For a quarter century, Diamond Mowers has built its reputation on one thing: attachments. From its humble beginnings in the roadside mowing space to becoming a powerhouse in forestry mulching and vegetation management, the Sioux Falls, South Dakota company has been the name contractors reach for when they need to clear brush, mow ditches, or masticate entire forests.

But in 2026, Diamond Mowers is making the biggest leap in its history—and the municipal maintenance sector should be paying attention.

The company is introducing the DM360 and DM360X, its first-ever dedicated carrier machines. It’s a bold move that takes Diamond Mowers from attachment manufacturer to full-fledged equipment OEM, and it signals a significant shift in how the company sees its future in the municipal and roadside maintenance markets.

From Attachments to Complete Machines

When Diamond Mowers launched in 2000, the roadside mowing industry looked vastly different. Municipalities and contractors cobbled together solutions—mounting various attachments to tractors, skid steers, and purpose-built carriers from a handful of established manufacturers. Diamond carved out its niche by focusing on the business end of the equation: the mowing heads, mulchers, and cutting implements that actually did the work.

That focus paid dividends. Over the past 25 years, Diamond Mowers has expanded into forestry, land clearing, vegetation management, and dozens of specialized applications. Their attachments can be found on job sites across North America, mounted to everything from compact track loaders to massive forestry carriers.

But somewhere along the way, the company started hearing a consistent message from its customer base. And unlike many manufacturers who pay lip service to customer feedback, Diamond Mowers decided to do something about it.

Voice of the Customer

The DM360 wasn’t born in a vacuum. According to Diamond Mowers CEO Wayne Baumberger, the machine emerged from extensive Voice of Customer (VOC) research—a systematic approach to understanding exactly what end users needed from a municipal maintenance platform.

The feedback was remarkably consistent. Customers wanted a machine that was versatile, productive, and safe. Those three pillars became the foundation of the DM360’s design philosophy.

“We heard from our customers, and took that voice of the customer, and coupled that with our years of industry experience to create this true multi-function machine,” Baumberger explained. “We looked at a number of different things during the design process. We tried to make sure all these things were built in up front, in this platform. The DM360 is really built for the people who run it.”

That operator-centric approach is evident throughout the machine’s design. Rather than adapting an existing platform or simply mounting a cab to a chassis, Diamond Mowers started with a clean sheet—something that’s increasingly rare in an industry where most “new” machines are evolutionary updates to decade-old designs.

The 360-Degree Advantage

The DM360’s name isn’t just marketing speak. The machine’s defining feature is its fully rotational cab and boom system, which allows complete 360-degree visibility and operation.

Here’s what makes this significant: on most boom mowers and municipal maintenance machines, operators work at an angle to the task. Mowing the right side of the road means looking over your shoulder. Switching to the left side means repositioning the entire machine or accepting an awkward operating position that leads to fatigue over a long shift.

The DM360 eliminates this compromise entirely. The cab and boom arm rotate together, keeping the operator perfectly aligned with whatever task they’re performing.

“One of the key attributes here is we have this true 360-degree performance. So, the cab and the boom arm rotate together, and they can spin all the way around,” Baumberger noted. “If you’re mowing on the right-hand side of the road, you can quickly switch to mowing the left-hand side of the road.”

For municipal operators who spend entire shifts mowing ditches, clearing brush along right-of-ways, or performing roadside maintenance, this ergonomic advantage translates directly to reduced operator fatigue and increased productivity.

Specifications and Capabilities

Under the sheet metal, the DM360 packs serious capability. The 11-tonne machine is powered by a 109-horsepower JCB EcoMAX 4.4L engine—a proven powerplant that’s earned a reputation for reliability in demanding applications.

Boom reach options include 7.6-metre and 9.1-metre configurations, giving municipalities flexibility based on their specific right-of-way requirements. The upper hydraulics deliver 117 litres per minute of flow, providing ample power for demanding mowing and mulching heads.

The Q-Connect system and hydraulic quick coupler make attachment changes straightforward—an important consideration for a machine designed as a multi-season work platform. From boom mowing to snow removal, the DM360 is engineered to earn its keep year-round rather than sitting idle when mowing season ends.

Transport between job sites is equally practical. The machine’s 2.5-metre travel width keeps it within standard road limits in most jurisdictions, while the 40 km/h maximum travel speed means operators can move between sites without requiring lowboy transport for shorter distances.

DM360X: More Power, More Versatility

For operations requiring additional capability, Diamond Mowers is simultaneously introducing the DM360X. Weighing in at 11.7 tonnes, the X model adds a 155-litre-per-minute high flow circuit on the lower frame, plus a lift arm with a universal plate adapter and skid steer coupler.

“The DM360X expands the abilities to use this product even further,” Baumberger explained.

That skid steer coupler compatibility is particularly noteworthy. It means municipalities and contractors with existing fleets of skid steer attachments—buckets, forks, grapples, brooms, and more—can immediately put those tools to work on the DM360X platform. Rather than starting from scratch with proprietary attachments, operators can leverage their existing investment.

Safety Built In

Both the DM360 and DM360X reflect Diamond Mowers’ extensive experience in roadside and forestry applications, where debris protection and operator safety are paramount concerns.

Standard equipment includes Level II FOPS (Falling Object Protective Structure) cab guards and 127-mm polycarbonate protection on the front and right side—the areas most likely to encounter flying debris during mowing operations. A rooftop strobe light comes standard for roadside visibility, with beltline LED lights available as an option for operations requiring enhanced conspicuity.

These aren’t afterthought additions. They’re integrated into the machine’s design from the ground up, reflecting Diamond Mowers’ decades of experience building attachments that operate in challenging, debris-heavy environments.

What This Means for the Municipal Market

Diamond Mowers’ entry into the dedicated carrier space is significant for several reasons.

First, it adds a credible new competitor to a market segment that has seen limited innovation in recent years. The major players in boom mowers and municipal maintenance carriers have largely focused on incremental improvements rather than clean-sheet designs. A new entrant with Diamond Mowers’ manufacturing expertise and customer relationships has the potential to shake up a somewhat stagnant market.

Second, the DM360’s emphasis on year-round utilization addresses a chronic pain point for municipal equipment managers. Boom mowers represent substantial capital investments, yet many sit idle for half the year or more. A platform genuinely designed for multi-season duty—with quick attachment changes and versatile hydraulic capability—offers municipalities a path to improved asset utilization and lower total cost of ownership.

Third, Diamond Mowers’ attachment expertise gives it a unique advantage. Most carrier manufacturers design machines first and attachments second. Diamond Mowers has spent 25 years perfecting the tools that actually do the work. Building a carrier around those tools—rather than adapting tools to fit a carrier—could yield meaningful productivity advantages.

CONEXPO 2026 Debut

Both the DM360 and DM360X will make their public debut at CONEXPO-CON/AGG 2026, running March 3-7 at the Las Vegas Convention Center. The show represents the largest gathering of construction and municipal equipment in North America, making it the ideal venue for Diamond Mowers to introduce its expansion into complete machines.

For equipment managers, fleet supervisors, and municipal decision-makers planning their CONEXPO visit, the Diamond Mowers booth should be a priority stop. Beyond the headline DM360 and DM360X machines, expect the company to showcase the full range of attachments designed to maximize the platform’s versatility.

The Bottom Line

Diamond Mowers’ transition from attachment manufacturer to equipment OEM isn’t a casual experiment. The DM360 represents a substantial investment in engineering, manufacturing capability, and market positioning. It’s the kind of move a company makes when it’s confident in its direction and committed to a long-term presence in a new market segment.

For municipal maintenance professionals, that commitment matters. Buying a dedicated carrier is a significant investment, and equipment managers need confidence that parts, service, and support will be available for the machine’s entire service life. Diamond Mowers’ 25-year track record in the industry provides that foundation of confidence.

Whether the DM360 lives up to its promise remains to be seen. But on paper, Diamond Mowers has delivered exactly what its customers asked for: a versatile, productive, and safe municipal maintenance platform designed from the ground up for the people who run it.

That’s the kind of customer-first thinking this industry could use more of.

The DM360 and DM360X will be on display at CONEXPO-CON/AGG 2026, March 3-7, at the Las Vegas Convention Center. Visit Diamond Mowers for more information.
