WCOH | Need some help.
John Deere 7200 12 row finger units. Flex front fold. Tractor is 86 series IH tractor. When folded out the wings will drop lower then the center when lowering. The center section stops then the wings are delayed on there stopping time and stop lower. When you get it leveled out and planting across the field then the center of the planter will drift lower then the wings. On long fields you can see a visual difference between rows 6 and 7 because the center is lower. This unit has a pilot operated directional valve on the hitch. 2 hoses to the planter and 3 hoses to the tractor. We have 2 of the hoses connected to the hydraulic valve and the 3rd connected to a direct return to tank. I removed the filters in the master cylinder they were clean not plugged.
Any help would be appreciated.
