Your spreader is designed to evenly fertilize your lawn with nutrients it needs for growth, color, root strength and overall health. The active ingredients in lawn fertilizer are important for plant growth, root vitality and overall health. Late summer and early fall are the best times of the year to fertilize your lawn. The summer is an excellent time to give your lawn a healthy boost. In the fall, fertilizing gives your lawn extra strength to help it through the winter. This spreader features a 1/4 acre (14,000 sq. ft.) coverage area (depending on material used and speed of application), durable rust-proof poly hopper and spreader plate, and pneumatic tires that allow for easy maneuverability.
