Just in time for wheat topdress season, I have for sale 74 Chafer adjustable liquid stream bars from Needham Ag sales. These were used one year for topdressing wheat. They worked great; I just no longer own a sprayer. These are for 15-inch spacing.
Phil Needham says these provide more uniform N coverage, and less leaf tissue burn. 
New, they are $22 each; I’ll sell them for $11 each and free shipping within the 48 states.
