Additional Information

Post Equipment Reel Feed Mixers

Post Equipment in Rock Valley, Iowa, sells new and used reel feed mixers from Kuhn Knight, Roto-Mix, Farm-Aid, SAC and all other reel mixer wagons along with feed truck mixers and truck mounted mixers.

What are Reel Feed Mixers?

Reel feed mixers are used to measure, mix and distribute feed to your livestock and it is imperative that you choose the right one. Reel mixers combine augers and reels in a hopper to lift feed and mix it in order to discharge the feed to provide nourishment for your herd. The auger acts as a knife to cut hay and add it to the rest of the feed. There are many options of mixers, but a reel feed mixer can help you maintain just the right ration for the most efficient weight gains of your livestock. Choosing the right option of reel mixer will depend on how much livestock needs to be fed and what ingredients are used in the feed.

Reel Feed Mixers from Post Equipment

At Post Equipment, we check the status of the augers and reels in our reel mixers and are upfront to our customers about their conditions. We even list all the details of our reel mixers, along with their prices, on our website. All reel mixers are available to look at in-person at our Rock Valley location as well.
