Description
The Osborne RO85-Series Big Wheel Bulk Finishing Feeder provides fresh feed on demand for finishing pigs and hogs. The patented mechanical-flow feed delivery means pigs’ interaction with the feeder – not gravity – determines feed flow. The mechanical-flow design is intended to minimize feed waste by letting pigs dispense feed on demand. The round, self-cleaning trough provides pigs with a less stressful eating experience and 360-degree access to feed. Wet weather and stocking levels can affect feed flow. Inspect the feeder regularly and follow the manufacturer's operating instructions.
Big Wheel Feeders are manufactured with reinforced fiberglass hoppers and troughs and hot-dipped galvanized steel parts. The feeder ships on a pallet and is unassembled to help keep shipping costs down.

Why Use A Large Capacity Hog Feeder
The following is a fictional farmer account illustrating potential uses of a large-capacity hog feeder. It is not a customer testimonial or a guarantee of results.
As a hog farmer with a bustling operation, my days are filled with the rhythmic routine of tending to my beloved swine. Each morning, as the sun begins its ascent over the horizon, I make my way to the heart of our farmyard, where our pride and joy—our pigs—await their daily sustenance. And at the center of it all stands our trusted companion: the large 85-bushel outdoor hog feeder.
From the moment we introduced this behemoth feeder into our operation, our lives were transformed. No longer were we burdened with the constant worry of refilling feed troughs multiple times a day. With its immense capacity, the feeder became a reliable source of nourishment for our growing herd of swine, ensuring that food was always available whenever they needed it.
But the advantages of this feeder extend far beyond its sheer size. The innovative design of the Osborne self-cleaning trough paddle sweep proved to be a game-changer for us. Gone were the days of manually scrubbing troughs to remove stubborn residue and debris. Instead, the integrated paddle sweep effortlessly cleaned the trough with each rotation, maintaining a pristine feeding environment for our pigs.
Not only did this design save us precious time and labor, but it also minimized the risk of disease transmission among our animals. A clean feeding environment meant healthier pigs and reduced veterinary costs—a win-win situation for both our farm and our beloved swine.
With the Osborne outdoor hog feeder standing tall in our farmyard, we've been able to focus our attention on other aspects of our operation, confident in the knowledge that our pigs are well-fed and cared for. It's more than just a feeder—it's a symbol of efficiency, innovation, and the unwavering dedication we have to our animals and our craft. And for that, we're endlessly grateful.
