Buying Guide for St. Augustine Grass Mowers
Cutting Quality and Blade Action
St. Augustine grass requires a sharp, scissor-like cut to prevent tearing and browning. Reel mowers like the Walensee and American Lawn Mower models use a precise cutting action that slices blades cleanly. This promotes a healthier lawn compared to rotary blades that may shred thick turf. Look for models with multiple blades for finer cutting.
Cutting Height Adjustability
St. Augustine thrives at higher mowing heights, typically between 2.5 and 4 inches. An adjustable cutting height is essential to maintain a proper height. The Worx Cordless Lawn Mower offers six positions from 1 to 3 inches, while the American Lawn Mower 1815-18 provides a range of 0.5 to 2.75 inches. Choose a mower that offers flexibility to suit seasonal growth. For larger lawns, consider our recommendations for best Husqvarna mowers for large properties.

For small to medium lawns, a push reel mower like the American Lawn Mower 1204-14 is lightweight and easy to maneuver. Larger yards may benefit from a cordless electric model such as the Worx, which offers battery power for greater coverage. Ensure the mower can handle your lawn’s terrain, including slopes or uneven areas. If you have a flat one-acre lot, check out our best Husqvarna robot mower for 1 acre guide.
