Husqvarna 440 vs Stihl MS 251 Wood Boss
Tinted cells mark the better figure on that row alone: more engine, longer bar, lighter, cheaper. A lighter weight is only a win on the same basis.
What owners like and complain about
Husqvarna 440
- 9.78 lb powerhead is the lightest rear-handle gas saw in Husqvarna's current US range
- X-Torq engine uses noticeably less fuel than older two-strokes of the same displacement
- Smart Start reduces pull resistance enough that most owners start it one-handed on the stand
- Side-mounted chain tensioner, no need to hunt for a scrench mid-cut
- .325/.050 H30 chain is stocked by every Husqvarna dealer and most hardware stores
- $400 street price undercuts the 445S by $50 while saving nearly a pound and a half
- Carburetor complaints dominate owner reports — hard starts and an idle that will not settle are the recurring pattern
- 18-inch bar is the rated maximum, so there is zero room to step up
- 40.9cc bogs in anything much over a 12-inch hardwood round
- Long-term reviewers frequently recommend spending up to the 455 Rancher instead
- No heated handles or AutoTune at a price where some competitors offer tool-less tensioning
Stihl MS 251 Wood Boss
- 2.2 kW and a .325"/.063" chain — proper firewood gearing, not a narrow-kerf homeowner chain
- 10.6 lb powerhead is light for 45cc; owners report full days without arm fatigue
- Long-term owners in firewood forums report multi-year service on filters and plugs alone
- 20% better fuel economy and about half the emissions of the MS 250 generation it replaces
- $430 is roughly a third of what a pro 50cc Stihl costs
- Plastic clamshell engine against the MS 261's magnesium crankcase — it will not take long, dirty workdays the same way
- Owners report it drops revs and can die under sustained load in softwood
- Factory bar and chain are the weak point: dulls and burns quickly when pushed
- Scattered reports of piston failure in the first weeks with warranty claims denied
- No M-Tronic — altitude and seasonal changes mean carburetor tinkering
