Got the results form the weed control test I took last month and I passed. So this afternoon I sent in the $150 fee along with the forms. Now I have a question I have been looking at spray rigs trying to decide what I want too buy for next year. I am leaning toward purchasing a skid sprayer too put in the back of my truck and I am wondering how hard it is too get even coverage over the whole lawn. I know a lot of it depends on the operator and I would like to know what some of you do too remain consistent while walking and spraying.
