I have 20 acres that I let a friend mow for the hay. Two weeks ago he cut and raked and was able to roll 20 rolls. Then it rained. And it has rained enough to keep the unrolled hay go through several wet/dry cycles. I'm afraid the rows are killing the grass below the rows and rolls. Should I go ahead and mow the rows or how long should I wait? He has not contacted me due to his mother being put in hospice.
