Living in Florida means dealing with thick St. Augustine grass, but this mower takes it on like a champ. Whether it’s dry or wet, this beast powers through with its electric torque, leaving my lawn looking immaculate.


One of the things that impressed me right out of the box was its sleek design. I mean, who says mowing the lawn can’t be cool? With its low profile and aerodynamic shape, this mower looks like it belongs on a race track. And the green finish? It’s like having a mini NASCAR in my garage. Plus, those larger rear wheels not only add to its rugged appearance but also make maneuvering a breeze, even for clumsy folks like me.

But let’s get down to business – the performance. The Greenworks 25022 delivers in spades. As soon as I fired it up, it felt like a match made in lawn-mowing heaven. The powerful 12 Amp motor and 20-inch cutting deck effortlessly handle the dense St. Augustine grass and whatever other mysterious flora populates my lawn. And trust me, those thick blades stand no chance against this mower’s cutting prowess.

Adjusting the cutting height is a cinch, thanks to the convenient single lever with 7 positions. It’s like being on a game show, except instead of spinning a wheel, I get to customize the height of the entire mower with a single hand. The only word of caution: remember to set it back to the right height! I got so caught up in the convenience and showing off that I left it too low once, resulting in a bald spot. Lesson learned, folks.

Let’s talk about mulching. While I don’t have much to mulch, when I do use it, this mower does the job beautifully. The clippings are well-chopped, and I’ve never encountered any clumps or grass remnants on my lawn. However, most of the time, I opt for the rear bagging feature. Why, you may ask? Well, my outdoor composter can get pretty gnarly with all sorts of creepy crawlies, and the last thing I want is to accidentally grab a handful of critters while emptying it. So, the bag catcher keeps things neat and convenient for me.

My Personal Experience:

As soon as I started using it, I could tell that this mower was a cut above the rest. Living in Florida, where St. Augustine grass reigns supreme, I was initially skeptical about finding a mower that could handle its thickness. But boy, was I pleasantly surprised!

I took my new Greenworks mower out for a spin, and it effortlessly sliced through the dense blades of St. Augustine grass without missing a beat. The 12 Amp motor and 20-inch cutting deck proved to be a formidable combination, delivering power and precision. Even when faced with wet grass, which can be a nightmare for many mowers, this beast powered through, leaving a clean and well-manicured finish.

Using the mower was a breeze. The easy push-button start eliminated the hassle of pull cords and priming engines, making the whole process quick and convenient. Adjusting the cutting height was a joy, thanks to the single lever with 7 position options. It was like having my very own lawn-mowing cockpit, where I had complete control over the height of the cut. Plus, the cam lock handle made folding and storing the mower a breeze, saving me valuable space in my garage.

I have to admit, there’s something oddly satisfying about mowing the lawn with the Greenworks 25022. It’s like a dance between man and machine, with each pass leaving a beautifully manicured trail in my yard.

It’s evident that Greenworks has put considerable thought and engineering into creating a mower that can handle tough conditions while still delivering exceptional results.


Now, let’s address a couple of minor drawbacks I’ve encountered. Firstly, this mower does require an extension cord for power, which is not included. It’s important to use a 14 gauge 50′ or 12 gauge 100′ extension cord for optimal performance. While it’s a small inconvenience, it’s worth mentioning.

Secondly, while the larger rear wheels contribute to easy maneuverability, the front wheels are slightly smaller. This can make turning a bit tricky, especially if you have uneven terrain or obstacles in your yard. It’s not a deal-breaker by any means, but it’s something to keep in mind.


  • Powerful 12 Amp motor tackles thick St. Augustine grass with ease.
  • Versatile 3-in-1 mowing options for mulching, rear bagging, and side discharge.
  • Easy push-button start and single lever height adjustment make it user-friendly.
  • Durable steel cutting deck for efficient and quick mowing.
  • Corded power eliminates the need for gas, oil, or emissions.


  • Extension cord not included, requiring a separate purchase.
  • Smaller front wheels may pose challenges when maneuvering.

My Opinion:

If you’re on the hunt for the best lawn mower for St. Augustine grass or any thick-blade grass for that matter, look no further. The Greenworks 25022 is here to slay the unruly beasts in your yard and leave you with a lawn that will make your neighbors green with envy.

Buying Guide: The Best Lawn Mower for St. Augustine Grass

As a caring gardener, you must have the right tools. And when it comes to St. Augustine grass, choosing the best lawn mower is crucial. St. Augustine grass is a warm-season grass variety that thrives in hot and humid climates, known for its thick and coarse blades. To keep your St. Augustine lawn looking its best, here are some key factors to consider when selecting a lawn mower:

Cutting Deck Size:

The cutting deck size of a lawn mower refers to the width of the blade and determines the cutting swath in each pass. For St. Augustine grass, it is recommended to choose a mower with a larger cutting deck, typically around 21 to 30 inches. A wider cutting deck will allow for faster and more efficient mowing, reducing the time and effort required to cover your lawn.

Adjustable Cutting Height:

St. Augustine grass has a preferred mowing height range of 3 to 4 inches, which helps it maintain its density and shade out weed growth – making it a potent shade-tolerant grass cutter. 

Look for a lawn mower that offers adjustable cutting height settings within this range. Having the flexibility to adjust the cutting height ensures you can tailor the mowing height to your specific St. Augustine lawn, promoting healthier growth and reducing stress on the grass.

Engine Power:

Consider the power of the lawn mower’s engine, as it plays a vital role in effectively cutting St. Augustine grass. The engine power should be sufficient to handle the thick and dense nature of St. Augustine grass. Look for a mower with a higher horsepower rating, typically between 6 to 8 horsepower, which will provide the necessary strength to cut through the grass with ease.

Self-Propelled or Push Mower:

St. Augustine grass can be challenging to mow due to its thickness, so deciding between a self-propelled or push mower is an important consideration. A self-propelled mower is equipped with a drive system that powers the wheels, making it easier to maneuver and push through dense grass. This feature can save you time and effort, particularly if you have a larger lawn. However, if your lawn is smaller or you prefer the exercise, a push mower can still be suitable for maintaining St. Augustine grass.

Mulching and Bagging Options:

Choosing a lawn mower with mulching and bagging capabilities can provide additional benefits when mowing St. Augustine grass. Mulching mowers finely cut the grass clippings and distribute them back onto the lawn as a natural fertilizer, promoting healthy growth. Bagging options, on the other hand, collect the clippings for disposal, keeping your lawn tidy.

Look for a mower that offers both options or allows for easy attachment of a mulching or bagging kit, providing flexibility for different mowing preferences.

Durability and Quality:

Investing in a durable and high-quality lawn mower is essential for long-term use and performance. Look for models from reputable brands known for their reliability and longevity. Read customer reviews and consider the warranty provided by the manufacturer to ensure you are getting a mower that can withstand the demands of mowing St. Augustine grass.
