Buying Guide for Best Lawn Mower for St Augustine Grass

St Augustine grass is a popular lawn choice due to its ability to withstand heat, shade, and foot traffic. However, it requires proper maintenance, including regular mowing, to keep it looking healthy and attractive. 

To achieve the best results, investing in a lawn mower specifically designed for St Augustine grass is essential. In this useful guide, we will explore the key factors to know when selecting the best lawn mower for St Augustine grass.

Mower Type: Rotary or Reel

When choosing a lawn mower for St Augustine grass, you have two options: rotary and reel mowers. For St Augustine grass, rotary mowers are generally recommended due to their ability to handle the thicker blades of this grass type.

Cutting Height Adjustability

St Augustine grass thrives when it is mowed at a specific height range. Therefore, choosing a lawn mower that offers cutting height adjustability is crucial. 

Look for a mower that allows you to set the cutting height between 2.5 to 4 inches, as this is the ideal range for St Augustine grass. Adjusting the cutting height ensures that you can maintain the grass at the proper length for optimal growth and health.

Engine Power and Size

Consider the power and size of the lawn mower’s engine. St Augustine grass can be dense and tough, so a mower with a powerful engine will make it easier to cut through the thick blades. Look for a mower with an engine size of at least 160cc or higher for effective cutting performance.

Self-Propelled or Push

Decide whether you want a self-propelled or push mower. The self-propelled feature is especially useful for larger yards or if you have physical limitations.

Grass Clipping Management

Consider the grass clipping management system offered by the lawn mower. Some mowers have a side discharge option that expels clippings to the side, while others have a rear bagging system that collects clippings in a bag for easy disposal. 

Additionally, some mowers offer a mulching feature, which finely chops the clippings and returns them to the lawn as a natural fertilizer. Choose a grass-clipping management system that aligns with your preferences and your lawn needs.

Cutting Deck Size

The cutting deck size determines the width of the mower’s path in each pass. For St Augustine grass, a wider cutting deck is generally more efficient as it reduces the number of passes required to mow the lawn. 

Consider a mower with a cutting deck size of 21 to 24 inches for smaller yards and 26 to 30 inches for larger yards. Remember that a larger cutting deck may result in a heavier and bulkier mower.

User-Friendly Features

When choosing a lawn mower for St Augustine Grass, consider its user-friendly features. Look for features such as easy-start systems, ergonomic handles, and adjustable handles that provide comfort and convenience during operation. 

Additionally, some mowers may have features like quick height adjustment mechanisms or easy-to-access controls, making them more user-friendly and efficient to use.

Brand Reputation and Warranty

Consider the reputation of the brand and the warranty offered by the manufacturer. A reputable brand is more likely to provide good customer support and honor their warranty terms, giving you peace of mind with your purchase.

Additional Attachments and Features

Some lawnmowers may offer additional attachments or features that enhance their versatility and usefulness. For example, certain models may have a trimmer attachment for edging or a dethatching blade for removing thatch from the lawn. 

Assess your needs and consider whether additional attachments or features benefit your St Augustine grass lawn.

You can ensure a well-maintained and healthy St Augustine grass lawn by evaluating these aspects and choosing a mower that meets your specific requirements.
