Mower comes with 14" rear wheels - they are HUGE. The largest casters
I found are 5" diameter - a little bit too small, but I will try.

I'm finishing edge segmentation right now. Low level processing is
very fast - real time easily. I'm not sure which way I will approach
real world modelling problem. Vision is monocular and color. Robot
will be initially restricted to my fenced backyard. Borders of grass
are easily detectable: fence, deck, framed playset, wall of the house
and edged areas with shrubs and flowers.
I will try to post regular updates of my progress.
