870D: Air Assist Sprayer

Home PDF High Clearance Tractors 870d-air-assist-sprayer

The PDF 870D is built with the same rugged design required of our Detasselers. Fully equipped and ready for the most demanding field terrain, the 870D offers Exceptional visibility Enhanced operator comfort and greater productivity to increase profitability. Our Heavy-duty tubular Steel frame is designed to withstand all the rugged demands of conventional, ridge till, and no till farming. The Rear pivoting axle along with independent wheel suspension provides the best control and ride quality, while keep all wheels on the ground through even the worst field conditions. Our Specially designed leg configuration retains maximum strength with a minimal profile width allowing the PDF 870D to work in spaces and rows where others can't. A twin Hydrostatic pump drive combined with our Special 2-Speed 4-wheel drive system gives you the high torque needed for field operations yet allows road speeds up to 20 MPH to move between jobs. Outfitted with Saddle Tank style solution tanks, lowers the sprayer’s center of gravity, and provides unmatched stability. Twin high flow Centrifugal pumps offers redundant spray systems to minimize potential down time during time sensitive operations. Combining standard spraying tips and our Air-Assist curtain greatly increases coverage and penetration of any row crop. This approach not only helps directs the chemical to where it is needed but also provided a more uniform coverage at lower solution rates, stretching 600g to an effective 1000g equivalent.
