Gidday Jack,
The ODK site being the size it is I would not expect anyone could remember
every image.
I find the searchability on ODK is one of the easiest.
Yes the friction drive is a very old drive system now,I have seen images of
vehicles in about 1904 with the disc and wheel type of friction drive.
I was looking at the Snapper selfdrive images and it reminded me I have an
Ariens selfdrive walk behind mower with the disc and wheel friction drive.
I have a few selfdrive mowers I guess but I never use them,happy to push
a mower around in the sunshine and get a little exercise at the same time.
Thanks for your view on the Mobilco and Ariens Emperor.
I think this patent 1904 was the first to use an aluminium disc.
Regards Max.
