Ultimate Weed Eater Buying Guide 2016
1. What is a weed eater and why should I buy it?
A weed eater, alternatively known as a ‘weed-whacker’ or ‘string trimmer’, is an instrument constituting a flexible monofilament line (rather than a blade) for cutting a variety of areas including grass that are inaccessible by mower, thick weeds, and yard detailing. The tool is comprised of a long shaft with a cutting head towards the end, along with one or more handles. Some of the best weed eater models even come with a shoulder strap, blade guard, and other additional comfort features.
Houston, Texas based George Ballas invented this instrument in the early 1970s. He came up with the idea when he watched the rotating movement of cleaning brushes in an automatic car wash. Weed trimmers are generally used to maintain yards and sidewalks, keeping them well trimmed and free from any kind of weeds along the edges. Those who suffer from back problems or face difficulty in bending over can comfortably eliminate weeds by using this equipment. Weed eaters also speed up a previously tedious job so that you can finish your entire yard in less than half an hour!
2. Types of Weed Eater
Weed eaters mainly come in three categories: cordless, corded electric, and gas. Each type has its own features as well as pros and cons.
2.1 Cordless weed eaters
In almost all cordless trimmers, the motor is powered by a rechargeable lithium-ion battery. This is perhaps the best weed eater if you do not want to produce much pollution. The head rotates, enabling the weed eater to edge and trim at multiple angles and provides increased accuracy. Some of the most efficient trimmers, according to weed eater reviews, are fitted with an automatic system that enables one to get more string as required, without stopping the work that is in progress or having to bump the head. Some models come with a low-grip handle which reduces fatigue during the work by offering a comfortable grip.
- No need for connection to a power outlet; you can even use it during a power outage
- Battery-powered trimmers are virtually noiseless.
- They are lightweight and can be carried anywhere around the yard with ease
- Cutting power is usually a little lower to make up for the amount of electricity available
- Batteries require charging and occasional replacement, possibly adding extra time or money to the job
- Cordless string trimmers are good for small yards, but they are not well suited to heavy duty jobs
On the whole, the cordless variety is good when you need portability and are intending to use it for a small-medium yard. There is no tension of carrying a cord or finding a power source. Since it is quite lightweight, women and children can also easily carry it and use it for quick cutting jobs without touching weeds or grasses.
2.2 Corded Electric Weed Eaters
The corded or electric weed trimmer provides the right balance between weight and power. These weed eaters do not use gas or oil; instead, they draw electrical power through a cord you must plug into an outlet. They are environmentally friendly, as they do not produce exhaust emissions. Since these are plug-in weed eaters, you get maximum power to tackle heavy weeds and grasses, as well as overgrowth. The corded models can come with adjustable height, PowerDrive transmissions, as well as the provision of conversion from trimmer to edger and vice-versa.
- They do not use gas and oil, causing minimal pollution to the atmosphere
- Lighter than gas or battery powered units
- Quieter than gas weed eaters
- Since this variety comes with a cord, you won't run out of power mid-way through working
- The price is quite affordable because the equipment does not require expensive batteries or fuel.
- Cutting & Pruning can take longer for big projects, as the power level is lower than in a gas weed eater
- Movement is restricted by length and reach of the cord
- Not effective for commercial use, as power supplies can be unreliable
If you have a good and consistent power source, the corded electric trimmer is a good choice as it leads to considerably less pollution than a gas trimmer and is more powerful than its cordless counterparts. It is also efficient and adjustable, so if you have a small to medium lawn with heavy growth, this is an ideal type for you. It can be conveniently used by women, children, and the elderly as this is the lightest weight type of weed eater.
2.3 Gas Weed Eater
Gas weed eaters do not require any electricity. You just need to fill the tank with gas or a mixture of oil and gas, based on which model you are using. The engine size allows the unit to turn 2 mm of line, and certain models make use of nylon blades in combination with the reel. A majority of gas motors possess displacement between 21 cc and 32 cc. In short, they are the power horses of the string trimmers.
- Capable of holding more string at once, giving a wider range for cuts
- Highest cutting power of all weed eater types
- Since these weed eaters are not limited by any kind of power cord, they are able to reach difficult areas such as the far edge of a garden or a field
- Great for commercial use
- It releases a considerable amount of air pollutants into the atmosphere, which often becomes a grave regulatory issue in certain states (2-stroke engines are worse than 4-stroke)
- These are the heaviest type of weed eaters
- The amount of vibration makes them noisier than other string trimmers.
* A discussion on 2-stroke and 4-stroke weed eaters
There are two styles of gas weed trimmer engines: two-stroke and four-stroke. From power output to maneuverability, each has its own advantages and disadvantages, as is also evident from the string trimmer reviews.
Two-stroke trimmers call for a combination of oil and fuel (gasoline) at typical ratios of 1:50 or 1:40. In the case of four-stroke trimmers, mixing of oil and gas is not required. You just need to fill the oil tank and fuel tank with four-stroke oil and gas respectively. Four-stroke string trimmers are quieter and more efficient than their two-stroke counterparts.
More power is packed within a smaller engine in the case of two-stroke trimmers. Compared to four-stroke trimmers of the same size, more horsepower at higher revolutions per minute can be produced by the two-stroke engines. Moreover the two-stroke models are lighter. Their higher ratio of power to weight enables them to trim through thick growth with no significant decrease in engine power.
Four-stroke trimmers have more weight than two-stroke trimmers. This heavy weight can be an issue for some users who prefer maneuverability and ease-of-use while using trimmers. If you want a lighter machine, opt for the two-stroke trimmer.
Since four-stroke trimmers involve bigger engines with more components, the price is slightly on the higher side. So, if you have a budget constraint, it is better to go for a two-stroke product.
3. Curved and Straight Shaft
The performance of the weed eater is affected by the design of the shaft, to a certain extent. All the shapes do not show equivalent performance; however, there is a unique purpose behind each design. It is good for buyers to go through string trimmer reviews as well as understand the benefits and the drawbacks prior to selecting a particular design.
- Straight shaft string trimmers
This design is noteworthy for the length of reach offered, which is very useful when you are dealing with tight spots or underbrush. For tall people this length is helpful; however, for those with short height the equipment may prove to be cumbersome. Use this model when you want to trim weeds and grasses behind trees or underneath decks.
- Curved shaft string trimmers
Weed eaters which come with a curved shaft provide greater control compared to straight shaft trimmers. Compared to straight trimmers, they are also lightweight, and the majority have additional features. For instance, in the curved shaft electric or gas models you can easily find low vibration features. The curved shaft offers a comfortable way of trimming out unwanted growth from regions surrounding posts and fences, which can be difficult to remove otherwise.
4. How to Choose the best string trimmer for Your Need
Now you have a good working knowledge of weed eaters, let’s wrap things up clearly and briefly.
Different people have different needs and budgets. Here is some basic advice:
- My budget is less than $100 :
Choose an electric weed eater. You can get plenty of good ones for your money. This all-round workhorse is perfect for the home and the limitations only really affect commercial users rather than the casual cutter.
- My budget is from $100-$200:
This price point allows you to comfortably step up to a battery-operated version. Quiet and highly eco-friendly, you might be restricted in terms of running time but for a home user prizing portability, buying a string trimmer that runs on battery power is a wise choice.
- I can spend more than $200
If you have a little more to spend then a gas-powered weed eater is probably your best bet. This variety is equally good in your own garden or for business use. The added cutting power comes at the cost of weight but if you want to reach awkward places and don’t mind a bit of noise then gas is the way to go.
- Special requirements:
- I find it difficult to manage heavy equipment
Whether you are advancing in years, a female garden enthusiast or for any reason uncomfortable with bulky tools, focus on weight as a priority. Don’t make the mistake of being seduced by the power of a gas-powered weed eater. They are heavy and bulky. Choose electric or cordless models and you can enjoy the convenience of this handy piece of kit without the backache!
- Loud equipment bothers my neighbors: help!
Respecting our neighbors is important. If you want to trim your garden without kicking out a great deal of noise then again sidestep weed eaters which are fuelled by gas. They have many advantages but are also extremely noisy. With cordless or electric trimmers you can enjoy a well-trimmed garden without bothering the people around you: win-win!
- My yard is very small
If you will be cutting a limited area then electric or cordless models are the best fit. Reduced cutting power and the need for recharging will not be an issue with a smaller space and you will gain by having equipment which is quiet and ultra-light.
- I regularly cut large areas of grass and want to use my weed eater commercially
If this is the case, opt for a gas model. With no cord you can freely cut away over big sections of grass and you’ll enjoy a better range of cuts as well. Gas trimmers might be a little heavier and slightly noisy but with proper safety equipment a gas weed eater will give you the power and durability you need for working in these conditions.
In general, it is not possible to point out a single product as the best weed eater. It completely depends on you and your lawn or yard. When you are familiar with the differences between the various products and the best use for each, shopping becomes all the more convenient. Remember that the marketplace has a string trimmer to suit everyone’s needs!
