Just recently, a few of my customers have started to complain about me putting a little grass into their beds and onto their cars. I do my best to blow what little grass is in the beds and on the cars away, but whatever is left there is nothing i can do, and i always thought it was no big deal. but 2 people asked me to have it remain perfectly clean. any techniques to avoid this problem or am i just going to have to use a bag. I have a 48 Exmark Metro.
