Chapin's HomePro 61821 4-gallon backpack sprayer is perfect for fertilizing, weed and pest control. It's an all-in-one home and garden sprayer. Easily, and comfortably, spray around trees, fence lines, shrubs, fields, and flowerbeds. With padded straps, back pad, and waist belt, it sits securely on your back, and the pump handle can be mounted for left or right-hand use. The 4-gallon poly tank is translucent to see the fill level; chemical-resistant seals provide additional compatibility with professional-grade fertilizers, weed killers and pesticides; and a 3-stage filtration limits clogs in the tank and line. Equipped with a 20-inch poly extension wand and 48-inch reinforced hose to give you the added reach needed to spray up and around taller foliage and exteriors.
