Center Well

Redesigned center well uses fewer components, and unload tube bolts directly onto the center well for easier installation. Extended bolts on center well gate break up clusters. Steel roller bearings allow for smooth gate operation and durability.

Rack-and-pinion controls are standard on all direct gear drive sweeps. Simplified sweep engagement with a band on control handle, with pin for locking position. Separate control pipes for center and intermediate wells along with a crank handle make opening and closing gates very easy.

End-wheel design features a fluted tread to help draw in grain from the edge of the bin to the auger. A wider tread profile helps to reduce load on flashing.


One size does not fit all when it comes to unloading grain, and that’s why GSI has a full line of bin unloads. With the ability to move 1,500-5,000 bushels per hour, powered from outside the bin, a direct gear drive sweep can be an efficient unload option for you.
