NEW TO ME 1780 JD PLANTER HAVING TROUBLE AFTER A RAIN GETTING SEED COMPACTED AT ONLY .5 INCHES DEEP HOW DO YOU GUYS SET YOUR V CLOSING WHEELS.  SEEMS WHEN THE RAIN COMES IT LEVELS THE FIELD AND THE MOUND LEFT BY THE V CLOSING WHEELS MAKES SOYBEAND DEEPER. IF I DECREASE THE DOWN FORCE PRESSURE IT WILL NOT CLOSE THE SEED TRENCH ONLY RUNNING IN FIRST NOTCH OF DOWN PRESSURE.  THIS IS DISC OR FIELD CULTIVATED GROUND.  TRIED BRINGING THE CLOSING WHEELS TOGETHER ALL THE WAY WITHOUT REMOVING THE BUSHING JUST THE WASHERS.  I SEE SOME PEOPLE USING DRAG CHAINS BUT I WOULD RATHER NOT DO THAT (I HAVE MY REASONS ROOTS, ETC.). TIA.
