The adjustable nozzles thumb screw loosens and the neck floats up/down to open or restrict the flow rate to the slinger plate. This is to allow adjustment for large material like corn or fertilizer and small material like seeds. The slide valve on the front of the hopper allows additional opening or restriction at the hopper opening to the spout. These two adjustments combined will allow these units to be fine-tuned for precise applications.FeaturesUV stabilized rubber latch4-Prong Tail Light Adapter IncludedWireless ReceiverAdjustable NozzleMounts onto a 2" receiver hitchSpread food plot mixQuickly spread fertilizerSalt your driveway ( Large Salt )Spreads feed, seed, salt & fertilizerCorn Senderos and Trails
