The last couple of months when mowing my customers lawns that have bermuda tiff, I keep getting these brown dormant or dead plugs (stems) of grass that are being sprayed out ( open discharge ) over the top of the grass. They are not easily dispersed with the blower since they are 3" in length. The lawn is nice and green but it seems the blades are pulling up these dead stems of grass and blowing them over the whole yard. It almost needs to be raked. I dont have as much a problem if I use my 21" that mulches but I really dont want to go that route everytime. thanks for any advice!
