Your Guide to Choosing the Best Walk-Behind String Mower

Walk-behind string mowers, also called string trimmers on wheels or string trimmer mowers, are super handy tools for tackling overgrown grass and weeds. They’re perfect for areas where a regular lawnmower can’t go, like steep slopes, around obstacles, or in thick, tall weeds. Let’s find the right one for you!

What to Look For: Key Features

Power Source

String mowers come in two main types: electric and gas-powered.

  • Electric: These are usually lighter and easier to start. They can be corded or battery-powered. Battery models offer freedom from cords, but you’ll need to manage charging times. Corded models give you unlimited run time as long as you have power.
  • Gas: Gas-powered mowers are often more powerful and can handle tougher jobs. They don’t need to be plugged in, giving you more mobility. However, they can be louder and require fuel and oil.
Cutting Width

This is how wide a path the mower cuts with its string. A wider cutting width means you’ll finish your job faster, especially in large areas. Look for something that fits the size of your yard and the areas you need to trim.

Cutting Height Adjustment

Some mowers let you change how high or low the string cuts. This is helpful if you need to trim grass to a specific length or deal with different types of overgrowth.

Wheels and Maneuverability

Good wheels make a big difference! Look for sturdy wheels that can handle uneven ground. The way the mower is designed will also affect how easy it is to push and steer. Some have larger rear wheels for better control.

String Feed System

How the trimmer string gets fed out is important. Some have automatic feed, which is convenient. Others might require you to bump the head to release more string. Easy string replacement is also a plus.

Materials That Matter

The materials used in a string mower affect its durability and how it holds up over time.

  • Frame: A strong metal frame, like steel, will last longer than plastic.
  • Wheels: Rubber wheels offer good grip and are less likely to get damaged than plastic ones.
  • Trimmer Head: Look for a durable trimmer head that can withstand tough use.

What Makes a Quality Mower?

Several things can make a walk-behind string mower better than others.

  • Engine Power (for gas): A stronger engine means it can cut through thicker weeds more easily.
  • Battery Life (for electric): For battery models, a longer battery life means you can work for more time without stopping to recharge.
  • Build Quality: How well the mower is put together matters. A well-built mower will feel solid and not wobbly.
  • Ease of Use: If it’s hard to start, push, or change the string, you won’t enjoy using it.

Things that can lower the quality include flimsy plastic parts, weak engines, or a design that makes it hard to maneuver. If a mower feels cheap or difficult to control, it might not be a good investment.

User Experience and When to Use Them

Using a walk-behind string mower is generally straightforward. You push it along the area you want to trim. The spinning string cuts down tall grass and weeds. They are great for:

  • Cleaning up overgrown areas after a long absence.
  • Trimming along fences, walls, and garden beds where a regular mower can’t reach.
  • Maintaining areas with thick, tall weeds that would clog a standard string trimmer.
  • Tackling slopes or uneven terrain.

The experience is usually about controlling the mower and guiding it. Some models might vibrate more than others, which can be tiring. The noise level is also a factor, especially with gas models.


Frequently Asked Questions (FAQs)

Q: What is a walk-behind string mower?

A: It’s a mower that uses a spinning string to cut grass and weeds. You push it like a lawnmower, and it’s designed for tougher jobs than a regular mower.

Q: Are gas or electric walk-behind string mowers better?

A: Gas models are usually more powerful for tough jobs. Electric models are often lighter and easier to start, with battery models offering cord-free use.

Q: How wide is the cutting path?

A: Cutting widths can vary, but many are around 18 to 22 inches. A wider path means you finish faster.

Q: Can I use it on a regular lawn?

A: While they can cut grass, they are best for overgrown areas or weeds. For a neatly manicured lawn, a standard lawnmower is usually better.

Q: How do I change the trimmer string?

A: Most models have an easy-to-access trimmer head. You’ll typically need to unscrew a cap and feed new string through, or use pre-wound spools.

Q: Are they hard to push?

A: It depends on the model and the terrain. Well-designed mowers with good wheels are easier to push. Gas models can be heavier.

Q: What kind of maintenance do they need?

A: Gas models need oil and fuel changes, and spark plug checks. Electric models require less maintenance, mainly keeping them clean and ensuring the battery is in good condition.

Q: Can I use any string with it?

A: It’s best to use the type and thickness of string recommended by the manufacturer for your specific mower.

Q: How do I store it?

A: Store it in a dry place. For gas models, it’s good practice to run the fuel out before long-term storage.

Q: Are they noisy?

A: Gas-powered models can be quite noisy. Electric models are generally much quieter.
