I run a John Deere 7300 8 row 30 and I wouldn’t run without Rebounders. I really like the Rebounders in cotton planting. Better seed depth and all in the bottom of the furrow.
I had one missing last year during cotton planting. The seed spacing was not as good and the depth was better on the other rows. I saw seed close to the top on the row that was missing the Rebounder and it didn’t come up til it rained.
