Wacker Neuson has updated its 1.2-ton tandem vibratory roller line with improved visibility, curb clearance and easier service access.
The RD12 roller series was originally developed and introduced to the North American market 30 years ago.
The popular ride-on rollers are ideal for residential and commercial construction for asphalt and subbase soil compaction of parking lots, driveways, secondary roads and trails. As well, the rollers are an ideal choice for landscape and golf course contractors to statically roll sod, fairways and greens.
Wacker Neuson’s RD12 rollers are the fifth-generation compact rollers designed and manufactured at the company’s Menomonee Falls, Wisconsin facility.
The new series was unveiled during a press conference at World of Concrete 2019 in Las Vegas.
“We’re really proud of this roller,” said John Dotto, a product marketing manager with Wacker Neuson. “Every time they come out with a new version, I say ‘wow, it’s just the best thing.’ We took a roller that was a little archaic 30 years ago, and we just stormed the market with the first articulated 1.2-ton roller.”
The RD12 vibratory roller series is available with either a gasoline or diesel engine. Both units provide the same 88 cm drum size, and front drum dynamic centrifugal force of 1,542 kg that has become the industry standard for rollers in this class. The RD12A is powered by a 20.8 hp Honda gasoline engine, while the RD12K is equipped with a 21.6 hp Kubota diesel engine.
Voice of customer
Wacker Neuson engineers consulted with end users and dealers in voice of customer sessions during the redesign process for the new RD12. Many of the new features and benefits are a result of those discussions.
The redesigned machine now includes fully recessed hydraulic motors to improve curb and side clearance, allowing easy compaction near curbs, walls and in confined areas.
As well, a tapered frame and hood design improves visibility to the drum edges and provides a more comfortable operation.
Increased water and fuel capacity minimizes the need to refill during the working day, which in turn improves jobsite efficiency.
An ergonomically designed operator’s platform provides comfort and efficiency. Both water and vibration functions are integrated into the joystick control for less hand movement. Furthermore, fuel and water gauges are conveniently located for quick fluid level checks during operation.
“There’s great improvements on this thing. The ergonomics of the dash, a new designed platform and a new watering system,” Dotto said.
A unique hood design and pivoting floor plate provide for improve service and maintenance access. Quick, tool-free and spacious access to engine, hydraulic and water systems contribute to lower total cost of ownership.

The roller is also equipped with a smaller hydraulic tank.
“If you look at other rollers this size, you have a large 10-gallon hydraulic tank on there,” Dotto said. “Through technology and proper oil cooling, you can get away with smaller tanks, less hydraulic oil, less discharge and replacement, and be more environmentally friendly.”
Additional features include four-point tie downs and lift points for easy transport; pressurized water system with eight-position timer, cup holder, steering wheel with steering assist knob, intuitive display and convenient armrest locations for operator comfort.
The rollers continue to feature dual drum drive and articulated steering that provides excellent maneuverability and compaction results. As well, onboard telematics are an additional option for the rollers.
“For the contractor that has this in their fleet and wants to keep track of it maintenance-wise and where it’s located, onboard telematics is an option,” Dotto said. “And it’s a nice feature to have on here.”
