Had my last PGM on the grinder today doing a relief grind . I noticed a little hop in the grind once in a while . On closer inspection I found the finger was hitting some welds , so I took care of them with the cut off wheel . Last relief grind for this one . I'm glad where getting new flexes this spring , other wise I'd have to replace the reels on a few of the pgm's to get them to cut at .120 ". Where taking the old greens mowers (pgm 2006) and bumping them up to tees . So this reel will be fine for another season at .500" HOC . With my past experience with these mowers I know I can spin grind them a while more before they are done .
