I recently replaced the center blade on my RC60-71B mower, but I am having trouble with the blade. After tightening, I can definitely make the blade rock or wobble back and forth. The two outer blades don't do this! I don't own a torque wrench and am tightening the blade as tight as I can with a pipe wrench (no cheater bar). Once I start mowing, the center grass isn't getting cut and I can hear the blade hitting the shrowd. It seems like the blade isn't turning and when it does "catch" it hits the side of the mower. The first time this happened, the blade bolt was very loose to the point of coming completely off.
I didn't pay attention during disassembly with regards to the positions of the cup washers. There seems to be enough room, in my opinion, for another washer when everything is assembled and tight. I really would like some advice on the proper placement of the cup washers and if this issue has happened to others (and their "fix").
Thanks!
