Its so odd, i just cant remove my lawn mower blade.
The blade is attached to the mower using 3 bolts. The center bolt (which has the "37" written on it) is larger than the 2 others (which are located on either side of this center bolt). The 2 smaller bolts each have a nut screwed on, on the other side of the blade (towards the housing) making it difficult to get a grip and unscrew off so as to release these 2 bolts. The center bolt does not have a nut because it seems to just be screwed into some large base in the center of the mower -- its the area that makes the mower spin.
Now with that information, what tools must i use to get my blade removed? Are there specific sizes of tools i need for those bolts (recall i mentioned the center bolt says "37" on it.

Yes you do need a socket set and some wrenches . You can use them both together to remove them . The bolt in the center is screwed directly into the shaft . To break them loose you need to get a tire tool or similar tool to hold the blade in place while breaking the bolts loose .

Take another look at the bottom. The center bolt probably sits in a hole that goes through the blade (i.e. it isn't holding on the blade). That's a fairly normal setup.
You need to immobilize the blade so it won't turn the motor shaft while you're working. I've found a pair of vice grip pliers clamped on and rigged where they prevent motion works well. You should have pulled the spark plug wire before you started.
You may not need to get to the back side nuts. They may be welded onto the base plate. Once you have it immobilized, put a socket wrench on the small nuts and see if you can loosen them. If it turns on the back side, get another pair of vice grips and clamp them onto the nut on the back side. position the vice grip handles so that if the nut turns, the handle will be forced against the shaft stopping the rotation movement.
And when working on the bottom of a lawn mower, be aware that some of the bolts may have left hand threads! Look at them carefully.

If your problem is that the blade wants to turn as you try to loosen the bolts, just wedge a piece of wood, such as a chunk of 2x4 between the end of the blade and the interior housing. Sorry, but I don't know what the "37" means on that bolt. If you can't find wrenches that fit these bolt heads, us a pair of Vise Grip pliers and adjust them good and snug so they won't slip and mess up the bolt heads.

I use an attachment which hooks onto the deck to hold the blade in place. This allows you to get a better grip to unscrew the bolts. All my mower blades only have a center bolt though...

a crowbar or similar item to wedge the blade
you have to prevent the blade from rotating in order to break the nut free
dont try to hard the bolt may be a lefty tighty righty loosy instead of the conventional lefty loosy righty tighty
depends on the rotation of the shaft

you need the right socket for the center bolt. then a pair of gloves. grab hold of the blade and take the center nut off. that is the only nut that comes off uasaly.

usually only the center one is removed, the other two are probably providing the torque. it is also very possible that the center one has left handed threads.

Please don't attempt this without removing the spark plug wire & plug! It's easy to get hurt and hard to get well,,:-)=
