"It was a really good demo that led me to Rotochopper in the first place so Demo Day is just a springboard to come back and see the people, see what possibilities there are and share stories. Making connections with other people doing similar things and learning from their successes, is what really helps me be successful."

— Tom Gardner, Hay Creek Companies

Our 9th annual Demo Day event hosted customers and prospects from around the world. With over 200 guests in attendance, the demonstrations kicked off with excitement as the B-66 L-Series track and dolly grinder. The event continued with various demonstrations and mini sessions throughout the day, highlighting a variety of use cases and applications of Rotochopper equipment. We thoroughly enjoy the opportunity to offer attendees a behind the scenes glimpse of the facility, equipment and most importantly our dedicated employees. It was a great day full of information, networking and fun; and we are already looking forward to Demo Day 2020!
