Things to Consider Before Buying a Commercial Weed Eater

Weed can sometimes take a toll on lawns and will require you to get rid of them early enough. Modern weed eaters are designed using the latest technology to give you the versatility you need to reach even those tough corners that are hard to reach. However, investing in a poor quality weed eater can ruin the experience and make it  impossible. In case you are looking forward to maintaining your lawn, here is what to be on the lookout.

Weed Eater Types

Weed eaters are of different types in regards to the power supply option. These include gas and corded electric. Each one has its benefits and challenges.  The electrically powered weed eaters are handy and lightweight. However, the power cord will limit you which requires you to measure the distance. This can be a challenge especially when you are maintaining big lawns.  

Battery powered type offer you better mobility as compared to electric type. Similar to electric weed eaters, battery operated models are lightweight and quiet. Another plus feature which makes battery-powered string trimmers better is their portability. However, you will be required to replace the batteries when they die out. Before working on your next project, it is a good idea to get to know the battery lifespan. This will help you plan and ensure you have enough to get the job done.

Gas trimmers on the other and are a great choice for demanding jobs. Though they may be noisy, and weighty, they deliver enough power to demolish thick and stubborn weeds. One thing that is worth noting is that these trimmers have two varieties of Gas engines. That is the 2-stroke and 4-stroke. The 2-stroke weed eaters offer more power and run on combustion gas and oil. However, they are noisy and may produce polluting smoke. The 4-stroke weed trimmers give less power but are still capable of undertaking bigger commercial projects. They are better choices because of low noise and less emission.



A good weed eater should come with a harness. Even if it does not have one, it should feature fixing points where you can attach a harness. If present, the harness should be as strong and as comfortable as possible. In case you have to buy one, you have two options: buy a purpose made a harness for your brand or an aftermarket option. The purpose made harnesses are costly and high quality. However, you can still find aftermarket harness that is highly affordable but still great in quality.


Weight is one of the overlooked aspects by most people when buying weed eaters. Investing in a heavy weed eater will impact your mobility and ease of transportation. Worse still, using a heavy weed eater to maintain your lawn will drain you faster and reduce your productivity. Regardless of whether you are a home-owner or a commercial landscaper, it is crucial to buy a weed eater that you can manage working and moving around your farm.

Shaft design

Commercial weed eaters can have either a straight or curved shaft. A straight shaft is good in that it allows you to reach out to those hard to reach edges of your lawn. If durability is what you are looking for in a weed eater then straight shafts are the best way to go. People with back problems can also take advantage of weed eaters with straight shafts.

Curved shafts, on the other hand, are comfy, and offer you better control over the device, making them a great pick for demanding projects. However, people with back pains may encounter challenges using them. Though the curved shafts are lightweight, they are not flexible and may break.

Compare the features and choose your preferred design.

Noise and vibration levels

Modern weed eaters are designed using the latest technology to minimize the noise and vibration levels when on use. High noise levels and vibrations can reduce your productivity or impact your hearing.  Consider investing in a quiet model with anti-vibration features.

Powering options

Most gas powered weed eaters feature a starting line. It is possibly most annoying and frustrating aspect of gas engines whether 2-stroke or 4-stroke. Have you been in a situation where you crank the shock but the engine won’t just start? A good way to go around this is to look for the best commercial weed trimmers with a loaded mechanism or sequential start.

A sequential start defines a series of actions you will need to follow in order to start the weed eater. This means you will have to prime and set the choke and then follow a series of two or more steps. There are a few other options, which can provide you with easier and gentler starting than a line. Choose what works for you.

Head Choices

Weed trimmers have two different head types. That is; the bump feed or a fixed-line system. Some people would prefer a bump feed trimmer. With this, you will have to bump the head off the ground to feed more line. As such, the system offers you more control over the line. It is a very simple method to use. The problem is that the spool is prone to damage and the spring worn down over repeated use.

Fixed lines on the other hand use lengths of lines that are already threaded into your trimmer. This type is a popular option for the commercial weed eater. They can use thicker, more durable string compared to bump-feed systems. The only problem is that you will be forced to stop to replace the line each time, which might be cumbersome.

The Cutting Path

It would be great to consider the cutting path. Most regular weed trimmers usually have too small a cutting path to work well on large gardens. If you are looking for the best commercial trimmer then you should consider the cutting path. Note that the size of the cutting path of a weed eater is directly proportional to ease of use and inversely proportional to time and effort.
