Can self - propelled lawn mowers cut thick grass? That's a question I get asked a lot as a supplier of self - propelled lawn mowers. And the answer isn't as straightforward as you might think.

First off, let's talk about what makes grass "thick." Thick grass can mean different things. It could be long, overgrown grass that hasn't been mowed in a while. Or it could be grass with a high density, where the blades are packed closely together. Some types of grass, like Bermuda grass or Zoysia grass, tend to grow thick and dense naturally.

Self - propelled lawn mowers come in different types and sizes, and not all of them are created equal when it comes to cutting thick grass. There are gas - powered, electric, and battery - powered self - propelled mowers.

Gas - powered self - propelled lawn mowers are often the go - to choice for cutting thick grass. They usually have more power than their electric or battery - powered counterparts. Take the 173cc 21 - in Gas Self - propelled Reel Lawn Mower. With a 173cc engine, it packs a punch. The larger engine size means it can handle tougher jobs. The self - propelled feature helps you move through the thick grass more easily, as you don't have to push as hard. The 21 - inch cutting deck is also a plus, as it can cover more ground with each pass, saving you time.

Another great option is the Craftsman Store 163cc 22 - in Gas Self - propelled Lawn Mower. The 163cc engine provides sufficient power to cut through thick grass, and the 22 - inch cutting deck gives you even more coverage. The self - propelled system on this mower is designed to adjust to your walking speed, so you can move at a pace that's comfortable for you while still getting a good cut.

But it's not just about the power. The type of blades on the mower also matters. Sharp blades are essential for cutting thick grass. Dull blades will tear the grass instead of cutting it cleanly, which can damage the grass and make it look ragged. You should regularly sharpen or replace the blades on your self - propelled lawn mower, especially if you're dealing with thick grass often.

Now, let's talk about electric and battery - powered self - propelled mowers. These mowers are more environmentally friendly and quieter than gas - powered ones. However, they generally have less power. For light to medium - thick grass, they can do a decent job. But if you have really thick, overgrown grass, you might run into some problems. The motor might struggle to cut through the grass, and you may have to make multiple passes to get a clean cut.

The condition of your lawn also plays a role. If the thick grass is wet, it's going to be even more difficult for any mower to cut through it. Wet grass clumps together, and it can clog the mower's cutting deck and discharge chute. So, it's best to mow your lawn when the grass is dry.

If you're dealing with extremely thick grass, you might want to consider using a mulching blade. Mulching blades are designed to cut the grass into smaller pieces and then distribute it back onto the lawn. This can help break down the thick grass and also add nutrients to the soil. Some self - propelled lawn mowers come with mulching capabilities, or you can purchase a mulching blade separately and install it on your mower.

When using a self - propelled lawn mower to cut thick grass, there are a few tips to keep in mind. First, don't set the cutting height too low. If you try to cut the thick grass too short in one go, the mower might bog down. Instead, make multiple passes, gradually lowering the cutting height with each pass. This will make the job easier on the mower and ensure a better cut.

Second, take your time. Don't rush through the job. Let the mower do its work at a steady pace. If you try to push the mower too fast, it won't be able to cut the grass properly.

In conclusion, self - propelled lawn mowers can cut thick grass, but it depends on the type of mower, the power of the engine, the sharpness of the blades, and the condition of the grass. Gas - powered mowers are usually the best choice for thick grass, but electric and battery - powered mowers can work for lighter thicknesses.
