Raising/Lowering Product
Refer to Figure 20
Product raising/lowering relies on the four lift cylinders at
the mainframe and wing end gauge wheels.
The product
must be raised for folding and unfolding.
The product will not lower if transport locks are installed.
See “ Lift Cylinder Lock-Up ” on page 30.
 When unfolded, if one or both markers are extended,
they may drag or shove if left extended during raise or
lower operations. To avoid this, fold markers prior to
raise or lower.
Machine Damage Risk (Hydraulic Hitch Only):
Do not lower product while folded without using the special
procedure on page 30 (this is a hydraulic hitch restriction -
product may be lowered while folded with standard 3-point
hitch).
Machine Damage Risk:
Do not lower while any product folding operations are
underway or partially complete, with either hitch.
Machine Damage Risk:
Always raise the product for any reverse/backing operations.
