After posting about problem attaching mower, Steve Bieberich sent me pictures of the pins I was missing. Today I built a set for the mower. I took old stabilizer pins(5/8) cut ends off, cut head off a 3/4 bolt and welded them together.Beveled 3/4 nut to fit in mower arms.Cost $10 for 3/4 bolts. Hope this helps if someone else is having problem. I think they will work until I come across original set.I will post pictures after I get mower on tomorrow.
