Hi Spaceman:

Dummy me, I was not thinking but it would be easy enough to mount
the axle backward in the first place. Senior moment, I have a not so
new excuse.:}

I really doubt anyone will ever wear one out doing this ,that was good
to begin with. Heat and dirt are the enemies and how much are you
going to use the thing? Replacing it should be much easier than
building it the first time. One idea would be to get the differential
from a medium duty truck , 1/2 ,2 ton etc. It should eliminate any
worry about failure and it would mix a bigger load or multiple loads
at once.
The engine and drive train from a medium truck would allow you to
drive a generator and a pump as well.


I can tell you the sound is unpleasant and magnified by the square of
the distance back home.
