I have had a successful lawn company for the last couple of years and am in the process of becoming a lic applicator. I am checking the different fert companies in my area and all seem to have similar products with not so similar prices. The problem is the support, two of the companies had specific spreaders they pushed and gave no information on any other spreader settings. Then I went to Lesco who seemed to have lots of service but a considerable higher price. I am wanting to run a couple of test bags on my property prior to putting it anywhere else yet I can not get much help. I know I run the numbers and calibrate but I would think that they would be a little more helpful. I assume they are like this in order to deter some of the fly by night operations. I guess I am looking for a little service.
