Why is it so damn hard to get the "Owner's Manual" for the Toro product I purchased from a local Home Depot store several years ago?!!!! I've listed THE ONLY showing PART /SERIAL # that's affixed to the device and yet, try as I might, all I get FROM ANY of the so-called "sourced" is a list of....."TORO Trimmers at best prices"...................may I talk to somone who can help me????!!!!!!!!!!!!!!
