The Ecolawn Self-Propelled Multi-Purpose Top Dresser spreads a wide variety of materials such as compost, natural fertilizers, corn gluten, pelletized products, calcite clay, crumb rubber, sand and even salt. It is completely self-propelled and highly maneuverable, even up steep and uneven grades. Adjustments to mechanical systems are simple and require very basic hand tools. Multiple grease fittings are easily accessible to assure long bearing life. This unit will fit through a standard 36-inch gate. Loading and unloading the Ecolawn Top Dresser from your truck is a simple exercise.
