Moving Sioux Falls Forward: Diamond Mowers

  • March 30, 2026

Cities and contractors across the country soon could be maintaining their properties with state-of-the-art new equipment developed and manufactured in Sioux Falls.

Diamond Mowers recently introduced the DM360, an all-in-one solution as an industry-leading boom mower and fully featured multifunction machine.

With the signature rotating cab and boom combination, the DM360 gives operators a true 360-degree operational advantage, with improved comfort and clear sightlines to every task.

Advanced features such as joystick steering, all-wheel steer and industry-leading left-hand mowing capabilities expand what operators can do on the job. These innovations simplify roadside mowing, allowing crews to work more efficiently and safely while staying aligned with the flow of traffic, reducing risk and boosting productivity.

“This represents a major leap forward in how municipalities can think about roadside mowing,” said Wayne Baumberger, CEO of Diamond Mowers. “We built the DM360 to solve real challenges our customers face every day: visibility, safety, uptime and versatility. This platform sets a new benchmark for what a dedicated carrier can deliver.”

It’s the latest innovation for a company that has been growing in Sioux Falls for more than 25 years.

“From design and manufacturing roles to corporate leadership and support, it offers exceptional careers and has the potential to grow along with our community.”
