How to select Best mower for St. Augustine grass?
St. Augustine is surely a thick turf but it not as difficult to mow as some other warm-season grasses. While choosing a lawnmower for St. Augustine grass, the choice comes down to following two options
- Reel Mowers
- Rotary Mowers
Reel mowers, generally have 3 to 7 blades that spin vertically and employ a scissoring action to cut grass. Reel lawnmower will help you get the aesthetic look for the lawn that you have longed desire.
Reel mowers ensure finer grass cutting without doing any damage to the roots. These mowers are easy to use and cut precisely like a pair of scissors.
Reel mowers are eco-friendly and do not require gas, oil, fumes, or charging thus saving hundreds of dollars of maintenance cost.
The decision to get mower for your St. Augustine must depend on how big your lawn is and how much time is spent on mowing. Reel mowers are suitable for smaller lawns.
As they are man-powered, mowing bigger lawns with push reel mowers will tire one out. As per some websites, reel lawn mowers are suitable for areas 10000 sq ft or less.
If the St. Augustine lawn has inclines, lumps, divots, then get push reel mowers, to work for the uneven terrain. Reel mower gives an even cut irrespective of the imperfections of the lawn.
Reel mowers do not quite fit in the frame when cutting tall grasses. If St. Augustine grass is kept at 1 to 2 inches, reel mowers work. Taller than 1 to 2 inches, reel mowers fail to seal the deal.
Rotary Lawn Mowers
A rotary lawnmower is different than its counterpart, reel mower. Blades of rotary mowers move horizontally and employ a sucking and tearing action to cut grass clippings.
Rotary lawnmowers are made for flat landscapes as pushing a real motor up the hill won’t be easy.
Horizontal mower blades need replacement or sharpening at least once a year. Rotary mowers work well for medium to large-sized lawns.
Rotary tilling mowers work like a pro in cutting taller grasses. If a gardener wants to mow St. Augustine grass above 2 ½ inches tall, rotary mower gets the job done.
Rotary Mowers are expensive to purchase. The upkeep cost also adds fuel to the fire. These mowers need oil, charging or gas to operate which also adds to the cost.
