Fast, Simple Grain Bag Unloading & Recycling

At RENN we understand that loading the grain bag is only part of the story – unloading and recycling the empty grain bag are also crucial steps in the process.

RENN has responded to the needs of farmers by drawing on decades of manufacturing experience to design and build Grain Bag Unloaders that are easy to use and offer exceptional plastic management.

RENN Grain Bag Unloaders can unload 9', 10', and 12' diameter bags with minimal power requirement.

As the bag is lifted and pulled onto the drive spools, it is gently guided into place by the RENN roller and hold down system – reducing stress on the bag and helping prevent spillage. RENN's continuous-flow unloading system effortlessly draws the Unloader and power unit into the bag, while quickly unloading the bag contents through high-capacity discharge augers.

The RENN Onboard Recycle-Ready Plastic Management System uses RENN’s unique hydraulic ratchet system to wind the spent bag onto rear rewind spools, keeping the plastic clean for recycling. Once unloading is complete, the plastic is rewound into a recycle-ready package, which slides easily off the collapsible rewind spool. Operators appreciate the time savings and simplicity of this grain bag windup system. The RGU 1218 CD Grain Bag Unloader has been designed to carry and process an entire 12’ x 500’ grain bag.

Switching from transport to operating mode is a simple task requiring minimum effort and no tools; the operator just backs into the grain bag and lowers the machine. 

Designed and built to operate in Western Canada’s harshest field and weather conditions, RENN Unloaders allow farmers to empty a grain bag anywhere, at any time, efficiently and with minimal effort.
