Sweep Performance That Keeps Moving Forward

The Brock 3500 Series Commercial Sweep is built to handle heavy loads and push into piles of grain without backing away. This all-electric sweep has the durability and power to keep your commercial grain operation moving forward, no matter what. See the 3500 Series Commercial Sweep video.

Engineering Solutions for Withstanding Heavy Loads

Brock engineers used Finite Element Analysis to test and perfect the 3500 Series Sweep’s design to endure the crushing pressure of grain in bins up to 156 ft. (47.5 m) in diameter. These commercial sweeps are designed to withstand the grain pressures generated in Brock’s largest bins with loads up to 7,000-lb. per sq. ft. (34,236 kg per sq. m).

Forward Motion Auto Drive for True Zero Entry

Brock 3500 Series commercial sweeps are strong enough that they do not have to back out of a pile of grain, even in avalanche conditions. The sweep’s auto drive momentarily stops to clear large amounts of grain, then keeps moving forward without damaging the sweep or requiring bin entry. 

Strong Patented Sweep Arm

  • Brock’s heavy-duty sweep sections are designed to eliminate the need for floor jacks — allowing for absolute zero entry during bin unloading.
  • Exterior bolting flange increases strength while reducing weight.
  • Fewer parts and fasteners translate to faster assembly and cost savings. 

Rugged Drive System

  • Positive sprocket rail drive for no-slip operation and more pushing torque.
  • Auto drive is standard and manages grain avalanches and compacted grain without the need to reverse.
  • Balanced design of sprocket drive ensures smooth operation and continuous engagement with the rail.

Adjustable Bin Wall Agitator

  • Aggressive action breaks up hard-packed fines and soybean pods from the bin wall.
  • Deep agitator paddles propel material to the auger.
  • Adjustable back shield and agitator make it easy to fine-tune the sweep length to the bin’s internal clearance requirements.
