Re: (ET) mower blades

[Barry Woods <barry woods wright edu>]

I will contact Gatorblade about doing this.  I would like for someone to
double check my dimensions on the blade length and center hole, before I 
do.
Once again, I got 14 1/2" length with a 5/16" center hole.  It looks like
there is a little clearance between the blades, so we might be able to go 
up
to 14 7/8".

 If someone who has the ability to make a bushing (or could find a
compatible one) would try a set of Gatorblades, we can well how well they
work on an Elec-Trak deck before we commit to Gatorblade.

If they work well, an alternative would be to have someone who has the
ability to make a compatible bushing, like Timothy or Bill Gunn, see if he
would be willing to make and sell them to the group.  We could then use
these bushings on stock Gatorblades.
