The Husqvarna PG 680 RC Floor Grinder and Polisher is a remote‑controlled planetary concrete grinder with Dual Drive Technology and an automated oscillation function, designed for fast, consistent grinding and polishing on medium‑to‑large industrial and commercial floors. With a 27‑inch grinding width and 3‑phase, high‑horsepower motor, it delivers high productivity in both wet and dry applications while still fitting through a standard doorway.

Overview of the Husqvarna PG 680 RC Floor Grinder and Polisher

The PG 680 RC is a remote‑controlled version of Husqvarna’s PG 680 planetary floor grinder, built for concrete floor preparation, repair, and full polishing systems. It combines a compact footprint with powerful grinding pressure, making it suitable for industrial plants, warehouses, retail spaces, and other commercial environments where efficiency and surface quality are critical.

This model is an excellent choice for all stages of concrete floor work, from heavy removal of adhesives and coatings to fine polishing for decorative floors. It is also specifically recommended as a core machine in Husqvarna’s HiPERFLOOR concrete polishing system, which aims to produce durable, high‑gloss, low‑maintenance floors.

Key Features: Remote Control, Oscillation, and Dual Drive

A standout feature of the PG 680 RC is its remote‑control operation, which allows the operator to run the grinder while walking alongside or ahead of the machine. This improves ergonomics by reducing exposure to vibration and sideways forces and lets the operator correct hoses and power cords, move the dust collector, inspect the floor, and prepare the next set of tools while grinding continues.

The automated oscillation function is another unique capability. Oscillation replicates manual grinding movements by making the machine “swing” slightly side‑to‑side, and the operator can adjust the amplitude and frequency to optimize the grinding pattern. This helps eliminate ridges that can form between passes, producing flatter floors and often removing the need for cross‑hatching passes.

Dual Drive Technology provides fully independent control of the planetary head and satellite grinding discs in terms of speed and direction of rotation. This allows precise tuning of aggressiveness and scratch patterns for different tasks, whether aggressive removal or fine polishing.

Technical Specifications

The Husqvarna PG 680 RC Floor Grinder and Polisher has technical specifications geared toward serious professional use. Key specs include:

• Rated input power: about 17.4 hp (13 kW)

• Voltage: 380–480 V, 3‑phase

• Rated current: approximately 23–32 A depending on configuration

• Frequency: 60 Hz for North American models

• Grinding width: 27 in (680 mm)

• Number of grinding discs: 3 satellite discs

• Grinding disc diameter: about 9 in (230 mm) or similar, depending on tooling system used

• Grinding disc speed: 250–1200 rpm (variable)

• Planetary head speed: approximately 5–65 rpm

• Total grinding pressure: about 593 lb (269 kg)

• Machine weight: about 1,097–1,102 lb (498–500 kg), including wheel support

• Typical dimensions: around 50 in height, with a compact length that still fits standard doors

This blend of power, width, and grinding pressure makes the PG 680 RC one of the most productive mid‑size remote‑controlled grinders on the market.

Planetary System, Performance, and Typical Applications

The PG 680 RC uses a planetary grinding system in which three satellite discs rotate on their own axes while the entire planetary head rotates, and Dual Drive lets the operator control these movements independently. This planetary motion produces a very consistent and uniform scratch pattern, which is essential for professional‑grade polishing results and even surface preparation.

The machine is suitable for a wide range of applications, including:

• Removal of adhesives, coatings, and screeds from concrete floors

• Heavy grinding to correct surface imperfections and high spots

• Surface preparation before epoxy, polyurethane, or other industrial coatings

• Full mechanical concrete polishing, from metal‑bond steps to high‑grit resin polishing

• Polishing of natural stone and terrazzo surfaces in some configurations

Because its grinding width is 680 mm, the PG 680 RC fits through standard door openings while still covering significant area per pass, which is useful for commercial interiors and industrial facilities with multiple rooms or corridors.

Productivity, Ergonomics, and Dust Control

Remote control and oscillation together make the PG 680 RC significantly more productive than equivalent manually operated grinders. Operators can maintain optimal grinding parameters over time because the machine can be left to work in a controlled pattern while they prepare the next steps, leading to more effective grinding hours per day.

The machine’s design enhances ergonomics by removing constant physical pushing and reducing direct contact with vibration and lateral forces. An integrated battery allows remote‑controlled transport when the main power is disconnected, simplifying loading, unloading, and moving the grinder around the job site.

In practice, the PG 680 RC is normally paired with a matching industrial dust collection system for dry grinding. Effective dust extraction not only helps meet safety standards but also keeps tools cutting cleanly and the work area visible, which is crucial for consistent results across large floors.

Tooling Options and Integration with Polishing Systems

The PG 680 RC works with Husqvarna’s wide range of diamond tooling, including metal‑bond segments for aggressive stock removal, hybrid and transitional tools for refining scratches, and resin‑bond pads for high‑grit polishing. Bond hardness and grit are selected based on concrete hardness, coating type, and desired finish, allowing the same grinder to handle everything from rough prep to mirror‑like polishes.

This machine is an integral part of Husqvarna’s HiPERFLOOR system, which defines specific tool sequences and process steps to achieve consistent polished concrete in industrial, commercial, or architectural settings. Its ability to maintain consistent parameters regardless of operator changes is particularly valuable on large projects with multiple shifts or crews.
