Chapin 61900 4 Gallon Backpack Sprayer Garden Pest Weed

Product Description

The CHAPIN 61900 is a 4-gallon polyethylene backpack sprayer built for field and grounds applications requiring extended coverage without frequent refills. The tank handles fertilizers, fungicides, herbicides, and general-purpose cleaning solutions up to 60 psi working pressure. A reinforced hose resists kinking and chemical degradation. The 20-inch stainless steel wand and brass nozzle assembly hold up to repeated use in corrosive environments. Three interchangeable nozzles allow technicians to shift between cone patterns as the job demands. Padded shoulder straps and lumbar support reduce fatigue during long application runs. Licensed applicators and grounds maintenance crews are the primary users.

The 61900 suits residential and light commercial grounds maintenance. Typical applications include weed and pest control, fertilizing turf and ornamentals, fungus management, and general surface cleaning. The 4-inch wide tank opening speeds filling and rinsing in the field. The in-tank filter catches debris before it reaches the pump and nozzle, reducing clogs during continuous operation. This sprayer is suited for licensed pesticide applicators, groundskeepers, and irrigation or landscape technicians who need a portable, self-contained spray rig with no power source required.
