Walk Behind String Trimmer Features

There are many features you should consider before deciding which walk behind string trimmer is best for your situation. We are providing you with some guidelines below to help you make an informed decision on which trimmer is the best.

Hand-held String Trimmer  Versus Wheeled String Trimmer

A hand-held string trimmer, also known as a weed wacker, is perfect for smaller areas where tall grass is hard to reach with a regular lawn mower. A hand-held trimmer is not practical for large amounts of space, however.

This is where a wheeled string trimmer comes into the picture. Some areas of land are difficult to reach with a lawn mower or lawn tractor. Wheeled trimmers give you more flexibility to cover large, hard to reach spaces. The wheels give you the ability to maneuver across rough terrain and can trim down weeds that are extremely tall.

Engines

Engine size is an important consideration, especially if you need more power to cut through an expansive area of tall weeds and brush. Most walk behind string trimmers have a 4-stroke or 4-cycle engine. They need oil changes and basic maintenance to keep them in good operating condition.

Briggs and Stratton makes an engine they claim requires no oil changes. If you are not a mechanically inclined individual, then you will want to consider an engine that needs little maintenance.

Most wheeled string trimmers have engines that come with a recoil starter that has to be started by a starter rope. This turns the engine over and gets it started. It is best to find a wheeled string trimmer that includes an auto choke feature which eliminates the need to prime the engine ahead of time.

Wheel Size

The wheels on walk behind string trimmers are made of hard plastic or Never Flat material, which means it is not likely you will need to handle a flat tire. Walk behind string trimmers that have larger wheels can maneuver over rougher terrain. For maximum flexibility, you want to find a wheeled string trimmer that has wheels at least 12-inches high.

Handle Grip Bar

When using your walk behind string trimmer, you want to be as comfortable as possible. As you maneuver the trimmer, you may go over potentially rough terrain. Since most walk behind string trimmers have push drive engines, you want the handle grip bar of the trimmer to be at the right height and angle to minimize strain on your back while pushing.

Be sure the trimmer you choose has an adjustable handle height. The handle should also fold down for compactness while you store it and it is not in use..

Finally, you want a wheeled string trimmer that has an anti-vibration feature. This will reduce the tingling in your hands, arms, and shoulders after you have finished using the trimmer.

Cutting Width and Height

Most walk behind string trimmers have a 22-inch wide cutting path. This allows you to cover a large area of grass in a matter of hours instead of days.

You should consider a cut height adjustment feature when choosing a walk behind trimmer. This allows you to adjust the height of the remaining grass or weeds left behind after you trim the area. If you need to leave a few inches of grass or weeds standing after you trim, be sure the trimmer you are interested in buying has an adjusting cut height feature that will accommodate the height you need.

FAQS:

Q: Can I Mow Right After Aeration?

A: Do not mow your lawn right after aeration – stay for about seven days. Also, note where all the pop-ups and sprinklers are to avoid damaging them and water the soil before aeration. 

Q: How Often Should Lawn be Aerated?

A: You should aerate your lawn at least twice per year to ensure that you get a healthy lawn. That is especially important if your yard has thatch buildup and compacted soil.

Q: Why is My Lawn Lumpy?

A:  Even a beautiful, green lawn can turn lumpy or bumpy and uneven. Earthworms, weeds, freezing, and thawing condition can all contribute to this condition.

Set your mower to cut the grass short to find out those bumpy areas with ease. That way, you can make the necessary changes.
