Thanks for the info,
I will check it out.
the little planter does a good job and corn comes up well.
I just have a small 6 ft disc and can never get the ground all that smooth,
when one sword gets in the cut left by the outside rear disc blade, I am concern there is not enough fill dirt to cover the corn and maintain the correct planting depth.
I thought these side plates might just be the ticket I was looking for to insure a more even planting depth and good seed cover.
