how many of you take your trimmer guard off? I have seen many lawn comps do it...WHY? To me it seems that your engine is made to swing around a certain amount of string. It seems if u take the guard off u wouldn't be able to stop it from coming out futher than its supposed to and burn up the engine! It also stops some of the debri from flying everywhere and on you. The extra weight can't make much difference. So if you do take yours off...WHY???
