Choosing A Tow Behind Dethatcher
How do you choose the best tow behind dethatcher?
Here are some things to consider:
Tow behind dethatchers come in a variety of widths. This affects the swath created with each pass up and down your lawn.
Wider dethatchers will get the job done quicker than narrower ones. But, they usually cost a bit more money as well.
How Much Weight Can It Carry?
Pull behind dethatchers usually have a weight tray above the tines that allows you to add extra weight.
This can help to clear thick and matted thatch more effectively. And can also be used to help you scarify and till the surface layer of the soil.
The weight that can be carried varies between brands. With around 70-lbs being standard. But some able to carry 150-lbs or more.
Is It Easy To Transport?
Some of the best pull behind dethatchers come with a lever that helps you to raise and lower the unit.
Raising makes it easier to transport along roads and over hard ground. And then you can lower it to the ground when it’s time to start dethatching.
Although the best tow behind dethatchers are built to last, sometimes things can go wrong.
Pulling your dethatcher up and down and dragging the tines along the ground can cause parts to bend and break.
So it’s good to check how long the warranty is before you buy.
1-2 year warranties are standard among the top-rated models. But you can occasionally find products with longer warranties as well.
Can Dethatching Hurt Your Lawn?
When you do it properly, dethatching is great for the health of your lawn. It helps nutrients, oxygen, and water to enter the soil for root uptake.
But you should do it at the right times of year when the grass is vigorously growing to avoid damage to your lawn.
When the grass is growing it can quickly recover from any injury caused by the dethatching. The best times to do it depend on the grass type.
For cool-season grasses, such as Kentucky bluegrass, early fall or late summer is the best time. For warm-season grasses, such as Zoysia grass, early summer is the best time.
Should I Pick Up Thatch After Dethatching?
After dethatching the thatch will be left lying on the top of the grass along with any leaves, twigs, pine cones, etc, that are pulled up.
So it’s a good idea to clean up. You can use a lawn rake or lawn sweeper to collect the debris. Another good option is a leaf vacuum mulcher.
What Is The Difference Between Dethatching And Power Raking?
Using a power rake is an aggressive way of removing thatch from your lawn. It’s only really needed for lawns with very thick thatch.
Whereas using a dethatcher is usually a lighter process that removes a thin layer of thatch from a healthy lawn to help with fertilizer absorption.
However, because you can add extra weight on top of a tow behind dethatcher you can dig through matted thatch and even into the top layers of the soil if you need to.
How Often Should You Dethatch Your Lawn?
A small amount of thatch is healthy for your lawn. So you only really need to dethatch when excess starts to build up. This will take a different amount of time on different lawns.
You should leave it until it’s an inch or more before taking action.
