how often do you guys sharpen blades? and before some of you blast me with the 'do a search you newbie loser' i went through 3 pages of search on sharpening blades before i gave up. last season we sharpened them nearly every day (by the way, that is ALOT of blades for us). but i am thinking that if they don't hit anything and if the weather is not bad, we should be good for at least 2-3 days, maybe a week. what i would really like to do is change that item on the daily maint. schedule from change blades to check blades and move change blades to the weekly maint. schedule. what do you all think?
