I recently received my pro mower module - considering selling my original mower as a result. Module was just replaced by Yarbo as my original module’s bumper stopped working. This module has approximately 5 mow jobs in it - ie) like new!
I’m located near Madison, WI and am mostly interested in local pickup (shipping logistics seem annoying to deal with as a seller). Included would be two additional cutting discs and many blades (I had spares from original given I broke a few while learning mapping dos and do-nots. 
Also contemplating keeping this module around to have a spare - entertaining offers.
