PG530 specifications

The Husqvarna PG530 is a powerful and versatile floor grinding machine designed for professional contractors and heavy-duty applications. This equipment is ideal for preparing and finishing various types of surfaces, including concrete, terrazzo, and natural stone. Built with advanced technologies and rugged construction, the PG530 stands out in the market for its reliability and performance.

One of the key features of the Husqvarna PG530 is its unique three-disc design, which provides efficient grinding performance. The three grinding heads allow for better distribution of weight and improved balance, ensuring an even grind across the floor.

This adaptability makes the PG530 suitable for a wide range of applications, from light surface preparation to heavy-duty grinding and polishing.

Additionally, the PG530 is equipped with Husqvarna's patented Dual Drive Technology. This innovative system provides independent speed control for both the grinding heads and the machine's forward movement. This capability allows operators to adjust the speed of the grinding discs while controlling the speed of the machine itself, resulting in enhanced flexibility and control during operation.

The machine is designed with user comfort in mind. Its ergonomic handle and adjustable working height make it easy to operate for extended periods without causing fatigue. The PG530 is also fitted with an integrated dust collection system, helping to maintain a clean working environment by minimizing dust and debris. This feature is essential for safety and compliance with health regulations.

In terms of usability, the PG530 is easy to transport and set up, making it a practical choice for contractors on the go. Its compact footprint ensures that it can maneuver in tight spaces, while the folding handle allows for easy storage.

Overall, the Husqvarna PG530 combines powerful performance, innovative technology, and user-friendly design to meet the demands of flooring professionals. Whether for surface preparation, grinding, or polishing, the PG530 is a reliable tool that enhances productivity and delivers superior results.
