On site balancing needed for a 50" Fecon Mulcher head on a skid steer machine in Richmond VA.

I field balance this type of machinery on a frequent basis, but this is located outside my normal service area.   Anyone in this area want to give it try?

Ted,

I can't do it but I know a guy nearby who would be a great match for this guy. He's a really good mechanic with lots of balancing experience.

Hard to believe it balanced that well considering what he was saying made very little sense. I’m guessing the predetermined positions of the tach and laser take lag into consideration. They may also have a factor written into the program that accounts for some or all of it.

Edit(Stupid autocorrect on iPhone)
I was thinking the same Rusty, No doubt it’s designed for simplicity as they aim that product at a regular joe in the field with basic mechanic skills.

The balance system sold by Fecon and shown in the video appears to be for single plane, and it was shown as a 2-step procedure for each end of the rotor. The balance sensitivity (ips/gram-inch) must be from Fecon (the OEM), but I suspect it might not be as accurate when balancing a rotor with worn/missing teeth that would change rotor mass. The calculated balance weight (grams) must assume standard mounting radius (in or mm). The location of heavy spot probably relies on the standard tach and accelerometer mounting positions. 

Here is a link from the video to balance analyzer:
