2023 Loftness 12-Foot System Bag Unloader GBU 12

With the capacity to load a 1,000-bushel trailer in about 5 minutes, the Loftness GL System 12 Grain Bag Unloader (GBU 12) outperforms anything on the market, not only in speed, but also in simplicity of use, ruggedness and reliability. Stable site-to-site transportation, fast setup, easy operation and straightforward maintenance make it an indispensable part of any grain bag storage strategy.

Features may include:

• Built around abrasion resistant 1/4-inch steel flighting, the main auger is supported by two 7/16-inch bearings. Like all GBU 12 augers, they are computer balanced and factory tuned for the highest possible performance. The main auger and auger tube is hinged for transport and storage.

• Foldable for storage, the main auger is controlled through the use of a hydraulic cylinder. The main auger hinge point is precise and robust, precision welded and self centered. Self-aligning top bearings ensure that the auger shafts align and that the male-female drive couplers engage every time.

• The 12-inch augers feed material to the discharge auger. Two hydraulic motors deliver power to drive material to the center of the bag.

• The main hydraulic system holds 70 gallons of hydraulic fluid. It includes a return filtration system to reduce wear and also a cold-weather bypass.

• At the core of the hydraulic system rests the inline hydraulic pump configuration. Each pump is dedicated to an individual task: cross-feed augers, the main discharge auger, and system cooling and accessories.

• The GBU 12 cooling system has proven itself under the most adverse heat conditions. The reason: a hydraulically driven oil fan cooler. The cooling system also features automatic bypass based on pressure.

• A highly successful and proven design from Loftness, the bag roller is 19.5 feet wide and capped on either end with 23-inch discs to ensure the empty bag stays on track. Welded teeth spaced along the entire roller shaft ensure that the leading edge of the bag is captured securely and squarely. The system features a high-torque, hydraulically driven and controlled design.

• The entire roller drive assembly was designed to provide the power and torque needed for the 12-foot bag unloading process. Hydraulic motor power is increased, and speed is reduced through a dual-width chain, triple reduction drive system. The massive power of the roller drive system pulls the tractor and unloader into the grain.

• Operator can simply disengage the roller drive by hand and the bag can then be rolled off the bag roller tube. No tools required.

• The multifunction controls offer easy ground level access, and precisely regulate the bag roller speed, adjust the axle height and retract or extend the hinged main auger.

• Different grain and seed types differ in weight, thus changing the shape of the bag. The knife can be positioned to match any bag shape.

• An adjustable axle with mechanical stops provides consistent height of cross augers.

• A heavy-duty axle with electric brakes for over road reliability. Quickly raises the machine for transport to the next site.
