north central Oklahoma | Now, having heard that comment, I wonder if the metal is not what it once was. I got a bunch of French metal in some blades one time that was crap. As a general rule, if it is rolled correctly, it should be back to original concavity, and temper of the metal not affected.
I have a roller, haven't used it in years, but rolled a neighbors disc one time. He called back and said he couldn't pull it anymore. I went to field and noticed that he had it burried to the hubs, he had always taken all the hyd blocks off and ran with wheels up. Duh.
Like I said, if done right, it will provide a much sharper cutting edge. What many perceive as a sharp edge is not sharp at all when one takes into consideration the direction of travel the disc is travelling. That 1/4" or more of flat surface right adjacent to the "sharp edge" actually holds the disc out of the ground, along with the other 20, 30, or more blades with 1/4" flat edges.
I'm putting my money on metalurgical issues or operator (roller) error. | |
