Red Rover time-lapse video of the day. Today’s project was to attach the Woods PD-25 post-hole digger on Red Rover. Took a while to get it installed. Read the safety manual several times. When completed, dug the first of 170 holes for the deer fence project. Small issue of a bolt rubbing one of the safety shields, and a shear bolt falling out (didn’t shear, nut must not have been on tight enough). Tech from Belle Mead motors stopped by to fix the rubbing issue.
