Why Choose a String Trimmer

There are several features that can narrow your search for a string trimmer.  Those include the type of trimmer engine, shaft and cutting head you prefer to use.

2-Cycle vs. 4-Cycle

2-cycle string trimmers deliver plenty of power for cutting through tall grass and weeds.  They require oil and gas to be mixed together for fuel.  If you don't mind mixing oil into the fuel, 2-cycle string trimmers are a good choice.

4-cycle string trimmers have more powerful and efficient engines that slice through tall, thick grass and weeds with ease.  4-cycle engines also eliminate the need to mix oil and gas - they take straight fuel.  This makes 4-cycle engines an excellent choice for any yard.

Straight Shaft vs. Curved Shaft Trimmers

Straight shaft string trimmers have a longer, straight boom that makes it easier to trim under bushes and other hard-to-reach places.  This makes them ideal for yards with a lot of shrubs, bushes and ditches.

Curved shaft trimmers are more ergonomic and comfortable to use for longer periods of time.  These are best for yards that are larger and mostly flat.  They are also ideal for trimming around flower beds, sidewalks and other open areas.

Trimmer Cutting Heads
