Hello bestseller and Admin Deejay

Well, it is amazing what turns up on these forums!
Thank you bestseller for supplying this most valuable image.

It appears to be an illustration that accompanied a
patent application for the edger. Any any information on
the document would be appreciated. Do you have a full copy?

This diagram has explained an unknown - that the PTO did not
require a modified crankcase, but power was taken by the
meshing of exposed gears driven from the blade holder!

Like the Predicta a bit of an awkward folly.
I'm glad this one never went into production.

All very on the edge.
