Chapin 63950 4 Gallon Mixes on Exit™ (M.O.E.) Backpack Sprayer

Designed for lawn and garden applications, the backpack sprayer has a single 4-gallon polyethylene, clean water tank, and 2 smaller chemical concentrate tanks. The seals and gaskets are chemical-resistant to handle professional lawn and garden chemicals.

The Chapin 63950 M.O.E. backpack sprayer comes with 2 concentrate tanks to swap out as needed and it’s easy to install. Simply snap the tank in place and set the dial to accurate dispense your preferred weed killer, fertilizer, or pesticide. Additional features include padded backpack straps with lumbar support, cushion-grip shut-off, and poly wand. Additional concentrate tanks are available and sold separately. Made in the USA with global materials and backed by Chapin’s 2-year limited warranty.
