The grass has grown like nuts this year. The smaller yards or front lawns we always used the 21's on have become a PITA. It clumps out from under the decks , around the wheels and blowing is taking way too much time. What smaller WB do you use or do you use 21's? Been in buisness 5 years, worked w/ other co. 3 years before that. This is the worst I have had to deal with. Never did like 21 work.
