weight box attached to the windrower, proceed to Step
page 175.
If you are lowering the header lift legs WITHOUT a header
or weight box attached to the windrower, fully release the
tension in header float springs (A):
• If prompted by the Harvest Performance Tracker (HPT)
to remove the float, then remove the float and proceed
to Step 9, page 175.

proceed to Step 6, page 174

IMPORTANT:
When lowering the header lift legs without a header or
weight box attached to the windrower, ensure that the
tension on the float springs is fully released. This will
