Product Summary

Get your tractor revved up for this one-of-a-kind, Master Manufacturing 150 Gallon Premium 3-Point Broadcast and Spot Sprayer. Featuring a top-of-the-line pumping system that includes a 6 Roller Delavan Pump that reaches up to 20 GPM, adjustable pressure regulator, pressure gauge and boom lever that controls flow to sections of broadcast boom. In minutes, easily mount the heavy-duty all-steel frame to any category one tractor. Other features include a 12” vented screw-on fill lid for easy filling, 15’ of rubber hose with organizing rack and sump for easy draining after spraying. Backed by a two-year warranty on pump components. When it comes time to spot spray, un-holster your adjustable flash spray gun and reach up to 25ft. vertically and 30ft. horizontally from the comfort of your seat. As applications change, push down lever on the side of the spray gun and go from a steady stream to an atomized mist. The atomized spray gun is field repairable and features a trigger lock to reduce hand fatigue on longer jobs. This 3-point sprayer features a single mounted brass boomless nozzle that can deliver a 26ft. (half) or 52ft. (full) spray pattern. With a single mount setup, easily prevent damage from oncoming obstacles such as trees. Comes standard with one brass boomless nozzle. Designed to handle up to 21 acres* of coverage in one sitting, making it ideal for large spray applications with a category one tractor. *Acreage coverage is based on running spraying application at 30 PSI while maintaining speed at 5 MPH.
