i can see your guys reasonings for not sharpening as much as me. it makes perfect sense. we cut 25-40 lawns per day depending on where they are and how big etc, per crew i might add.
this makes me wonder just how much FF i will have to use in order for it to be ultra effective at keeping the underside of the deck clean or at least much easier to clean if some buildup occurs.
i put some on my garage rails today at home, much better.
i wish i had waited to put it on the shrub trimmers though, made sharpening today a bisnitch!!
