Small Engines (Lawn Mowers, etc.): Riding mower tecumseh model OV358EA, cutting blade, drive impact

Question
I just purchased a new Tecumseh riding mower. I was attempting to try and remove the cutting blade so in the future when it needs to be sharpened I will be able to get it off.
I found it would not budge. The bolt holding it on under the carriage was on very tight. I did not want to turn too hard knowing that it may cause damage. I have taken many blades off push mowers and sharpened them but the blade on this mower seemed to be put on with way too much torque. It has 2 blades on this mower.
Can you give me any in-sight on how to remove this blade.
Thanks.

Answer
Hello Edward:

An Electric or Air 1/2" Drive Impact is Best for Removal of the Blade Bolts. If these are Not Avaliable, then a Pipe Wrench can be Used to Hold the Blade Adapter while you Loosen the Blade Bolt. Hope this Helps. I am Here if You Require More Assistance. Let me Know What Happens, Please. Thanks.

Good Luck
