    Best thing I ever did was buy a Impact Wrench.

    I'll be doggoned. I have checked around and can't seem to find a Stihl mower, either.

    Anyhow, use a pair of leather gloves so you don't hurt yourself and get a wrench and then be careful (even dull, nicked blades can rack your knuckles & leave them bloodied). If the blades are rusted or gooped on, try some WD-40 or Liquid Wrench and let it sit for a few minutes.

    I'm with superman, above, if you don't quite have the juice to get the bolt to budge, you might need to get ahold of an impact wrench.

    Jyst as important, though, is when you go to put blades back on the mower. Torque them down to the specified tightness. You don't want it coming loose on you at several thousand RPM.

    Wedge a piece of 2x4 in between the deck and blade so that it will not move. Then get a piece of pipe and stick over your breaker bar or socket driver making it longer. More leverage,makes it alot easier.

    Lets see now-- 'righty tighty' or 'lefty loosey' unless you are working upside down then i guess it would be 'lefty tighty' and 'righty loosey'.. But wait we have bolts with 'left hand thread' and bolts with 'right hand thread' - Hmm - I wonder which a Stihl 48 might have.. Mabe a rule of thumb would be 'to loosen turn the bolt in the opposite direction of the blade rotation'.

    All the good tools have been previously mentioned..

    John Gamba has THE BEST solution. If we can see a pic odds are we will be able to figure out how to remove the blades.
