The Osborne RF3-Series Big Wheel Feeder provides fresh feed on demand for finishing pigs. Patented mechanical-flow feed delivery means pigs’ interaction with the feeder – not gravity – determines feed flow. This original Osborne-engineered design improves feed-to-gain ratios while almost completely eliminating waste. The round, self-cleaning trough provides pigs with a less stressful eating experience and 360-degree access to feed.

Big Wheel Feeders are manufactured with abrasion-resistant, reinforced fiberglass hoppers and troughs and standard painted steel metal parts. Feeders also available with combination galvanized/zinc-plated or combination painted/304 stainless steel metal parts. Contact Osborne for combination feeders. Shipped knocked-down on a pallet with complete assembly and operating instructions. Assembled feeders available by special order. Hopper lids are available for all models for outdoor use.

Frequently Asked Questions

  1. What does mechanical feed flow mean and how does it reduce waste?
    The signature feature of Osborne’s Big Wheel Feeder design is its mechanical-flow feed delivery system. This means animals – not gravity – dispense the feed they need, and no more, which drastically reduces waste. Traditional feeders typically rely on gravity for feed to transfer from the feed hopper to the trough area. This design requires lots of manual adjustments as pigs grow and lots of overfilled troughs and waste. Big Wheel Feeders eliminate gravity flow by design. A unique system of parts inside the feed hopper stop gravity flow and requires animals to dispense the feed they need ad libitum. Overloading waste is eliminated by preventing feed dispensing when the trough is full.
  2. How do I teach pigs to use the “Big Wheel”?
    Animals quickly learn through play that the feed wheel in the trough area has to be rotated or moved back and forth for feed to dispense from the hopper. Big Wheel Feeder users typically fill the trough manually when first introducing animals to the feeder. As the first trough full is eaten, the pigs naturally begin playing and interacting with the wheel and quickly discover it helps in directing the feed to the outer trough area where it can be more easily consumed.
  3. Can I use my Big Wheel Feeder outside?
    Yes. Most Big Wheel Feeder models work well outside – even when exposed to the elements – and plugging is rarely a problem. When the feeder is stocked with an adequate number of animals, water from rain or snow rarely overcomes the self-cleaning action of the feed wheel. Additionally, the position of the feed hopper in relation to the trough, accompanied by the Big Wheel’s mechanical-flow design, prevents moisture from “wicking up” and causing plugging issues. For feeders stocked with only a few animals, drilling a few weeping holes in the trough aides in moisture reduction before it can cause plugging problems.
  4. How does the round trough design of Big Wheel Feeders compare to rectangular feeders?
    Rectangular feeders force pigs into close contact with one another. The round design of the Big Wheel Feeder spreads pigs radially around the trough, providing more standing-room space and less physical contact. Less physical contact means less wasteful competition. Linear trough space can never be fully used with rectangular feeders, and the Big Wheel’s round design occupies less space than comparable rectangular feeders. Big Wheel Feeders may also be installed in the center of a pen or in the fenceline to use one feeder to feed two separate groups.
