Pros & cons

Stihl MS 170

  • Real Stihl build and dealer network at a $219.99 price that undercuts most big-box homeowner saws
  • 8.6 lb powerhead is light enough for overhead limbing and long cleanup sessions without fatigue
  • 3/8" Picco low-profile chain is cheap to replace and easy to sharpen for beginners
  • IntelliCarb compensating carburetor keeps it running as the air filter dirties
  • Massive verified track record — 4.5 stars over 4,401 Ace Hardware reviews
  • Sips fuel; a tank goes a long way in yard-duty use
  • Underpowered for firewood — owners report it bogs and slogs in logs over ~12 inches
  • No side-access chain tensioner; adjusting the chain means loosening bar nuts the old way
  • Anti-vibration system is minimal compared to the MS 250 and up, so hands buzz on longer cuts
  • Clamshell engine and plastic-heavy construction aren't built for rebuilds or hard hours
  • Newer MS 172 successor is already on stihlusa.com, so the 170's days look numbered

Husqvarna 120 Mark III

  • One of the cheapest routes into a dealer-supported gas saw
  • Light and neutral-balanced — comfortable for limbing sessions
  • X-Torq engine sips fuel compared to older small saws
  • Sold and serviced everywhere: Lowe's, Tractor Supply, and dealers
  • Mark III revision now runs bars up to 18 inches
  • Cold-start pull count is the recurring owner complaint
  • Plasticky build next to Husqvarna's own 435 II
  • Tool-required chain tensioning feels dated at this price
  • Shares value-tier internals with Poulan — the badge is the upgrade
  • Underpowered for regular bucking of hardwood
