9 Best String Trimmer / Weed Wacker (Electric, Gas) 2017 Reviews and Buying Guide

9 Best String Trimmer or Weed Wacker for the Money

One the most challenging aspects for homeowners is the constant battle to keep the garden looking great, maintaining the flowers and vegetables, and keeping the verge and pathways grass-free. And on top of that, we have the horticultural nemesis – the dreaded weed - to keep under control. One thing is for certain, weeds are strong and determined and they can wreak havoc with our gardens and turn our beautiful piece of paradise into a jungle. But instead of having to get down on your hands and knees to wrench out those almost supernatural invasive weeds, a grass or string trimmer can do all the hard work for you.

String Trimmer / Weed Wacker Comparison:​

Our pick


Husqvarna 967055801324L Straight Shaft 4-Stroke Gas String Trimmer

It is a monster trimmer that is especially designed for commercial applications with a heavy-duty engine, but it is surprising lightweight and ideal for medium to large residential properties. It can cut through tough weeds and thick grass, and it has vibration control design for operator comfort, and it is also CARB compliant and there is no need to mix oil and fuel.

3 Types of String Trimmer

There are three main types of string trimmers: electric (corded), battery-powered, and gas-powered.

1. Electric (corded)

Electric line trimmers are the perfect choice for small sized gardens. They are usually more lightweight and quieter than other models and are generally a lot cheaper to maintain than gas or battery-powered trimmers. The downside of electric line trimmers is that they have a limited reach, and you have to be close to a power outlet extension cord. If you have simple gardening tasks like general low maintenance weeding or just trimming the verge, then an electric (corded) trimmer is the perfect choice for you.

2. Battery-powered

If portability and environmentally friendly is what you are looking for, then look no further than a battery powered line trimmer. These portable trimmers can easily take charge of grass or weeds in a small to medium garden. They can fit into the back seat of your car, and they do not require any fuel, and you do not have to worry about tripping over a cord.

The down-side of a battery-powered trimmer is that the battery life will depend on the size of your yard, and you will have to recharge the battery. So, if you have a lot of trimming to do, it is a good idea to purchase a second battery.

Battery powered trimmers are easy on the ears as well. In addition to portability and reduced noise, there are no emissions, and your operational costs are quite low in comparison with electric (corded) or gas-powered models.

3. Gas-powered

A gas-powered line trimmer works well in medium to large sized gardens. They can either be fitted with a two-cycle engine or a four-cycle engine. If your garden resembles a jungle, then a four-cycle engine is the best for you. In comparison to two-cycle engines that require a mix of fuel and engine oil, a four-cycle engine does not require mixed fuel. Gas-powered trimmers are generally more powerful, they are easier to start, and run more smoothly. The downside of gas-powered models is that they are more expensive, and they still emit fumes, and the two-cycle engines can be noisy. Also, some gas-powered models can be labelled CARB compliant.

Another tip for purchasing a gas-powered trimmer is to look for a model that has a transparent fuel tank, so that you can see when you are running low on fuel.

Tips for Choosing the Best String Trimmer for Your Garden

Overall, the great thing about line trimmers is that they can get into places where mowers cannot like: tight corners, around trees, along the edge of a flowerbed, and they can give your garden or pathway a nice and tidy look around the edges or border. For more heavy duty gardening purchasing a trimmer that has brush-cutting capabilities is also a good investment, especially if you have a large garden that has a lot of dense foliage and undergrowth to maintain.

One of the first things to look out for when looking to buy a line trimmer is the shaft of the trimmer. The shaft can either be curved or straight, and they are also detachable line trimmers that come with a choice of cutting tools. You can then use the trimmer as a hedge trimmer, brush-cutter, sweeper, tree pruner, edger or cultivator.

Curved shafts

A trimmer with a curved shaft works best in a small yard. They are shorter, lighter, and are easy to maneuver, so they are ideal for trimming around narrow, small lawns and flowerbeds, and they take up less storage space. They are more ergonomically friendly and can save a lot of strain on your back.

Straight shafts

Straight shafts are best used for large yards or commercial properties. They are sometimes referred to as brush-cutters and they are more heavy-duty and powerful and they also have a longer reach, which makes them ideal tools for more demanding jobs like eradicating dense undergrowth and reaching under bushes and fences.

Cutting diameter

Once again, the cutting diameter will depend on the size of your lawn, garden and the kind of foliage and weeds you need to keep under control. If you have a small to medium garden then a cutting diameter of 10– 14 inches is ideal. If you have a large garden and dense foliage, then choose a line trimmer with a cutting diameter of around 15 – 18 inches. Petrol line trimmers usually have a wider cutting diameter.

Safety guard

The safety guard is located over the cutting head or string. It protects you from flying debris, but some models have larger guards. Having a larger-sized guard can obscure your view.

Shoulder harness

If you have a lot of trimming and cutting to do - use a shoulder harness. Most models do not come with a harness, but if you are using one of the heavier types like a gas-powered trimmer, a shoulder harness will make your job so much easier and will save your back.

Trimmer line

The trimmer line is a nylon or polymer string that cuts through the grass or weeds and comes in two types:

  • A standard-grade line is best for low-intensity trimming in smaller yards, and it is economical.
  • A commercial-grade line is ideal for use in larger yards where there are heavier patches of grass and troublesome weeds.

A handy tip is to keep an extra spool of trimmer line on hand.

Line-feed system

The line-feed system can either be manual, and when you run out of string you will have to turn the trimmer off and then pull or unwind the line out, which is located on a spool. Most trimmers have the "bump feed system" or a 'bump head', where you simply tap the cutting head on the ground and the string will feed out. Some models have an automatic system where the cutting string is sent out when the line gets too short.

Spool type

One of the difficult tasks of using a line trimmer is having to fit a new cutting line onto the spool. Trimmers can come with either a single cutting line or with twin lines. A single cutting line is easier to thread than a twin line, but the twin line can give you a better cut.


Most models have a handle which can make using a trimmer a lot easier, but some also have an adjustable handle that can be rotated. With an adjustable handle you can turn the trimmer over to change from horizontal trimming to vertical edging.


Some trimmers come with just the cutting line and spool and others have additional accessories like brush-cutting blades or extra edging heads.

Safety Tips for Using Your String Trimmer

Just like any other mechanical power tool that you use around the home or garden, a line trimmer can cause serious injury if it is not operated properly. So by practising some safety tips and being trimmer savvy, they can save you and your family from being injured and can help you have a more comfortable trimming experience.

1. Read the instructions or the manual before using your line trimmer. Make sure you use the trimmer as instructed by the manufacturer.
2. Wear eye safety gear to protect you from flying debris and ear plugs to protect your hearing.
3. Wear gloves, sturdy shoes, and long pants to protect your legs.
4. Trimmers are not toys. Children should not use a line trimmer.
5. Be mindful of who or what is around while you are using the trimmer. Do not point the trimmer in the direction of other people or pets and make sure that any bystanders are at least 50 feet away.
6. Do not use a line trimmer if you are using medication or have consumed alcohol.
7. Check the trimmer to make sure it is in good working order. If you are using an electric model, make sure that the cord is not damaged.
8. Before you begin trimming, pick up any loose objects in your working area, like sticks, stones or pieces of metal.
9. If you have a gas-powered trimmer, start the trimmer outside and do not use the trimmer in an enclosed space.
10. Always use the grass trimmer with the cutting head from below the waist.
11. If you need to fix the trimmer and it is an electric modell - make sure it is switched off and unplugged from the power source.
12. Do not use the blower while standing on a ladder or roof, or while up a tree.

These safety tips are based on the safety precautions from the Agriculture and Natural Resources Environmental Health Grass Trimmer Safety Guidelines

  1. I enjoyed your post on string line trimmers. I wasted money on a Kmart electric trimmer then a Sears gas trimmer then I had 2 Roibi gas trimmers then I wised up and invested in Stihl FS 130 stright shaft trimmer it was 36.3 cc it is 2 stroke so you have to add oil to the gas but 2 stroke has a lot more power than 4 stroke it has lots of power to cut through tall grass and weeds. I take the trimmer head off and put on a steel tooth saw blade and cut down brush and small trees up to 3 inch in diameter. This trimmer weighs 13.0 lbs.but with the padded shoulder harness that clips on the trimmer makes operating the trimmer for hours very manageable. The trimmer is very well balanced it was handel bars that makes controling the trimmer very easy. We have the side walk edger attachment they also make a hedge trimmer and pole saw attachment. This trimmer is pricey but is it hands down one of the best investments I have ever made.
