Solo 120cm 4-Nozzle Spray Boom – Even Blanket Coverage for Large Lawns & Garden Beds
If you're spraying a large lawn with a single nozzle, you're working harder than you need to. The Solo 120cm 4-Nozzle Spray Boom covers 1.2 metres in a single pass — cutting your application time dramatically while delivering more consistent, even coverage than any single-nozzle wand setup can achieve.
Perfect for applying herbicides, fungicides, liquid fertilisers, wetting agents and insecticides across large lawns, garden beds, and open areas. Compatible with a wide range of Solo manual and battery-powered pressure sprayers.

Why Use a Spray Boom Over a Single Nozzle?
With a single nozzle wand, getting even coverage across a large lawn takes careful, overlapping passes — and it's easy to miss strips or over-apply in areas you've doubled up on. A 4-nozzle boom eliminates that guesswork entirely. Each pass covers 1.2 metres consistently, the four nozzles deliver a uniform flat fan pattern across the full width, and the ball valve filters prevent dripping between rows so you're not accidentally dosing areas twice. The result is a more accurate application, less product waste, and a better outcome — whether you're applying a selective herbicide where accuracy is critical or a wetting agent across a large open lawn.
