The PetraTools HD4000 is a reliable 4-gallon battery-powered backpack sprayer built for larger lawns, gardens, and farm work. Its upgraded 12V8AH battery delivers 6–8 hours of continuous spraying—over 200 gallons per charge—making it far more efficient than standard lithium sprayers. The double-padded straps and cushioned back support make long jobs easier, while adjustable pressure from 40–90 PSI and six included nozzles let you switch between fine misting and strong streams depending on your task. The wide-mouth lid prevents spills, the extendable wand improves reach, and the built-in screen filter avoids clogs for consistent performance. Backed by a U.S. family-owned company with 24/7 support, this sprayer offers dependable operation for weed control, fertilizing, watering, and general outdoor maintenance.
