Unlike other models that struggle with limited spray width or slow pump response, the NorthStar Tow-Behind Trailer Sprayer 21-Gallon stands out with its robust 2.2 GPM open flow pump. I’ve used it on tough terrain, and the higher PSI (up to 70) and built-in durability make spraying tasks quicker and less frustrating.

This sprayer’s large proprietary tank with UV-resistant walls and its 120-inch boom deliver broad, even coverage, which saves you time. Its reliable Viton valves and Santoprene diaphragm ensure it resists chemicals and lasts through frequent use. I found it easy to prime, thanks to the on-demand pump, and it handles pesticides confidently without clogging or leaking.
