I've been pricing some weed wipers and weed sponges and they are rediculously expensive. The grass works weed wiper that is 20' is $8900 and a 20' kit from Smucker is $1000 and I'd still have to make a tool bar. So I got to thinking, I have an old 20' 3pt sprayer with tank. I went and bought two 10' "cattle rub socks" or what ever their called to keep flies off cattle's backs. I'm thinking of either zip tying the socks directly under the nozzles or splitting the sock like a hot dog bun and wrapping it around the nozzles and the length of the boom. I was also just going to use a 12 volt pump with 1/2" lines. What do you guys think is the best idea?
