The PG 690 is a versatile and powerful floor grinder but still compact enough to pass through a standard door (total width: 26 in / 67 cm). This is the go-to-choice for most grinding jobs, both industrial and commercial, and for users that prefer a non-motorised drive. The planetary drive system and the improved, Husqvarna-unique Dual Drive Technology™ deliver excellent grinding performance. Adjustable weights for extra grinding pressure and LED lights are optional. Suitable for all applications: floor prep, grinding and polishing. A good choice for the HiPERFLOOR® concrete polishing system. To maximise reliability and reduce maintenance, the vital components of the PG 690 are protected against dust and slurry inside the hermetically sealed grinding head and electrical cabinet.
