ok, i have a client who is against the use of any spray or chem. organincide, however, he has a moderate sized patch of poison ivy in the woods that he wants mowed down. now there is no way i will use the new mowers on this, as there is debris in the area. i have an old murray lawn tratcor that i could use, or i could just weed whack it. my concern is if i use the mowers, then the poison ivy will be spread everywhere/. what would you do?
