The Husqvarna PG 680 Floor Grinders & Polishing Machine is a 27‑inch planetary concrete grinder built for industrial and commercial floor preparation, repair, and full mechanical polishing in both wet and dry applications. With Dual Drive Technology and, in the RC version, remote control and automated oscillation, it delivers high productivity, flatter floors, and consistent finishes across medium‑to‑large concrete surfaces.

What Is the Husqvarna PG 680 Floor Grinders & Polishing Machine?

The Husqvarna PG 680 is a planetary floor grinder in the 680 mm (27 in) class, designed for demanding concrete surface preparation and polishing work. It is widely used on industrial floors, warehouses, retail spaces, and commercial projects where access through standard doors is required but high output is still essential.

The machine is available as a standard walk‑behind model and as the PG 680 RC (remote controlled), which adds automated oscillation and remote operation for even higher productivity and better ergonomics. Both versions are excellent choices for concrete floor preparation, coating removal, and polished concrete systems such as Husqvarna’s HiPERFLOOR.

Key Features and Dual Drive Technology

A defining feature of the PG 680 family is Husqvarna’s Dual Drive Technology, which provides fully independent control of the planetary head and the satellite grinding discs. The operator can adjust speed and direction of both the discs and the planetary head separately, optimizing the machine for heavy removal, fine grinding, or polishing.

This flexibility allows aggressive cutting patterns for coating and screed removal, then smoother, overlapping scratch patterns for polishing by simply changing speeds and directions, rather than switching to a different grinder. Parameter settings make it possible to dial in consistent performance for specific applications and then repeat those settings across operators and shifts.

On the RC model, remote control operation means the operator is not constantly exposed to vibration and lateral forces and can correct hoses, move the dust collector, and prepare the next tools while the machine is grinding. This significantly increases effective grinding hours per day on large jobs.

Technical Specifications

Exact specs vary slightly by configuration, but core technical details for the PG 680/PG 680 RC include:

• Power input: about 17.4 hp (13 kW)

• Voltage: 380–480 V, 3‑phase

• Rated current: around 23–32 A depending on model and market

• Frequency: typically 60 Hz for North American units

• Grinding width: 27 in (680 mm)

• Number of satellite discs: 3

• Grinding disc speed: approx. 250–1,100 rpm (variable)

• Planetary head speed: approx. 5–65 rpm

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

• Weight (including wheel support): about 1,097 lb (498 kg)

These specifications place the PG 680 among the most powerful and efficient grinders in its size class, with a balance of maneuverability and production rate.

Planetary System, Oscillation (RC), and Performance

The PG 680 uses a planetary grinding system: three satellite discs rotate on their own axes while the main planetary head turns, creating a uniform and controllable scratch pattern on the floor. Dual Drive Technology on top of that planetary action gives fine control over aggressiveness and pattern, which is critical for high‑end polished concrete.

The PG 680 RC adds an automated oscillation feature that mimics manual side‑to‑side grinding movements. By adjusting oscillation amplitude and frequency, the operator can achieve the best possible grinding pattern and eliminate ridges that otherwise form between straight passes. Oscillation often lets the grinder cover the floor in one pass instead of cross‑hatching, saving time and producing flatter floors.

In real‑world use, the planetary system, oscillation, and Dual Drive combine to deliver high removal rates during prep and very consistent gloss levels during polishing. The grinder is suitable for both wet and dry work, depending on tooling and dust or slurry control setup.

Applications: Grinding, Preparation, and Polishing

The Husqvarna PG 680 Floor Grinders & Polishing Machine is designed for a broad set of applications on concrete and some natural stone/terrazzo surfaces.

Typical uses include:

• Removing adhesives, coatings, and screeds from concrete floors

• Heavy grinding and flattening of uneven slabs and high spots

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

• Full mechanical polished concrete systems (such as HiPERFLOOR) from metal‑bond steps to high‑grit resin polishing

• Polishing of natural stone and terrazzo surfaces according to Husqvarna guidance

Because its 27‑inch width still fits through standard doors, the PG 680 works well in commercial interiors such as retail stores, schools, hospitals, and office buildings, as well as industrial plants and warehouses.

Productivity, Ergonomics, and Dust Control

Compared to manually pushed grinders, the PG 680 RC offers significantly higher productivity thanks to remote operation and the ability to maintain optimal grinding parameters over longer periods. One operator can keep the machine working while simultaneously preparing the next step (changing tools, applying GM 3000 grout, tending the dust extractor), increasing daily output.

Ergonomics are improved because the operator is not constantly pushing against the machine or exposed directly to its vibrations and sideways forces. Transport to and from the job site is easier as well: an integrated battery allows remote‑controlled maneuvering even when the main power supply is disconnected.

The PG 680 is typically paired with industrial dust collectors for dry grinding and with slurry vacuums when grinding wet, especially in systems like HiPERFLOOR. Good dust and slurry management not only supports health and safety compliance but also helps diamonds cut more efficiently and improves visibility of the surface.

Tooling and Integration With Polishing Systems

Husqvarna offers a complete tooling range for the PG 680, including metal‑bond diamond segments for aggressive stock removal, transitional/hybrid tools for refining scratches, and resin‑bond pads for finishing. Bond hardness and grit are chosen based on concrete hardness, existing coatings, and the desired finish level.

The PG 680 is a central machine in the HiPERFLOOR concrete polishing system, which specifies step‑by‑step sequences of Husqvarna tools and chemicals to produce predictable, durable polished concrete finishes. Its ability to hold stable parameters and repeatable motion patterns makes it well suited for large projects where consistency across thousands of square feet is critical.
