I keep having this nagging thought that I should be balancing my blades on my CC 42'' deck. It has a large center blade with two small outer blades. I have never balanced the blades but I'm sure that has a direct effect on spindle life. Of course I want to do it myself. Anyone have quick and dirty way to do this?

I've got a small plastic balancer I use. It's similar to this.

My dad always used a putty knife. If he could get it to almost balance on the edge, it was close enough.
I've done it that way and I also have a plastic tipi style.

Somewhere, I have a spun aluminum one, but it's whatever is closer.

The nail or knife will tell you two dimensions, the tipi will tell you all three.

Out a screw in the edge of my work bench. I don't do it everytime I sharpen my blades. I always sharpen mine with a file and a whetstone, so I'm not removing huge amounts of metal.

All of those methods work well, however I have found with the star in the middle blades my spun alum balancer will not work. I took a 1/2" X 6" bolt and a 5/8" X 6" bolt and cut the head off and rounded the cut off on the grinder. I stick the threads in the vise and slide the blade over it. It works pretty well and didn't cost to much. JM2CW.

I've used one of those too.

 

I got a source where I was able to get the mulching blades for my Craftsman for about $6 each.  At that price it wasn't worth the hassle of trying to sharpen the curved cutting edge on the blade.

 

I suspect blades for the Simplicity ZTR will be expensive enough I'll have to dig out that old balancer.

Screw driver in the centre of the hole of the blade and hold it up vertical and see if it drops either way down. Then file to balance.

I wish they would make a mower blade with replaceable sickle blades. It seems the more dents the blade gets, the uglier the thing becomes.

Nail in the wall.

 

Was talking too a few guys at work recently and they thought I was nuts. They said it made no difference; Told them I have never replaced a deck bearing/spindle; they all wanted to know the secret. Wall balance; even the push mowers. Harmonics are a witch.

I was never happy with hanging a blade on a nail and less impressed using a cone balancer. I finally figured out why. A good percentage of the blade weight is suspended below the pivot point using a nail and all of the weight using the cone. This masks a good portion of the out of balance condition.

 

Have been able to find a small ball bearing intended for woodworking router bits that has an OD that matches the blade hole diameter. They use a very light lubricant so turn easily. Hanging the blade on that centers the blade on the pivot point and is very accurate. Do it indoors as the slightest breeze will windmill the blade.

That has been done in the past, but the idea never caught on.

I have one of the aluminum cone balancers if got from my dad.  I use it a lot of times but not all the time.  I sharpen my blades with the blade held in a vise and use a 4" angle grinder with grinding disc.  Easy to keep the same angle and with light pressure it makes a nice even cutting edge.  Don't use the mowers to grind up rocks to the blades will last several cuttings.  When a nick does show up, I balance the blade again.
