Top Air from Unverferth offers a comprehensive line of sprayers, from 550-gallon tank capacity (TA550) up to 2,400 in their biggest premium model (TA2400).
For a pull-type, the TA2400 is a large sprayer. It comes with an independent axle suspension and there is rubber cushioning on each side of the axle to independently absorb any rough terrain and ensure a smooth boom ride. FLO–BAK ball valves automatically return any remaining liquid in the plumbing at the time of shutoff back into the tank rather than the boom, saving chemical and money.

The large TA2400 has a three-inch intake for fast filling. Boom choices are 90, 110, 120 or 132 ft. The latter three offer a three-dimensional structure, where you can fold the outer portion of the boom over to spray smaller widths. There are also a number of wheel and tire options, including 14-inch wide tracks.
In between the TA550 and the TA1200-2400 series are the Top Air 112-116 models. These sprayers have 1,200-to 1,600-gallon tank capacities with 140-to 165-gallon rinse tanks for quick and complete cleaning. Boom choices include 60 (on the 112 only), 80 and 90 feet with boom heights from 19 to 76 inches. These booms have “wing-tilt” with hydraulic accumulators, which allows the operator to tilt from five degrees to 15 degrees above horizontal.
