Criteria To Examine In String Trimmers
String trimmers, which cut greenery with whirling plastic lines, can trim right around trees, steps, and rocks. They're perfect for maintaining a neat edge along walks and beds, and they also can tidy a rocky hillside that's too irregular to mow. Many could also accept metallic blade for leveling tough scrub and small saplings.
The correct choice depends on the property's size, its terrain, and your tolerance for noise and pollution. Bear in mind: Trimmer tips spin at near 400 mph, so don't forget eye and ear protection, as well as boots, long pants, and gloves. And stay clear of outdoor wiring, lest you zap yourself rather than weeds.
Gas or electric?
Gas hedge trimmers are generally preferred for large properties and extended use, and they still do the best job of whacking away thick underbrush. However, gas engines require more care and maintenance -- and don't ignore makers' warnings regarding fuel storage and ethanol content in fuel -- the process can bring about a costly repair that won't be covered under warranty.
Cordless Electric String Trimmers
Because they're battery-powered, cordless trimmers don't require that you worry about gas or perhaps oil. In addition they don't need an extension cord that may restrict your mobility.
Different features like the form of the shaft or the cutting style will help you select the right string trimmer. However, the big draw of cordless string trimmers is the power supply.
New battery technologies have made cordless weed whackers popular than ever before. The truth is, some have plenty of battery life to end a similar jobs that a gas trimmer can.
Types of Batteries
You'll find 2 types of rechargeable batteries readily available for your lawn tools:
Lithium-ion batteries
Ni-Cad batteries
Lithium-ion batteries have become the regular, but both types provide power for the yardwork tasks. However, if you'll work on large projects, look at a backup battery which means you won't have to wait for one battery to recharge in case you run out or power before you're done.
And keep in mind that the battery only drains when you're squeezing the trigger. Only run the trimmer when you're trimming, and the battery lasts even longer.
Lithium-Ion Batteries
Lithium-ion batteries are the more modern innovation to power string trimmers. Made for improved performance, lithium-ion batteries are extremely popular for three reasons:
1. They're lightweight - up to 50% lighter than the usual comparable Ni-Cad battery - and so the string trimmer won’t weigh all the if in use.
2. They don't experience any drop-off in power or performance because the battery runs down. Power output stays consistent through the entire cycle of use.
3. They may be recharged up to three times as many times being a Ni-Cad battery prior to the battery must be replaced.
Lithium-ion batteries are available in many different voltages, which range from 18 volts to 82 volts. Check your trimmer's product manual to figure out simply how much voltage you will need when purchasing a replacement lithium-ion battery
Ni-Cad Batteries
Ni-Cad batteries are still available, but they represent an older method of battery technology. They're relatively heavy, and you may visit a noticeable drop-off in power and gratifaction as being a Ni-Cad battery runs right down to the end of the charge.
In past times, Ni-Cad batteries are already more affordable than their high-performance lithium-ion counterparts. However, they're becoming less available, which means that you'll have several more many years of trimming before you when you purchase a lithium-ion trimmer when considering time for you to upgrade.
Varieties of Trimmer Shafts
In the same way you'll find two types of batteries accessible for your cordless string trimmers, you'll also find string trimmer shafts in just two different styles, such as more widespread in comparison to the other:
Straight shaft string trimmers
Curved shaft string trimmers
Straight shaft string trimmers will be the more widespread type. They work efficiently under fences and in hard-to-reach corners or another tight spaces.
Many straight shaft models include a telescoping shaft, which lets you make your shaft as short or long as you have to work comfortably.
Curved shaft string trimmers are less common from the cordless string trimmer category. The curved design will make it hard to reach small corners, but it does make these trimmers great for grass and weed trimming in open areas.
What the best string trimmers have
Very light. Users bear the complete weight of this tool, so it's crucial that you pick a string trimmer that's comfortable to transport and maneuver around your landscaping. Shoulder straps are accessible for some models to aid get rid of the burden through your arms.
Ample safety guards. The shield at the bottom of the string trimmer protects users from flying debris. Although a highly-designed guard blocks most things, it's always better to wear safety goggles, closed shoes and pants to safeguard against airborne grass and rocks.
A trigger lock. In order to avoid accidentally running the trim head when not in use, the best string trimmers utilize a trigger or throttle lock. This switch needs to be inside a convenient location and easy to use.
Quiet motors or engines. Generally, electric (corded and cordless) string trimmers are quieter than gas-powered models, but noise levels vary in each class. Typically -- and particularly with gas trimmers -- wearing ear protection is recommended.
Powerful trimming capabilities. If you have to take down unruly weeds and tall grass, search for a string trimmer that's provided with dual nylon lines. Lines which can be .08 inch or thicker cut through tougher vegetation -- but make sure to follow makers' recommendations regarding cutting lines as using one that's heavier duty than your trimmer is rated to deal with could damage the motor.
An edging option and clean finish. Some string trimmers possess a swivel head that rotates on the ideal edging position. Others expect you to turn the full tool. In any case, the string trimmer should stay nicely balanced at any angle, providing you with good visibility of your area you're trimming by leaving a crisp edge.
Low vibration. Gas engines are notorious for vibrating, which could fatigue both hands leaving them numb. String trimmers with anti-vibration technology will be more comfortable to utilize over extended periods.
Good balance. The string trimmer should remain at the right angle with no fight; normally, this is easiest using a top-mount motor. The most effective string trimmers have shafts that change lengths or moveable loop handles that enable you to adjust the tool to match your height.
Easy-to-use feed and reload features. Reviewers don't possess a preference between bump-feed and automatic-feed systems, given that the string trimmer delivers the line smoothly when needed. The most effective string trimmers possess a spool that's an easy task to load with new line.
Durable construction. The best string trimmers incorporate high-quality materials into a thoughtful design to make pull-cords, switches, spools and engines that could withstand many years of use. Even expensive models may have some plastic, which keeps the extra weight down. But a longer warranty isn't an assurance of the better tool; many owners report problems getting warranty service through some brands.
