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
