Product Details
Most sprayer problems don't show up until you're already mid-job. The HD4000 4 gallon sprayer solves the biggest frustrations with smart design features that keep you working without interruption. The digital battery meter and translucent tank let you see exactly where you stand before you head out, so you're never caught off guard. When it's time to refill, the wide-mouth lid makes it quick and clean every single time. Whether you're controlling weeds, feeding your lawn, or doing spot treatments, the PetraTool’s electric backpack sprayer keeps up with the work without slowing you down. After spraying, rinse the tank, hose, and wand with warm soapy water, then run clean water through the sprayer for a few minutes to flush the pump and nozzles. A quick rinse of the filter screen keeps the flow strong and your spray pattern consistent next session.
Product Care
Fully empty and clean the tank before storing, then keep the sprayer in a cool dry place away from direct sunlight and freezing temperatures. For extended storage periods, remove the battery to preserve its lifespan and prevent gradual drainage.

Built for demanding jobs, the HD4000 Pro Series eliminates the hassle of manual pumping with a powerful 9Ah battery capable of spraying over 250 gallons per charge. The upgraded steel spray pistol and premium stainless steel wand are designed to withstand heavy daily use while maintaining consistent performance.

A translucent tank with gallon markers makes it easy to monitor fluid levels, and adjustable pressure from 40 to 70 PSI lets you tackle everything from delicate spraying to demanding applications. Double-padded shoulder straps provide exceptional comfort during long spraying sessions.
Product Care
After each use, empty the tank completely and rinse with clean water. Flush water through the hose, wand, and nozzles to remove any residue. Store the sprayer in a cool, dry location away from direct sunlight and freezing temperatures.
