Frequently asked questions

Who is the STIHL MS 151 designed for?

STIHL designates the MS 151 for tree service professionals only, not for general homeowner use. At 2.59 kg with a short 25.4 cm bar, it is a top-handle saw meant to be run one-handed while an arborist works aloft in a tree, rather than a ground saw for felling or firewood.

What engine does the STIHL MS 151 have and how powerful is it?

The STIHL MS 151 is built around a 22.93 cc engine that produces 1.1 kW, or 1.5 hp. That is a small, light powerplant by chainsaw standards, sized to keep the saw manageable one-handed aloft rather than to drive a long bar through thick trunks on the ground.

What bar length does the STIHL MS 151 run?

STIHL recommends a 25.4 cm (10 in) bar for the MS 151. That short reach keeps the saw compact and controllable for precision cuts made one-handed in the canopy, where a longer bar would add weight and reduce the control an arborist needs while working aloft.

What chain pitch does the STIHL MS 151 use?

The STIHL MS 151 runs a 1/4 inch pitch chain, a lighter-duty size than the 3/8 inch chains common on ground saws. Paired with the short 25.4 cm bar, that fine pitch supports the precise, controlled cuts a top-handle saw is expected to make while an arborist works aloft.

How much does the STIHL MS 151 weigh, and why does that matter?

The STIHL MS 151 weighs 2.59 kg without bar and chain, one of the lightest saws in its lineup. That low weight is essential for a saw STIHL designates for tree service professionals, who must hold and maneuver it one-handed for extended periods while working aloft in a tree.

Guides that cover this model

Chainsaw Bar Length Guide: What Size Do You Need? Bar length decides the diameter of wood a chainsaw can cut, but a longer bar is only useful if the engine can pull it. This guide covers the two-cut rule, recommended versus maximum bar length, and the displacement each length needs. Chainsaw Engine Displacement (cc) Explained Displacement is a volume, not a power rating. This guide explains what cc measures, how it relates to kW and HP, why power-to-weight is the better comparison, and what the sub-40cc, 40-50cc, 50-60cc and 60cc-plus bands are for. Chainsaw Weight and Ergonomics: What the Spec Hides Published chainsaw weights leave out the bar, chain, fuel and battery. This guide explains the real in-use weight, how it drives fatigue and safety, and why power-to-weight is the figure worth comparing.
