I helped a friend move yesterday and noticed they were throwing away a 100lb push spreader (its works perfect). Since then I have been researching on overseeding so I could mabey add it as a service before the season starts. Then I thought about doing it without asking the customer. If I get an account in a nice neighborhood, I wouldnt mind buying a bag or two for the front yard just to make it look good (good advertisement). So, What are the outcomes of overseeding without scalping? Will I still get good results? Do you think it is worth the money to try and get other customers?
