Our U-Trough Direct Gear Drive Sweep features a permanently installed integrated sweep and unload to allow for the control of the complete unload system by a single motor from outside the bin. No heavy sweep and motor to carry in and out of the bin, making your day-to-day safer and easier. U-Trough’s fit under a standard 12” GSI Floor.

Higher Capacity

U shape allows for higher capacity unloading under most standard aeration floors. Design also reduces the chance of grain damage as compared to round tubes.

Drive Wheel

Patent-pending drive wheel sweeps grain from the bin wall as it propels the unloader, providing aggressive sweep action, even in tough conditions.

Easy to Use

GSI U-Troughs offer an easy to use design. The gearbox shifter engages the sweep from the outside of the bins, while standard rack and pinion gate controls are on all unloaders, making opening and closing gates easier.

Incline Elbow at Discharge

An inclined elbow elevates the discharge to a fixed angle with a 20” (508 mm) life from center discharge-to-ground to accommodate your needs to fit other items under your powerhead.


Sweep Drive Options

Gearbox sweep drive features an enclosed shifting mechanism with no chains in the gearbox. One motor drives the unload and sweep from outside the bin. An extra long center gate is designed for maximum grain flow.


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 5,000 - 7,500 bushels per hour, our U-Trough can be an efficient unload option for you.
