since i am new and need a wirebrush scrubbing i was wondering if anyone knew how not to leave mohawks when they mow? also, is it true i can hammer out bent blades? i bend my blades on a regular basis and when i keep using them my mower starts to make a funny sound...oh yea it's a 21' lawn boy with front wheel drive....please help! also how do i properly fertilize a lawn and do i really need a permit to spray pesticides at people's houses? what if i only work for cash and don't report my earnings, do i still need to take a pesticide test? oh yea, one more thing...i have found that if i price my lawns at half of what everyone else charges i get more accounts, has anyone else found this to be true? has anyone tried the new murrary?
