St. Augustine Lawn Mowers Buying Guide

When shopping for the best lawnmower to tackle your St. Augustine lawn, there are several things to consider—and several things to look for. Here we have compiled just a few of these factors to make your shopping experience a little faster and more effective.

Manual vs. Electric

Because of the manner in which St. Augustine grass grows, it is often better to go with a reel mower than a gas-powered lawnmower of some kind. And within the category of reel mowers, there are essentially two kinds: manual reel mowers and electric reel mowers, both of which we have reviewed above. Electric mowers can offer you some push assistance when tackling large expanses of lawn. However, they also have more moving parts, which may mean they will need more maintenance down the road.

Cutting Head Width and Ease of Pushing

The cutting head or cutting wheel on these reel mowers come in various sizes. Those with small cutting heads are perfect for very small yards and might be a little easier to push. Mowers with larger cutting heads can cut more grass in a single pass, making them much more economical in terms of time, albeit harder to push in some cases. Some mowers have added technological advancements that make pushing easier, so if this is a concern for you it pays to look at the large and small print.

Height Adjustments

Some of the better mowers may offer height adjustments between ½ inch to 4 inches, while others do not offer as many height adjustments.

7-Blade Reel vs. 5-Blade Reel

Five-blade reel mowers are typically better for tall grasses like fescue, while 7-blade reel mowers tend to handle the bent grasses like Bermuda and St. Augustine much more efficiently. Hence, if you are looking for a lawnmower to cut your St. Augustine lawn, it’s best that you look for a 7-blade reel mower.

Handle Type

Some of the reel type mowers we reviewed come with a straight horizontal handle, while others have switched to a loop design for their handles. In most cases, this is a mere matter of preference, but some users have reported easier pushing with the latter-style of handles.


Reel mowers, which work great on St. Augustine lawns, tend to vary in price—usually between roughly $70 and $300 (varies by retailer). Naturally, some of the more expensive models are going to come with more features. However, if you only have a very small patch of grass to mow every week, you may be able to get away with a more affordable model.


Although reel mowers do not require the same level of maintenance as gasoline-powered mowers, they have been known to break down. And when they do, you are going to wish you had a warranty. Most warranties are good for 1 year all the way up to 4 years—so this is definitely something you should consider.
