Thanks guys. I will see what I can manage, attaching to the rear hitch with the blade raised. If I can't get enough clearance, I'll try attaching directly to the boom of the blade and go carefully. At some point I would like to get a hydraulic top link which would enable me to get that rear blade right out of the way.
I do used a dynamic recovery strap and, if possible, request stuck person to attach it to their vehicle, in the hopes it absolves me of any liability. Maybe that's just wishful thinking on my part?
