Summary:
only the best

Strengths:
best machine ever used absolutely unreal!

Weaknesses:
none

Summary:
Overkill for grass but as a brushcutter, nothing is safe from it!

Strengths:
POWER! reliability, build quality, adjustments,starts easily and did I mention power? Replaced a brand new Husqavarna which at one time was a great product but mine was *#@&.

Weaknesses:
Fairly loud, somewhat heavy but not a problem.

Summary:
The Best on the market!

Strengths:
power,does not bogg down in tal grass, can keep up with any speed you choose to go at!

Weaknesses:
none!

Summary:
Good balance of power and weight. Has many different head attachments. Full reccomendation on this one. If you don't buy a gas powered Stihl trimmer, you might as well order one from Fischer Price.

Strengths:
The Stihl FS250 is a powerhouse. It doesn't bog down and has minimal drag through even the heaviest brush. It will even mow down small saplings with only standard line. I work for a Parks Department and use one every day. Keep it greased, replace the air filter perodically and run decent fuel through it and it will tough it out for years to come, as with any Stihl product. Fantastic weedeater.

Weaknesses:
If you're not careful you can really kill line with this beast. If you get too close to a fence or a T-bar and don't react quickly, kiss your line goodbye. That's easily remedied by skill and precision however. With experience it is the perfect machine.

Summary:
The best trimmer/brushcutter I've ever used - better even than my old school FS 86 that lasted the better part of two decades. All power, with little fatigue. This is the next best thing to spending $800 on a bulky, heavy, although very powerful 300 or 400 series cutter.

Strengths:
The power of this machine is unreal. I've not ever not been impressed with this trimmer (and don't really understand why it's classified as a trimmer - Although I have no trouble using it to trim residential areas, this thing oughtta bear the "brushcutter" title.) I can go from trimming around mowed areas, directly to chopping up tall grass and hay without worrying that I won't have the right tool. ALSO, this machine seems like it might even be lighter than my trusty FS 90. This might just be my expectations playing tricks, but I couldn't tell a difference.

Weaknesses:
Gets hot. As a tall fella, I only use one hand to trim over hills and hard to reach places - it's just easier (thankfully the 250 is light.) I usually grip the handle tight and brace the top of the motor housing at my mid-forearm. This method is even effective with the 250, but if you touch the wrong part of the housing, prepare to scream and smell burnt hair.

Summary:
A-1 They just dont make a better trimmer

Strengths:
power power power

Weaknesses:
none
