Buyer’s Guide to Getting the Best Cordless Weed Trimmer
Here are a few must-know aspects you must account for while purchasing the best cordless weed trimmer:
How Does A String Cutter Work?
A string trimmer, also called a weed eater, consists of a long, curved or straight shaft with a cutting
head at the end. The cutting head is the part that cuts grass and weeds. A single string or two strings can move fast enough to create a blade-like effect that cuts off the growth.
This tool helps in reaching weeds in tight spaces where a lawnmower (check out this round-up of the best lawn mowers available in the market) will not fit, such as around flower beds or other landscape features. Since most weed trimmers can easily be converted to an edge trimmer, you can use them to create clean edges around your lawn.
What Should Be Considered When Choosing a Cordless Weed Trimmer?
When buying a string trimmer, you should consider the size of the garden, how often you will use the tool, and who will be using it. Also, keep in mind the:
Trim Width or Swath Width
The swath width tells us how wide the path that the trimmer cuts through weeds in one pass is. Models on the market today have varying stripe widths from 10 to 18 inches. If you want a wider swath width, you will have to buy a trimmer with greater power. Although, since powerful trimmers require larger batteries, they will likely be heavier.
Types of Batteries
Most trimmers need an immense amount of power to work, that’s why they use lithium-ion (Li-on) batteries. But, there are a few machines that use NiCad batteries too.
Even though lithium batteries are more powerful, NiCad batteries are cheaper (an average of $ 70 to $ 125 less). Two other advantages of lithium batteries are that they are also smaller and last longer on a single charge.
NiCad batteries suffer from a “memory effect”. To elaborate, if the battery is used before it is fully charged, or if it is charged before the power is used up, the charge status is saved. Further on, it will be kept restricted in the future. Remember, if you do opt for a trimmer with a NiCad rechargeable battery, you should let it fully charge before use and fully discharge before charging.
Considering everything, a Li-On battery line cutter is the best option for most users.
Battery Operating Power or Voltage
You should take into account the voltage or the operating power of the battery, in addition to the battery type. The average power of today’s string cutter batteries is around 18 to 60 volts.
On the high end, more powerful batteries are used and can cost $200 or more per battery. The string trimmers in this category are often sold without a battery and charger, both of which must be purchased separately.
Lower-end batteries are suitable for powering many line trimmers, and a battery or two is often included with the purchase of a trimmer.
Usage
Cordless trimmers are easier to use than gas trimmers, as no fuel has to be mixed and no time and energy are wasted in pulling a cord. In addition to that, a few other factors determine how easy it is to use.
Auto Feed vs. Pump Feed vs. Button Feed: This refers to how the tool releases an extra cut line if it breaks during use. Standby is the area where the user can bump the trimmer on the ground to get a few extra inches of line. Some newer models have an automatic feed sensor that measures the length of the thread and releases more if necessary.
Others, however, have a push button that automatically releases more lines. Auto and button feeds eliminate the need to hit the roll, which can reduce the risk of damage by hitting too hard. Still, many commercial cutters do use bump feed because it is more comfortable to maneuver.
Curved Shaft vs. Straight Shaft: Few stringers have a shaft that runs from the trimmer head to the end, while other models have a different shaft curve.
The operation of curved-shaft trimmers is easier since the spool is already at a convenient angle for cutting weeds. On the contrary, straight trimmers can even accommodate interchangeable tools, like a tree trimmer head that can be changed depending on what you are cutting.
The straight trimmers are best for users who are at least 6 feet tall, while smaller users will appreciate the curved shaft trimmers.
Noise
Cordless string trimmers have a huge advantage over gas trimmers in terms of noise pollution.
Gas trimmers emit an average of 90 decibels, or roughly the same volume as a motorcycle when it passes at a distance of 25 feet away. In contrast, a cordless thread cutter emits around 77 decibels, which is comparable to the volume of music in the living room.
Advantages and Disadvantages of Battery-Operated String Trimmers
Similar to all devices and tools, even a battery-operated trimmer has its advantages and disadvantages.
Advantages:
- Doesn’t release emissions
- Lesser noise
- Not too heavy
- Easier to use than gas models
- Doesn’t need too much care
- More movable than wired electric models
Disadvantages:
- Not as powerful as gas trimmers
- More costly as compared to gasoline and wired electric model
- Limited battery life, typically 15-30 minutes
- New batteries required every two to three years
All in all, battery-operated grass trimmers are more suitable for small yards than large yards due to their operation time constraints. They are also suitable for lawns without thick grass and overgrown weeds, due to lack of power.
Conclusion
The best way to keep your lawn tidy is by using string trimmers. These machines help in ensuring you can reach the tighter spots, hence giving your yard a proper shape. All gardening enthusiasts should add at least one best cordless weed trimmer from this list to their gardening tools collection.
