To add, adding more pressure to the fat packing wheel via the top link will force the closing discs down. Shouldn’t take much adjustment.

This.

First things first, though. Make sure you’re not putting the planter down too far and making the planter tilt forward on its head. You want your parallel linkage bars running level to the ground. You also want your toolbar to be level too. The deeper your hitch, and the more your planter is sitting on the head of the unit, you’ll easily plant into moisture, but the less your closing system is going to do well.

If your whole planter is running level, and you’re still having problems, then can start fooling with the closing system. Tilt it back a round or two at a time to start putting more pressure on the press wheel... If you’re still having trouble, then adjust the tension down to the closing wheels.

You want to keep the planter as level as possible though. The further you tilt it back, your planting depth will begin to get erratic.

If you can’t be fairly level and close, you probably need some new, or more aggressive, closing disks.

Can you adjust the pitch of the closing disk any? Like, make them pinch harder towards the seed trench?
