Walk-behind sprayers roll along flat or gently sloped terrain to disperse liquid lawn treatments, surface-cleaning solutions, sealants, and more in landscaping, groundskeeping, and agricultural applications. They provide coverage for larger areas than handheld, cart, and backpack sprayers. Also known as push sprayers, they set their handle at a comfortable height for pushing while walking behind the sprayer. They require draining and rinsing out before storage to prevent chemicals from damaging sprayer seals and valves.
