Jim, I feel for ya...I really do and pray for a good recovery!
BUT..... Forest Gump said it best and I dont need to tell you that. I will wire open the discharge flap (half way) and just lift the front and sorta shake the grass out. How long have you been kicking that stuff? Man...seems dangerous to me! Scratch that...Is dangerous!
Hang in there. Im sure you'll heal up quick and fine.
