Customer Testimonials

John Silva, J.S. Dairy - Delta, Utah

I wanted to tell you how satisfied I am with your Lucknow feedbox.  I purchased the 2290 model and am pleased with its performance.  The low sides make loading easy and fast.  The speed in which it mixes the feed is amazing.  By the time the last ingredient goes into the mix the load is ready to be fed to the cows.

Evergreen Holsteins - Ethel, Ontario

They are very well built and competitive machines compared to the other makes out there.  The difference is that if service is needed on our LuckNow mixer, we are going to get it right away.  The other manufacturers won’t do that.  We are very happy with our LuckNow mixer.
