Best Commercial String Trimmer

Once you have mowed the lawn, it’s time to manicure it. If you’re a professional landscaper, doing so is easier when you have the best commercial string trimmer at hand. A commercial string trimmer is also ideal for homeowners who need to trim the grass around many flowerbeds, walkways, and fences.

But when it comes to choosing the best, things get confusing.

Here's a list of Best Commercial String Trimmer

 The market is full of options, and deciding which specific model best suits your needs is hard.

You must decide which technology you want, what make, and above all, how much you want to spend. We know deciding this is hard, that’s why we’ve put together this list of the best commercial string trimmers on the market.

Before revealing it, though, let’s see what to look for before buying.

How to Choose a Commercial String Trimmer

Picking a commercial string trimmer seems daunting, but you actually only need to pick the right tool based on the features highlighted in this list.

1. Power

Commercial string trimmers have long been associated with gas engines. However, the advancement of technologies brought many alternatives. Today, you can still buy a gas-powered weed eater, but cordless battery-powered units also bring sufficient grit to deal with most types of vegetation.

The main decision, therefore, is deciding whether you want unlimited runtime or environmental friendliness.

Know that some manufacturers sell their units with battery kits containing two or more batteries, for added convenience.

2. Shaft

Another thing to consider is whether you want to use the same shaft (thus engine) on more than one tool. This could come as a cost-effective solution if you also need to buy hedge trimmers or pole saws.

Some commercial string trimmers have a removable shaft compatible with an array of other bare tools from the same range.

3. Swath

Most commercial string trimmers have a cutting swath above 12 inches, but the actual size determines how fast you can finish your chore. It also determines whether or not the string trimmer will fit into a tighter spot.

For the best compromise between velocity and convenience, we recommend a string trimmer with a swath of around 13 inches.

4. Maneuverability

 Perhaps the most important feature is the maneuverability. A commercial string trimmer is supposed to be used for extended periods, so it must be lightweight, well balanced, and adjustable in height.

Gas string trimmers are heavier than cordless ones.  In terms of maneuverability, pick a unit with height adjustable shaft and pivoting handle.

Soft grip is another important thing to check, as it improves overall maneuverability.

5. Price

Lastly, another important thing is the price. Commercial string trimmers cost definitely more than their residential counterparts; we recommend to set a budget and stick to it. If you’re not sure what’s a good price for a string trimmer, check out our options below.

All commercial string trimmer in our list brings unrivaled value for money and are designed to withstand even the most demanding tasks. Check them out.
