I have a field I've hayed for the past 20 years. One year many years ago I made the serious mistake of driving on it too early in the spring when it was wet and made some big ruts. I've reached my limit on getting the heck beaten out of me driving over them when I hay every summer. Last summer I tried plowing under a section of it as a test and it was only modestly successful as plowing sod (at least for me) was troublesome so I just pulled a disc over it for what seemed like forever to get it relatively smooth. I'm thinking this time I might spray a portion of it with glyphosphate to kill the grass and then just disc it smooth. Seems with the grass dead it would be much easier/successful to smooth things out. Is this a good approach?? Should I disc it first then try to plow it then disc again?? Appreciate your thoughts.
