Quick Review For Top 9 Lawn Mower For St Augustine Grass
Greenworks 40V 16" Cordless Lawn Mower, Ultra-Light Push Mower with 4.0Ah Battery & Charger(75+ Tool Compatibility, 45Min Runtime)
The Greenworks 40V 16″ Cordless Lawn Mower is designed for homeowners who want a clean, quiet cut without the complications of a gas engine. If you have a small to medium-sized yard up to about a half acre, this mower offers a practical and surprisingly powerful alternative.
It’s built to simplify your lawn care routine from start to finish, focusing on ease of use and real-world value.
At its core, this mower delivers gas-like performance but without the fumes, loud noise, or ongoing maintence. A single 4.0Ah battery provides up to 35 minutes of continuous runtime, which is typically enough to cover that half-acre lawn, and it recharges fully in about two hours.
You’ll notice the difference immediately: it starts with a simple push-button, operates at a library-quiet volume under 75dB, and eliminates the need for ever buying gas or oil again. That quiet operation means you can mow early on a weekend without disturbing neighbors, and the savings really add up—potentially over $200 annually compared to a traditional gas mower.
One of the most appreciated features is its ultra-lightweight design.
American Lawn Mower Company 1204-14 14-Inch 4-Blade Push Reel Lawn Mower, Red
The American Lawn Mower Company 1204-14 14-Inch Push Reel Lawn Mower is a classic manual mower designed for simplicity and effectiveness. If you have a small to medium-sized lawn and are looking for a quiet, eco-friendly way to maintain it, this model is a strong contender. It’s a tool that gets back to basics, offering a clean cut without the noise, fumes, or complexity of power mowers.
This mower features a 4-blade reel system with a 14-inch cutting width.
The reel design is key—it uses a scissor-action cut that cleanly slices grass blades rather than tearing them. This is healthier for your lawn, as it doesn’t bruise the grass, helping to prevent brown tips and promoting thicker growth. For the best results, its recommended to mow frequently, cutting no more than one-third of the grass height at a time. The cutting height itself is easily adjustable from 0.5 inches up to 1.75 inches, giving you control over your lawn’s length.
It handles grass up to about 4 inches tall effectively, but performance can suffer if the grass gets much taller than that, so regular mowing is your friend.
Weighing only 19 pounds, this mower is exceptionally lightweight and easy to push. Its maneuverability is aided by durable 8.5-inch polymer wheels that roll smoothly over your yard. Since it’s manual, there’s no engine to maintain, no oil or gas to deal with, and no spark plugs to change.

The 13-inch cutting path is manageable for smaller yards and tight spaces. It collects clippings in a 6.5-gallon bag, which helps keep your lawn tidy.
The mower runs on the included 24V lithium-ion battery, providing up to 22 minutes of runtime per charge, though this will vary with grass thickness and height.

These range from a shorter 1.4-inch trim to a taller 3-inch cut, letting you adjust for season or your lawns specific needs. Just a simple lever adjustment and your ready to go.
Maneuverability is a key highlight.
The mower features larger 7.75-inch rear wheels that help it roll smoothly over your lawn, making it easier to navigate around trees, garden beds, and other obstacles.

LawnMaster LMRM1801 Push Reel Lawn Mower 18-Inch 5-Blade
The LawnMaster LMRM1801 Push Reel Lawn Mower is a straightforward tool for maintaining a smaller, well-kept lawn. If you have a modest grassy area and prefer a quiet, manual approach to mowing, this 18-inch reel mower offers a specific set of benefits that might align perfectly with your needs.
At its core, this mower is designed for a clean, healthy cut. Its five durable steel blades operate in a scissor-like action, cleanly slicing each grass blade instead of tearing it.
This method is gentler on your lawn, promoting stronger root systems and a lusher, greener appearance over time. You won’t have to worry about ragged brown tips or stressed grass after you mow.
One of the key advantages here is the complete lack of a motor. The LawnMaster LMRM1801 requires no gas, oil, or batteries. This means zero emissions, incredibly quiet operation, and no ongoing fuel costs or electrical cords to manage.
You provide the power, which makes it an environmentally conscious choice and provides a bit of light exercise. It’s simplicity at its finest.
For customization, you have significant control over your lawn’s look. The mower features nine separate cutting height positions, adjustable from 1.1 inches up to 2.5 inches. This lets you adapt to the season, grass type, or your personal preference for lawn height with relative ease.
Great States 204-14 Hand Reel 14 Inch Push Lawn Mower
The Great States 204-14 Hand Reel 14 Inch Push Lawn Mower is a straightforward tool for maintaining a smaller lawn. It’s a manual reel mower, which means it operates entirely on your power—no cords, no gas, no batteries. You simply push it, and the blades turn. This design offers a unique set of benefits and considerations that are worth understanding before you choose it. At its core, this mower features a 4-blade reel with a 14-inch cutting width.
The cutting action is a scissor-like shear, where the spinning reel blades meet a stationary bed knife. This provides a very clean cut for your grass, which can be healthier for the lawn compared to the tearing action of some rotary mowers. You can adjust the cutting height from 0.5 inches up to 1.75 inches to suit your grass type and preference. The 8.5-inch polymer wheels are designed to roll smoothly and offer good maneuverability around tighter spots and garden edges.
A significant advantage is the blades themselves. They are crafted from heat-treated alloy steel, which is built to hold a sharp edge for a very long time. When they eventually do need sharpening, it’s a service that can be performed, extending the mower’s life for years. This ties into the overall low-maintenance promise. There’s no engine to service, so you’ll never deal with oil changes, spark plugs, or stale fuel.
BLACK+DECKER Electric Lawn Mower, Weed Eater and Edger 3-in-1 Combo, Corded 12-Inch 6.5 Amp Electric Weed Wacker and Compact Push Mower (BESTA512CM)
The BLACK+DECKER Electric Lawn Mower, Weed Eater and Edger 3-in-1 Combo (BESTA512CM) is designed to simplify lawn care for smaller yards. If you have a compact lawn, a postage-stamp sized yard, or just need to maintain tight spaces, this all-in-one tool aims to handle your primary tasks without needing three separate machines cluttering your shed.
Its core appeal is multi-function convenience.
You start with a powerful 6.5 amp string trimmer for tackling weeds and grass along fences and walls. With a simple attachment, it converts into a compact push mower for the main lawn area. Then, by rotating the head, it becomes a wheeled edger to give you those crisp lines along walkways.
Switching between these modes is meant to be straightforward, letting you complete your entire lawn with one power source.
For performance, the motor uses a POWERDRIVE Transmission designed to maintain speed in thicker grass. The 12-inch cutting swath is narrow, which is ideal for maneuvering around garden beds and obstacles but means it will take more passes than a wide mower. It’s not for large, open acres.
Earthwise 1715-16EW 16-Inch 7-Blade Push Reel Lawn Mower, Grey
The Earthwise 1715-16EW 16-Inch 7-Blade Push Reel Lawn Mower is a modern take on a classic lawn care tool. It’s designed for homeowners who want a clean, healthy cut for their grass without the noise, fumes, or maintenance of a gas engine. This is a hand-push mower, meaning it’s powered by you.
As you walk, the 10-inch composite wheels turn the precision 7-blade reel, delivering a clean scissor-cut that’s actually better for your lawn’s health.
You get a 16-inch cutting width, which is a good balance for most small to medium-sized yards. It’s maneuverable and easy to navigate around trees and garden beds. The construction is built to last, with durable steel side plates and an alloy steel reel that’s a key feature.
This alloy steel is tough and stays sharp much longer than ordinary blades, so you get consistent performance season after season with minimal upkeep. The cutting height is fully adjustable from a low half-inch up to two and a half inches. This lets you find the perfect length for your specific grass type, whether you want a putting-green short trim or a taller, more drought-resistant lawn.
This mower isn’t just for standard Kentucky bluegrass.

Lawn Mower For St Augustine Grass Buying Guide
Mowing St. Augustine grass calls for a mower that delivers a clean, high cut. This thick, lush turf is beautiful but can be finicky. Using the wrong mower can tear the blades, leaving a ragged, brown look and opening the door for disease. The right tool makes all the difference for a healthy, carpet-like lawn.
Cutting Height & Adjustability
This is your top priority. St. Augustine needs a high cut, typically between 3.5 to 4 inches, especially in hot summers. A mower with a wide, easy-to-adjust height range is essential. Can you change the height with a single lever, or do you have to fiddle with each wheel? Simple adjustments save you time and ensure you never cut too short, which stresses the grass.
Mower Deck & Blade Type
Look for a high-lift blade paired with a well-designed deck. This combo creates strong suction that stands the grass up for an even cut before gently laying it back down. A clean, sharp cut heals faster than a ragged tear. A mulching deck is a great option too, as it finely chops clippings and returns them to the soil as natural fertilizer.
Power & Drive System
St. Augustine is dense. You need enough power to get through it without the engine bogging down. For small, flat yards, a robust electric model might suffice. For larger or slightly uneven lawns, a self-propelled gas mower is often the best bet. The self-propel feature takes the effort out of pushing, making it easier to maintain a steady pace and consistent cut.
Maneuverability & Grass Handling
How does the mower handle the clippings? A good side-discharge is useful for not overwhelming the grass with clumps when it’s a bit too long. Also, consider the mower’s turning radius. Can you easily navigate around your landscape beds and trees? Easy maneuverability means a quicker, more through job with less missed spots.
Frequently Asked Questions About Lawn Mower For St Augustine Grass
What’s teh best type of mower for St. Augustine grass?
A rotary mower with sharp blades is your best bet. Reel mowers can sometimes pull at this grass instead of cutting cleanly. You want a clean cut to keep your lawn healthy.
How high should I cut St. Augustine grass?
Keep it tall! Set your mower deck to cut between 3.5 to 4 inches high. Cutting it too short stresses the grass, making it vulnerable to weeds and heat damage.
How often should I mow?
Try to mow often enough that you never remove more than one-third of the grass blade height. In peak growing season, this might mean mowing every 5-7 days. It depends on how fast its growing.
Are mulching mowers a good choice?
Yes, they are excellent. A good mulching mower chops the clippings finely and returns them to the lawn. This acts as a natural fertilizer, which St. Augustine grass loves.
How important is blade sharpness?
Extremely important. Dull blades tear the grass instead of slicing it. This leads to brown, ragged tips and can open the door for disease. Sharpen your blades several times a season.
Should I bag or mulch my clippings?
Mulching is generally recommended for the nutrients it provides. Only bag if the grass is overly long or wet, or if you see signs of disease that you want to remove from the lawn.
Can I use a robotic mower on this grass type?
You can, but choose carefully. Ensure the robot mower can be set to cut at 4 inches or higher. Also, its frequent, light cutting schedule is actually quite good for St. Augustine.
What features should I look for?
Look for a mower with high, adjustable cutting heights. A powerful engine helps with thicker grass. Consider wider wheels to prevent ruts, as St. Augustine often grows in softer soil.
Our Verdict
Protecting delicate St. Augustine grass demands a mower with precise height adjustment and a consistently even cutting deck. This isn’t just about looks; it’s about the health of your lawn. A clean cut at the right height prevents scalping, reduces stress, and helps your turf resist weeds and drought. It’s the best defense you have.
When you choose a lawn mower for St Augustine grass, you’re investing in the long-term beauty of your yard. Take your time to consider the features that matter most for your specific situation. With the right tool, you can look forward to a thick, healthy lawn that feels great underfoot and makes your whole outdoor space look it’s best.
