Husqvarna PG 400 Gas | Single-Disc Floor Grinder

Husqvarna PG 400 Gas | Single-Disc Floor Grinder

HUSQVARNA CONSTRUCTION SKU: 970704601 Copied!

Is this the right tool for the job?

Best For:

  • Sidewalks, ramps, slabs: trip hazards, joints, paint/cure-seal cleanup
  • 1–2 person crews doing daily outdoor prep with a matched dust vac
  • Multi-site work where gas power beats long cords and weak circuits

Not Ideal For:

  • Indoor or occupied spaces—gas exhaust and fumes; use electric instead
  • Thick elastomeric coatings or heavy mastic—use scarifier/blaster
  • Large open floors needing high production—use a planetary grinder

Why Pros choose this tool:

  • Gas engine—no cords or generators → self-contained power → keep remote sidewalk prep moving all day
  • Single-disc with matched diamonds → uniform, bond-ready CSP → coatings and overlays stick, fewer callbacks
  • Compact single-disc head → precise grinding in tight areas → avoid over-cutting and reduce hand work
