Each fall Lawn Doctor (L-D)visits my neighbor and uses a Power Seeder. It appears power seeder scratches the surface and embedes grass seed. Around 3 weeks later, lawn is thick tall fescue. I don't know who the manufacturer of L-D's power seeder is however, if anyone knows of a power seeder that performs the same as L-Ds please pass along the information of manufacturer or their web address. Thanks!
