[ vertical mixer ]
At Haybuster, we put 40 years of hay and feed processing experience into our Cutter-Mixer-Feeders (CMFs). Our engineers with farm and cattle backgrounds designed them with input from dairy and beef growers throughout North America. Haybuster products are built with attention to durability, versatility and reliability. Compare our equipment to our competition and you will see the difference. Our CMFs are built heavier and stronger for long service life.
