Wing Coupling Options
At time of initial planter ordering, one of the following
three options must be specified for wing to center section
coupling:
• Wing Lock (80)
Wings are rigidly coupled to center via tie bars when
afield. This configuration is only suitable for planting
strictly on flat ground.
• Wing Flex (81)
Hydraulic cylinders at the coupling allow the wings to
flex during planting, but keep them level during folding.
This configuration is suitable for most planting
situations.
• Hydraulic Down Pressure (80)
Wing coupling cylinders are actively controlled, and
used to transfer weight to the wings as needed in
challenging light no-till conditions on uneven ground.
For operation, see “Hydraulic Down Pressure
(Option)” on page 46 and see “Hydraulic
Down-Float Adjustments (Option)” on page 50.
For any of the coupling options, see pinning
requirements at “Wing Lock and Flex Lock Pin Use” on
page 22.
