Stihl FS 240 Trimmer Review – Is It Any Good?

Stihl claims that this bike-handle trimmer is ideal for tackling challenging cutting locations. Stihl also claims that this model is able to take care of anything from highway exits to low-lying ditches.

Stihl FS 240 Key Features

STIHL ErgoStart (FT)

STIHL ErgoStart technology conveniently minimized the effort required to start the tool. We managed to get the machine started by a simple pull of the started cord at normal force.

IntelliCarb™ Compensating Carburetor

This intelligent Carburetor automatically measures and adjusts the air pressure, which helps to keep the RPM at a consistent level regardless of any blockages.

How Does It Perform?

In our experience, the FS 240 is an excellent tool and packs a punch of power when it comes to performance.

In combining a heavy-duty design with the necessary versatility, we were able to handle a variety of challenging landscaping/clearing situations.

Because this machine provides 6% more power and 20% more fuel efficiency, we were able to spend more time cutting instead of refueling.

How Loud Is It?

As with any heavy-duty trimmer, you’d definitely want to wear earplugs to block most of the decibels radiating from this powerful brush cutter. Sounds specs were collected below:

Is It Easy To Handle & Perform?

With the bike-handle design and attaching harnesses, this brush cutter is easy to handle and use for the purposes intended.

What’s the Blade Like?

Various blades can be used in conjunction with this machine. The Wood Cut Circular saw blade, for example, is a special steel tool that is effectively used for gnarled bushes and tree trunks that aren’t too thick.

Another one of our favorite blades was the Brush blade. Made of special steel, we found this blade to be ideal for clearing tough patched of grass and challenging hedges.

How Is The Power Source / Engine?

With Stihl’s special Ergo Start technology, the effort required to start the tool is halved, with the starter cord being easy to pull. With that said, this cutter requires a mixture of 2 stroke oil and petrol at a 50:1 ratio.

What Attachments Are Available With It?

ADVANCE Universal Harness

The soft padding on this harness definitely makes work more comfortable.

STIHL shoulder strap

The STIHL shoulder strap with soft padding makes work much more comfortable.

ADVANCE forestry harness

The advance forestry harness from Stihl offers extra freedom of movement. The ergonomic design for forestry applications involving circular saw blades is light and comfortably worn.
