Wow! and I thought I HAD a bad design!My operators manual for my mmm (RC60-24B) calls out a LH thread on the blade closest to the discharge chute but it is RH like the other two. I used a breaker bar to loosen and when I couldn’t budge that one I tried the old loosen/ tighten trick to break it free and it spun free when it should have tightened down. Got me wondering if I had an old design or a replacement spindle that the dealer just grabbed and used what he had.
