Well i have over 14 years of ex. I go to a hardware store and get a thin sheet of masnighte <(Misspelled) size 4 x what ever hight feels good to you i also like a short spray wand that way i can hold my own trim board " back to the board i like to round the edges that will slid on the ground this will make it slid better and won't grip so much and in the middle i like a to take a quater round and with dry wall screw make a grip make sure u only use one side or u will make a mess good luck this way is cheap, flexable ,and if the drive has a bush just slid it under the branches and lift up and spray away if you have it clean.
