Now i don't usually post time saving tips or anything but i discovered a good one. Now I hate running my redmax weed whackers with out the guards because of the fact that you get hit with so much more crap, safety for my guys, and if the line gets too big you cant get it shorter without a knife, but i do love how quick we can knock out large areas of grass in minutes. what i discovered ( maybe everyone else is doing this and i don't know about it) is bend the guards up about an inch. this way you can run the line as long as you want and still be more protected from flying debris. but even better is if i want to cut the line shorter, i just step on the guard with one foot and flex it back down for a second till the line cuts and the it pops back up. now i don't know if anyone else has done this or you think its a stupid idea but it has been a really good time saving tool for me, i was wondering if this would help any of you guys.
