How To Balance Bush Hog Blades?

Arne

Get from somewhere a spacer that will fit snugly in the blade holes and not quite as thick as the two blades stacked. Whatever you get needs to have a hole in the center you can feed some all thread through and put a large washer on each side that is bigger than the blade hole. Lay the blades on edge on a flat work bench with the holes lined up and one blade pointing to the right and the other pointing to the left. Assemble the wizz bang widget hickey that I clearly described above and tighten the nuts on the all thread nice and snug. I think in this case a picture would be worth a million words but what you aend up with should look like a lawn mower blade with a hunk of all thread somehow perfectly centered in the arbor hole with a few inches of thread sticking out each side.

I this seems confusing I more than understand. I am starting to loose track myself but anyhow, now you can place the all thread stubs on the smoothe and very level jaws of a vice that is left open a bit and the heavy blade will fall. Grind away at that side untill it will balance.

Lots of room for improvement in the above but you just bolt the blades to one another to look like a mower blade in any way you can to make sure the all thread is centered and let the law of gravity do the rest.

Good luck,

Saw a demonstration where wheel weights were moved about on a trailer tire and then rotated at different rpm's. The bearings would slide around dependent on the rpm's and the axle, tire, and rim were always in balance.

This rig was a development of the racer, Bobby Allison. At one time, a lot of police and trooper cars had them.
