Cutting Width: 16 inches

Style: Push Lawn Mower

Weight: 37.5 pounds

Things we Liked!

This corded electric model is ideal for small yards as it only has a 16 inch cutting width. 

It also happens to be one of the lightest models on the market at just 37.5 pounds – making it incredibly easy to move around your yard! 

Not only does this machine have rear discharge and mulching capabilities (which help reduce grass clippings), but there are virtually no emissions produced by using this product; meaning it’s much better for both you AND the environment!

Please Consider!

First, the handle design could be improved. The handles are not ergonomic and can become uncomfortable after extended use. 

Second, this mower is not suitable for vast lawns; 

it will take significantly longer to mow a large area with this machine than it would with a larger model. 

Finally, keep in mind that the cord can be difficult to maneuver around obstacles such as trees or flower beds – you may need an extension cord if your yard has many obstacles

Guide for Mowing and Maintaining your St Augustine Grass

St Augustine grass is a type of turf grass that is commonly found in the southeastern United States. 

It is a warm-season grass, which means it grows best when temperatures are above 60 degrees Fahrenheit. 

If you live in an area with a climate that supports St Augustine grass, then you may be wondering how to care for it properly.

Mowing and maintaining your grass can seem like a daunting task, but it doesn’t have to be! With just a little bit of knowledge and effort, you can keep your lawn looking beautiful all season long. 

Here are some tips on mowing and maintaining:

Preventing Lawn Diseases

One of the most important things you can do to maintain your St Augustine turf is to prevent diseases from taking hold. 

Many common lawn diseases, such as brown patch and dollar spot, thrive in humid conditions – so make sure to water early in the day or not at all if possible (diseases love moist environments!). 

Additionally, fertilize regularly according to package directions – too much fertilizer can actually encourage disease growth; while too little will weaken your turf’s resistance against disease organisms present in soil.

Regular Mowing

Mow often enough so that no more than 1/3 of the leaf blade is removed at each mowing. 

This promotes vigorous new growth which helps crowd out weeds and improves the overall density & appearance of the strand. 

It also allows clippings to decompose quickly without the resulting smothering effect caused by thick layers.

Proper Fertilization

Applied correctly & timely, fertilizers provide supplemental nutrition needed for development beyond what’s available from naturally occurring sources In general, 4 applications spread over spring & summer months supply adequate nutrients.

Correct timing coincides with periods when newly applied nitrogen becomes available for plant uptake. 

Older leaves yellow first under inadequate nutrient availability signaling time for another application.

Ending Thoughts

There is no one-size-fits-all answer when it comes to finding the best lawn mower. 

The type of mower you need depends on the size and condition of your lawn, as well as your personal preferences. 

If you have a small yard, an electric push mower should be sufficient. If your yard is larger or has rough terrain, however, you may want to consider a self-propelled gas model. 

For especially large yards, a riding tractor may be the best option. 

When choosing a lawn mower for St. Augustine grass, it’s also important to consider your local climate and weather conditions. 

In areas with hot summers and little rainfall, choose a model that can handle drought conditions without damaging the turfgrass blades. 

Likewise in wetter climates, pick a machine that won’t leave puddles behind after each pass across the lawn surface

Now that you have an understanding of the best lawn mower for St. Augustine grass, you can focus on simply maintaining your lawn.

This process may include regularly watering and trimming your grass to ensure its health and vitality. In addition, consider using a fertilizer specifically designed for this type of turfgrass in order to achieve optimal results.

By following these tips, you can create and maintain a beautiful yard that will be the envy of your neighborhood.
