Choose the tank that suits your needs – 1,000 or 1,200 gallon tanks in poly or stainless steel construction. Stainless steel tanks have integrated saddles. A deep sump design allows for complete draining and less product waste.

Select a manual or electric 100-gallon rinse system option to flush the solution tank. A convenient fill station area next to the ladder makes it easy to fill the rinse tank.


You can cover acres in a hurry with boom widths up to 120 feet. The high-strength, truss boom or mono boom system provides outstanding reliability for the toughest conditions. When product coverage is critical, the Guardian rear boom models can also be configured with the optional Spray-Air® boom systems.


The simple, reliable mechanical drive system used on Guardian Rear Boom Sprayers transfers more power to the ground for higher productivity, better fuel economy and lower operating costs.

Electronically controlled Cummins engines meet Tier 4B standards and provide high torque rise for added power when you need it.

Cummins QSB 6.7-liter engines power all three rear-boom models. These gutsy engines respond with extra power when needed, yet are the quietest in the industry for their horsepower range. Engines meet strict Tier 4B standards to keep air clean and reduce your farm’s carbon footprint.

All Guardian Rear Boom Sprayer models use the same stacked, one-pass cooling package. Instead of modules being layered front to back, they are positioned on top of each other so they all receive the same, cool air flow. The high-volume fan pulls air through the entire system in a single pass, allowing for more efficient flow of cooler air through all of the cores for maximum efficiency.

A crop clearance up to 48 inches allows you to perform. The structural steel front axle features massive 2.5 inch kingpins and bushings. A full 11 inches of suspension travel provides for a very smooth ride. The rear axle features a heavy-duty design with formed steel receiver tubes to handle harsh ground conditions. The active suspension system uses four air bags, gas shock absorbers, trailing arms and a large-diameter anti-sway torsion bar to keep the boom parallel to the ground. This system maintains a constant height and smooth ride.
