much innovation can it have?” At Brock, we looked at all the details to get every bit of performance and durability possible out of our 1500 Series Power Sweeps. We started with the gearboxes to make sure they can stand up to the rigors of tough use. Then we added several patented designs and other improvements that make a big difference in your daily operations.
