Paul:

John Deere uses (I think it is out of production now, but still available
through parts) a waffle drive such as what was shown in the picture.  There
are also die cast drive components that fit it available.

We used the isolator between the engine and the hydraulic pump.  Very severe
duty.  The nice thing about this part is the failure modes.  The rubber is
trapped between the dogs, so it just stays there.

I will take a look tomorrow and see what I can find as far as cost, part
numbers and such.  Most likely, you will be able to go down to your friendly
John Deere dealer and just pick one up...

Regards-
Norm Muzzy

PS:  I know that I described this to someone, it was either on your list or
maybe it was directly to tracy.  To me, this would be the correct way to
couple the engine to the redrive.
