Powerful, liquid-only sprayer for crop protection and insect control.
When you need to cover a large area, you need a high-capacity sprayer that is comfortable, powerful and fuel-efficient. With the SR 430 backpack sprayer, you can check off all those requirements and much more. This gasoline-powered liquid-only backpack sprayer delivers a large spraying range, reducing the time it takes you to treat large areas. Its high performance pressure pump provides a constant flow of product with no loss of pressure, regardless of the spray angle. While the engine is running, the pump also continuously mixes and agitates the tank contents, delivering a more consistent application of product. The sprayer is also comfortable to wear, featuring an anti-vibration system, soft rubber grips and optional chest and hip belt accessory to evenly distribute weight. The SR 430 is ideal for farmers, foresters and pest controllers.
