Once you have your lawn cut the job of getting the lawn to look perfect is to tackle any unruly stray grass around the edges and any obstacles, the solution in most cases will be a string trimmer to get that perfect lawn look you are after.

The string trimmers come in three different power options we will cover all of them below to help you get the best match for your type of garden it also may be worth pointing out that some people call them to weed whackers.

String Trimmer Power Types

First, we must cover the main thing that you will come across and that the power types each have their benefits and negatives and one may suit you better than the next person the thing to do is see how we describe and list there pros and cons below and then see which one matches the closest to your needs.

Mains Electric String Trimmer

These are generally the cheaper option on the market that need plugging into your mains electric, they are designed for light tasks only like cutting your grass edges and around obstacles.

With all power tools that have an electric cord, you have to bear in mind the size of your garden to see if you can get to the furthest part with the cable.

They do weight much lighter than all the other types of trimmers witch is great if you have a big area to cover, keep in mind the cable length.

Pros
  • Lightweight
  • Easy to use
  • Quiet
  • Low Maintenance
Cons
  • Less Power
  • Small cutting swath
  • Limited reach with cord
  • Can’t handle brush

So we recommend these if you have a small to medium size garden that only requires small tasks like edging your grass and other obstacles, you can read our Top 3 Mains Electric string Trimmer Picks Here if however, you will be taking on bigger jobs you may need a different powerpoint.

Battery String Trimmer

The battery string trimmer normally takes a little jump in price from a corded trimmer as you are paying for the convenience of not trapping around a cord, and this alone will be a price worth paying.

So just like the cord strimmer, they don’t pack as much as a punch as let’s say an oil trimmer but they will be perfect for someone who has a small to the large garden that only needs to edge around there grass.

It’s worth saying even though you don’t have to trap the cord around with you and that gives you a much greater reach the battery does come with its disadvantages, I’m sure you will be able to guess the main one run time, models will run for 30/60 minutes so if you need it longer you will need extra batteries.

Also on the battery front if you have some other power tools that are battery operated and it’s the same brand it may be worth checking if they are compatible as this may just save you buying extra.

Pros
  • Big Reach – no cable
  • Lightweight
  • Easy to use
  • Quiet
  • Low Maintenance
Cons
  • Extra batteries
  • Small cutting swath
  • Less Power
  • Limited reach with cord
  • Can’t handle brush

So there we have it that should cover the pros and cons of a battery string trimmer and give you a good idea on what there ideal use is, we recommend them for people with any size garden that will only be tackling light tasks see our Best Battery String Trimmer Picks Here if this isn’t your ideal fit then we recommend looking at the next power option gas.

Gas String Trimmer

Last but not least of the power options and it’s the most powerful one the gas-powered string trimmer, These are the powerhouse of string trimmers and what you want if you have a big job on your hands.

These are designed for cutting large areas of long heavy brush, they are generally much heavier than all the other power types as you are lugging around a petrol engine. They’re great for big jobs but don’t tend to lend themselves to well to little jobs like lawn edging as they can be two powerful but there are two power options below that may help here.

Two-Cycle Engine is a little less powerful and maybe the best of both worlds, they will edge your lawn if you go easy and will be able to tackle brush.

Four-Cycle Engine is the most powerful model and if you are tackling a garden jungle then this will cope just fine, they are quieter than the two-cycle engine and run cleaner.

Pros
  • large cutting swath
  • Can tackle big brush
Cons
  • HeavyMore focus on big tasks

So there you have gas string trimmers covered and separate power options that gas has we find that gas string trimmers are more suited to people who have larger gardens and regularly tackle long brush. Here is our Top 3 Gas String Trimmer Picks Here

Type of String Trimmers

There are three different types of string trimmers, well we say that but there is what we all think of when thinking to string trimmer long pole with a string that spins on the end (putting it crudely).

The second type is a brush string trimmer they are just like our crude description that we used above but are much sturdier build and have a thicker line to tackle thick brush.

Then you can get a walk behind string trimmer, these are not normally used in domestic gardens and are more suited for anyone that needs to cover a very large area of thick brush.

String Trimmer Features

Extra features are not always needed but can at times make getting your job done quicker and easier and we will cover them below to help you decide if the feature is something that you want or you are happy if you don’t get it.

String Trimmer Rotating head

A rotating head is just that a rotating head that allows you to rotate the head vertically to tackle grass edges and up against walls.

String Trimmer Wheel

This is a basic addition that can be useful, the wheel supports the weight of the trimmer and allows you to push your trimmer along giving your arms a rest.

String Trimmer Telescopic shaft

This will allow you to move the shaft to best suit you’re your height.

String Trimmer Head Angle

Some trimmers will allow you to angle the head so you can get under garden furniture this one is a little gimmicky.

String Trimmer Handles

Some mainly gas will come with double handles this will allow you to swing your trimmer in an arc getting the job done quicker.

String Trimmer Loop Handle

Corded and Battery will more likely have this type of handle it will allow you to hold your trimmer from different angles; they also come on gas trimmers.

String Trimmer Harness

Mostly on gas-powered trimmers the harness will reduce the strain on by taking the weight off your arms.

Line, blade and line-feed systems

Grass string trimmers will come with one of the following cutting systems line, blade or line-feed system

Line and line-feed systems

Trimmer line feed system will break if it hits anything hard and not wrap around creating a mess, it will wear down after some time of trimming and break off, you will then need to feed out more line here are the different feed styles.

Bump Feed

You simple bump the trimmer head on the ground and it will push out extra line.

Automatic Feed

When you start your trimmer line will auto-feed out giving you a new length.

Manual Feed

The user stops the trimmer and has to manual pull out the line.

With all the different feed systems it’s important to remember to regular feed some line out so it doesn’t get to sort and go back into the head, this is not a disaster but is a pain to take the head off and feed it again.

Some trimmers will have double string these are great and get the job done quicker but the downfall with them is that it’s a little trickier if you do need to feed more line.

Trimmer String to replace is not very expensive I would always by an extra spool when you buy your trimmer and when you run out to buy another this way you will never run out.

Blade Trimmer

Blade Trimmers don’t have to worry about feeding line, lose a blade and you simply clip a new one back on and you’re ready to go.

The problem with blade trimmers is that there not made to tackle anything big and people may find trimming to close to the floor will lose you a blade.

The blades are also a lot more expensive than a string so this is something to bear in mind when making your choice.

Brush Trimmer

For brush trimmers, they can come with a head that has a string and then you remove the head and replace the string with a metal plate to tackle brush.
