FWIW -
My original knife kept breaking about 5" from the Pittman. I welded it back together too many times and finally gave up on it. I went to T-S for a knife, but all they had was 12' for some other make. I took some measurements and the blade would fit into the groove, so I bought 2. I used a torch to cut one to my Cub 22 mower length, and redid the attach points. I works well. I got them cheap, as the store was going to pitch them.

That often means that the hold-downs near the inner end of the bar are not holding down as closely as they should. The knife eventually fails due to metal fatigue.

That's exactly why it was breaking. As I became more familiar with how it works, I was able to make the retainer parts. I used half of a gate hinge and drilled new holes in the metal. Blade moves smoothly now.
