Spray Nozzles

Bumper=mounted nozzles or raised, multi-section, nutating spray nozzles are typically used on county rigs. The following is one county’s description of both nozzle types:

A multi-section, nutating spray head allows a mindful operator to choose which section of the ditch to spray — in 2, 4 or 6 foot increments out to 30 feet. A system with multiple bumper-mounted nozzles can spray different distances too, but they tend to spray everything up to that distance. The mutli-section system uses less herbicide primarily by hitting a narrower band. But if operators of multi-section systems hit all seven switches every time they spray a single thistle — just to make sure they don’t miss — there won’t be much reduction in herbicide. Ultimately a good operator still makes the difference.
