The EFG Series (Medium Duty) Flail Mower is an option if you are working on grass or brush. Ideal for an orchard, nursery, vineyard, in the greenhouse or for gardening. With its fast blade tip speed and interchangeable blades it is perfect for your groundskeeping tasks. By putting on the Grass Mulching Blades you can maintain the grass area around your home, plus cut and mulch small twigs. If you need to maintain more dense areas, install the Hammer Blades and you will be able to cut and mulch wooded material up to 2 inches in diameter.  This model is great for acreage of 15 or less. Flail Mowers are useful for jobs where you are cutting grass on uneven ground, high grass, weeds, brush, and wooded material. A flail mower doesn’t throw grass, instead it cuts finely and leaves the cuttings on the ground where it was cut making it an excellent choice for those places where you could cause damage by throwing debris. Highway mowing and park maintenance often use flail mowers because they are less likely to throw objects during cutting.
