An 86cc saw that ships on a 28-inch bar for $1,540 is aimed at a specific buyer: someone felling big timber often enough to need the bar, but not running a saw hard enough to justify the 592 XP. The odd part of the spec sheet is the weight — at 16.5 lb the 585 is actually two tenths heavier than the 92.7cc 592 XP above it, because the XP gets the lighter magnesium-intensive build. So the 585 is the heavier, less powerful, cheaper saw of the pair, and the $140 gap between them is small enough that anyone genuinely working in big wood should price both. Where the 585 earns its place is as a second saw or a landowner's big saw: X-Torq fuel economy, a 36-inch bar rating, and heavy .063 H83 chain standard, without flagship money. It is not a limbing saw and it is not trying to be.

Best for: Landowners and part-time fallers who need a big-bore saw and a 28-inch bar without stepping up to the 592 XP.

Manufacturer figures except the engine class and single-pass cut, which are derived here. What each spec means

86cc on a 28-in bar
Rated to 36 inches
Heavy .063 H83 chain standard

Where it is strong

86cc and 6.9 hp with a 28-inch bar and chain included at $1,540
Rated to a 36-inch bar, enough for most hardwood felling in North America
Heavy .063 H83 chain standard — more durable in dirty wood than narrower gauges
X-Torq engine keeps fuel burn reasonable for the displacement
Three chain gauge options so the saw can be set up light for bucking or heavy for felling

Where it falls short

At 16.5 lb it is heavier than the more powerful 592 XP — the XP has the lighter build
Only $140 separates it from the 592 XP, which makes the value case awkward
16.5 lb powerhead plus a 28-inch bar is a two-hands-and-a-break saw, not a limbing tool
No AutoTune at this price, where the XP flagships get electronic management
