Re: (ET) Mower motor failure and blade balance

In 43 years of ET mowing (averaging 2 acres a week for 6 months of the 
year) I can only recall a single magnet failure. I use (2) tall motor 
decks; one for my lawn and another for vineyards.
Makes sense. The tall thin motors have never had a magnet failure that I have seen (I have several cores for those) the problem was always the darn armature shorting somewhere and causing the motor to "cog".
I'll take a look at the blade balance, I will say I do have more vibration than I should, but I think the bigger problem is whatever they used for adhesive is just wearing out.

I think the secret to my success is using a precision blade balancer. I use a 
MAG-1000 and it is amazing. https://www.magna-matic-direct.com/blade-balancers/ 
<https://www.magna-matic-direct.com/blade-balancers/>  The deck was much 
quieter and I have to believe it extends bearing life as well. Blade 
straightness can also be verified.

You may wonder how sensitive it is. In one of their videos they placed a sliver 
of paper on a 24” blade and the balancer moved.

I wanted to see if my old unit was still up to the task. So I did a quick test yesterday 
and a placed a 1” long piece of electrical tape on an ET blade tip. The tape made 
the balancer move! I’ve found that even brand new OEM blades can have their 
balance improved with this unit.

Yes, it is expensive but a wise investment in the long run.
