Grass Trimmers 101

Choosing a grass trimmer, also known as a string trimmer, doesn’t need to be complicated. The main decision lies with whether you want to go with a gas or electric power source. Gas trimmers are more powerful and do the job quicker. Electric trimmers shine when it comes to ease of use, low noise and affordability. Cordless electric trimmers and gas trimmers both offer the convenience of unrestricted mobility. You could also consider an edger to create more definition along your walkways, fences and garden borders. Whatever you decide, you'll soon take your lawn care to a whole new level.

Types of Grass Trimmers


Gas Trimmers

If you have a large lawn in need of serious weed whacking, then a gas-powered trimmer is probably your best bet. Gas trimmers are hands down the most powerful type of trimmer, capable of cutting through large weeds and woody brush. And, since they're not tethered to a fuel source, they also offer more mobility. This makes them a great choice for lawns with lots of flowerbeds and boroughs. Gas trimmers are also durable and easy to operate once you get the hang of them.

Electric Trimmers

For smaller yards, electrical trimmers are a durable option with power to spare. Maintenance is a snap, and they run quietly on their electrical power source. Electric trimmers are also the most affordable trimmer on the market. Simply plug them in and go to work on all those spots your lawn mower doesn't reach. An electrical trimmer is the easy way to keep you lawn well-manicured without letting lawn maintenance take over your summer. When they're not in use, you can store them safely in either your basement or garage.

Cordless Trimmers

Cordless trimmers offer the all advantages of corded electrical trimmers, including low noise and easy storage, with the added convenience of unrestricted mobility. With a cordless trimmer, you can easily get at even the most hard-to-reach spots on your lawn. And the sheer simplicity of the cordless design means you'll work faster and get done earlier, leaving you more time for family, friends, or even other yard work. 

Push Trimmers

When your lawn mower and trimmer both come up short, it's time to pull out the heavy artillery. Push trimmers, also known as wheeled trimmers, have two large wheels and a lawn mower-style handle. Typically gas powered, they're designed for heavy-duty yard work such as tackling thick, woody weeds in roadside ditches.

Grass Trimmer Safety Tips:

• Wear safety goggles, long pants and sturdy, closed-toed work shoes
• Wear hearing protection for all trimmers that emit noise
• Ensure rocks and small animals are out of the path of your trimmer
• Do not operate the trimmer in rain or cut wet or damp grass
• Before use, make sure your trimmer is securely assembled and not damaged
• Always cut away from yourself, never toward yourself

Grass Trimmer Features

Straight Shaft +

The trimmer's shaft transfers power from your trimmer’s motor to its blades. A straight shaft provides longer reach that comes in handy for getting under bushes and shrubs.

Curved Shaft +

A curved shaft is lighter and easier to handle than a straight shaft. This design is best suited for short-range lawn tasks such as precision trimming.

Spilt Shaft +

A spilt-shaft design allows easy conversion of the trimmer to an edger, leaf blower and similar tools.

Rotating Head +

Some trimmers have rotating heads that can be swivelled to a vertical position for edging. It’s great for small areas, but bigger jobs are better tackled with a dedicated edger.

Bump Advance +

A bump advance feeds new line to your trimmer with just a quick bump to the trimmer head. Manual line feeding interrupts your work and usually dirties your hands.

Carry Aid +

Prolonged trimming can tax your back, arm and shoulder muscles. This feature allows you to carry your trimmer easily with the help of a shoulder harness.

Top-Mounted Motor +

Trimmers with top-mounted motors are easier to handle and better balanced. All gas trimmers have top-mounted motors.

Engine Type +

If you’re looking for a quick-start gas trimmer, then you should opt for a four-stroke engine. These models also pollute less than the two-stroke variety, but they do weigh a bit more.

Centrifugal Clutch +

A centrifugal clutch is a nice safety add-on for gas trimmers; it allows the motor to operate without the cutting line spinning.

Starting Aids +

It can be challenging at times to get a gas-powered trimmer started. A spring-assisted starting aid makes that process easier. It especially comes in handy for cold days when your trimmer engine needs time to heat up.

Translucent Fuel Tank +

This allows you to see exactly when your fuel tank is running low. You’ll know when to buy more gas, and are less likely to be stuck with a dead trimmer halfway through a job.
