Antonio - If you live in South Florida, chances are your lawn is a St. Augustine type of grass. And yes, this is some of the toughest grass to cut with a reel mower. If you have a thick grass like a St.Augustine, a Zoysia, or a Bermuda, you are going to need a heavier weight reel mower to plow through the thicker blades of grass, and that means it's going to be harder to push. I would recommend the Fiskers Momentum reel mower. Fiskars reel mower The Fiskars weighs more than a conventional reel mower, but the forward position of the reel and the versa-cut height adjustment will probably give you the best performance when it comes to managing thick grass like you have.
