We had an Excello when I was growing up, my had decided to upgrade to a Toro self propelled around 1964, it was not nearly as good. Not sure what happened to the Excello, must have been junked at some point.
Also had a Homoko (or was it Homko) heavy duty self propelled. It was like a bushhog on wheels, ended up putting the engine on a homemade pump for the garden.
