W seed trench on a John Deere 1720

I put brand new disk openers on both sides of my planter. I thought I put the right amount of shims in but still have this problem.

Trade them all in for harvest international precision planter

Yes... trade it in for a case planter that weighs twice as much as a deere that should solve your problem

Worked for us…

If your tool bar is not level this will happen because your blades are not cutting in the right spot. Adjust and try again

Not familiar with your kind of planting or dirt, what is your organic matter there? Just curious.

Make sure contact distance of the openers are correct. Not sure on a 1720 but on a 1790 it's between 2" and 1 1/2". Manual will tell you what it is for your planter. If you've got those to spec then my guess is the planter bar is not level.

Make sure to install the openers to correct calibration. I believe its 3 1/2 inches of contact at front of openers. Google it or get info from manual. Worth the time , we calibrate ours 3 times a year on 6 row on 1800 acres

2-1/2 inches. Take two business cards and slip in from top and bottom measure the distance between them

I like the Acra-plant seed tube guards or whatever them things are called. They eliminate that problem. You might try tipping your planter ahead a little. I’m used to a three point planter so it’s not a big deal to shorten the top link a little.
