Hi Norm,

I've had similar mowers the same but not branded Ferrex and the electric start motor was useless , the one I had looked brand new
but had no compression. The reviews aren't good.

One I had was similar to a Baumer but I can't remember the brand ,looked very similar to the Baumr so it may
have been a Baumr, it was a 220 cc self drive and looked at least 3 years old and was still working good.

The reviews look ok but it can be bad luck if you get a bad one.I think you may need the 248 cc to get electric start about $600, the Ferrex is $300
