Self-propelled operation
The powered drive moves the grinder through the pass while you steer. Less manual pushing and pulling helps reduce operator fatigue, especially across repeated grinding and polishing passes.

Self-propelled planetary grinder
Let the grinder do more of the moving. Our HTG 680SP Pro combines self-propelled travel with a wide planetary grinding path for productive concrete preparation and polishing. The powered drive reduces the effort of pushing and pulling the machine, helping you work with less fatigue and maintain steady passes while you guide the grinder.
Keep it for 7 days. Pay the equivalent of 4 daily rentals.

Controlled travel helps you maintain a consistent pass pattern. Pair the planetary grinding system with suitable diamonds and an appropriate working speed for efficient removal and uniform surface preparation.
The approximately 27-inch grinding path covers more floor per pass than the 550 Pro. Combined with self-propelled movement, it is a practical choice for open floors, coating removal, concrete preparation and polishing.
Add suitable diamond tooling for preparation or polishing pads for your finishing sequence. Tell us about the floor and your target finish; we will confirm the tooling and its rental price with your request.
