Re: (ET) Gator Blades

[Barry Woods <barry woods wright edu>]

Right.  There are two sets of metal baffles, one for rear discharge and one
for side discharge.  My deck has neither installed and does not have the
rubber strip on the rear dishcharge, and the side discharge chute is also
wide open.  I found the deck in a junkyard and whoever the original owner
was, had apparently removed the underdeck baffles.

If any of you want to try the Gatorblades you might want to experiment with
and without the baffles.  I suspect there will be too much drag on the
blades with them installed, but it would interesting to have someone do amp
measurements with and without the baffling.

baffle for the rear discharge mower.  Page 10 of 26 shows the baffle for 
the
side discharge mower.
