3. If you are lowering the header lift legs WITH a header or
weight box attached to the windrower, proceed to Step 7,
page 234.
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 7, page 234.
• If not prompted by the HPT to remove the float, then
proceed to Step 4, page 233 to remove the float
manually.
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
prevent damage to the header lift linkages.
