What to Look for Before Buying the Best Self Propelled Lawn Mower For St Augustinegrass
Choosing the right self-propelled mower for St. Augustine grass involves more than just picking the most powerful model. This specific grass type has unique needs that must be met for a healthy, beautiful lawn. Here’s what to consider.
Find Your Need - Compatibility and use case considerations
First, assess your lawn. How large is it? Is it flat, or does it have slopes and hills? For large, hilly yards, a rear-wheel-drive self-propelled mower with a powerful engine (gas or high-voltage electric) is crucial for traction and performance. For smaller, flatter lawns, a lighter electric model might be more convenient. St. Augustine grass is thick, so a mower with a high-torque motor (brushless for electric, high CC for gas) is non-negotiable to prevent bogging down. Also, consider your storage space; many new electric models offer space-saving vertical storage.
Budget - Setting realistic price expectations ($X-$Y ranges)
Self-propelled lawn mowers for St. Augustine grass can range from around $350 to over $800.
- $350 - $500: In this range, you’ll find reliable entry-level electric models (like the MightyMow 17.9”) and some basic gas mowers. They will have self-propel and decent power but may lack advanced features like smart technology or extra-long battery life.
- $500 - $700: This is the sweet spot for many homeowners. Here you’ll find powerful cordless mowers from brands like Greenworks and WORX, offering excellent runtimes, smart features, and durable steel decks. High-quality gas mowers from brands like AMERISUN also fall in this category.
- $700+: This is the premium tier, dominated by high-voltage systems like the EGO POWER+ models. Expect market-leading runtimes, innovative multi-blade cutting systems, and superior build quality.
Key Features - Most important technical specifications
- Cutting Height: St. Augustine grass should be mowed high (between 2.5 and 4 inches) to promote healthy growth and deep roots. Ensure the mower has a height adjustment range that comfortably includes these settings. A single-lever adjustment is a convenient bonus.
- Power Source: Gas offers raw power but comes with maintenance, noise, and fumes. Battery-powered mowers are quiet, eco-friendly, and low-maintenance. For St. Augustine, a high-voltage system (60V-80V) or a dual-battery 40V system is recommended to ensure sufficient power.
- Deck Size: A wider deck (21-25 inches) means fewer passes and less time mowing, ideal for larger lawns. A smaller deck (18-20 inches) is more maneuverable for smaller, complex yards.
- 3-in-1 Capability: The ability to mulch, bag, or side-discharge gives you flexibility. Mulching is particularly beneficial for returning nutrients to your lawn.
Quality & Durability - What to look for in construction
Look for a mower with a steel cutting deck. While poly decks are lighter and won’t rust, steel is more durable and resistant to impacts from rocks or roots. For cordless mowers, a brushless motor is a must-have. They are more efficient, run cooler, produce more torque, and have a much longer lifespan than older brushed motors. Check for sturdy wheels with good tread and solid-feeling handles and controls.
Brand Reputation - Importance of established manufacturers
Sticking with reputable brands like Greenworks, EGO Power+, WORX, and established gas-powered brands like AMERISUN is a wise choice. These companies generally offer better build quality, more reliable performance, and accessible customer service and warranty support. They also have established battery platforms, allowing you to use the same batteries for other tools like trimmers and blowers.
Portability/Size - Considerations for space and storage
If your garage or shed space is limited, look for models that offer vertical storage. This feature, common on many modern cordless mowers, allows you to fold the handle and stand the mower on its end, drastically reducing its footprint. Also, consider the overall weight of the mower, especially if you need to lift it over obstacles or transport it. Battery mowers are often lighter than their gas counterparts.
Is it A Wise Decision to Buy self propelled lawn mower for st augustinegrass?
Investing in a self-propelled lawn mower specifically for St. Augustine grass is an exceptionally wise decision for several reasons. St. Augustine is a dense, thick-bladed grass that creates significant resistance. Using a standard push mower on this type of turf can be an exhausting physical battle, especially in the heat and humidity where it thrives. A self-propelled mower eliminates this struggle, turning a strenuous chore into a comfortable walk. The mower does the work of moving forward, so you only need to guide it.
This reduction in physical effort is not just about comfort; it leads to a better-quality cut. When you’re not struggling to push, you can maintain a consistent, steady pace. This consistency is key to achieving an even, clean cut across the entire lawn, preventing ragged edges and stress on the grass blades. Furthermore, the power required to drive the wheels is separate from the power spinning the blade, meaning the mower is less likely to bog down and stall in thicker patches. This ensures the blade maintains its optimal speed for a healthier cut. While the initial cost may be higher than a basic push mower, the long-term benefits in time saved, physical relief, and superior lawn health make it a worthwhile and intelligent investment for any homeowner with St. Augustine grass.
What Is the Best Way to Choose self propelled lawn mower for st augustinegrass?
Choosing the best self-propelled mower for your St. Augustine lawn involves a thoughtful, step-by-step approach to match the machine to your specific needs.
1. Assess Your Lawn’s Demands: Start by measuring your lawn size. For yards under 1/4 acre, most battery mowers will suffice. For 1/4 to 1/2 acre or more, look for models with long runtimes (like the EGO POWER+) or consider a gas-powered option. Note the terrain. If you have significant slopes, a rear-wheel-drive (RWD) model is essential as it provides better traction than front-wheel-drive (FWD) when the bag fills up or when going uphill.
2. Select the Right Power Source:
- Battery/Cordless: Ideal for most users. They are quiet, low-maintenance, and eco-friendly. For tough St. Augustine grass, prioritize high voltage (60V+) or models with advanced dual-battery systems.
- Gas: Choose gas if you have a very large property (over 1/2 acre), extremely thick or often-overgrown grass, or simply prefer the unlimited runtime and raw power of an engine.
3. Prioritize Cutting Deck Features: The deck is where the magic happens. For St. Augustine, ensure the height adjustment goes up to at least 4 inches. A single-lever adjustment system makes this process quick and easy. A durable steel deck is recommended for longevity. Also, decide if a wider 25-inch deck for efficiency or a more nimble 21-inch deck for maneuverability better suits your yard’s layout.
4. Avoid Common Mistakes:
- Ignoring Height Settings: Don’t buy a mower that can’t cut high enough. Cutting St. Augustine too short is one of the fastest ways to damage it.
- Underestimating Power Needs: Don’t assume any battery mower can handle thick turf. Look for high-voltage models with brushless motors.
- Forgetting Ergonomics: Look for adjustable handle heights and comfortable controls. A feature like Greenworks’ Smart Pace or MightyMow’s adjustable speed can make a huge difference in user comfort.
5. Budget vs. Upgrade: If you’re on a tight budget, focus on the core essentials: a reliable brushless motor, a steel deck, and the proper cutting height range. A budget model like the MightyMow 17.9” is a great start. If you can invest more, upgrading gets you significant quality-of-life improvements like longer runtimes, smarter technology (WORX Intellicut), superior mulching (EGO Select Cut), and enhanced comfort features. An upgrade is often worth it for larger lawns or for users who want the best possible finish.

You should expect to spend between $400 and $700 for a quality self-propelled mower capable of handling St. Augustine grass. In this range, you’ll find powerful and reliable cordless models with features like brushless motors and long-lasting batteries.

Durability, via a steel deck, is also a key consideration.
How do I maintain my self propelled lawn mower for st augustinegrass? For electric mowers, maintenance is minimal. Keep the underside of the deck clean from grass buildup, sharpen the blade once a season, and store the batteries in a cool, dry place. For gas mowers, you’ll also need to perform regular oil changes, replace the spark plug and air filter annually, and use a fuel stabilizer during the off-season to protect the engine.
Are expensive self propelled lawn mower for st augustinegrass worth it? Yes, for many users, they are worth it. More expensive models, like the EGO POWER+, often justify their cost with significantly longer runtimes, superior cut quality from advanced multi-blade systems, better build materials, and longer warranties. If you have a large lawn or desire a pristine, professionally manicured look, the investment in a premium mower often pays off in performance and longevity.

Greenworks and EGO Power+ are leaders in the high-performance cordless market, offering powerful motors and long-lasting batteries. WORX is known for its innovative technology.

Brands like MightyMow offer budget-friendly models that still include essential features like a brushless motor, adjustable speed self-propel, and adequate height settings. While they may not have the longest runtimes or the most premium features, they provide a fantastic self-propelled experience for smaller yards and are a great entry point into easier lawn care.
