OPERATION
4.9 Double Windrowing
Double windrowing is laying two swaths side-by-side. Larger capacity combines or forage harvesters can then pick
up twice as much material in a single pass, saving time and fuel.
Double windrowing is performed with the D65 Draper Headers by two methods; deck shifting, or using the Double
Windrow Attachment (DWA).
Deck shifting is used for crops that don’t require conditioning, such as grains, canola, and beans for example. Refer
to
• 4.9.1 Shifting Decks Hydraulically, page 76 , or
• 4.9.2 Shifting Decks Manually, page 77
Forage crops such as alfalfa, hay, and some grasses are cut and then fed into the HC10 hay conditioner. The DWA
system allows double windrowing with conditioner equipped windrowers up to 30 feet. Refer to
4.9.3 Using Double
Windrow Attachment (DWA), page 78 .
4.9.1 Shifting Decks Hydraulically
The hydraulic deck shift feature allows the Operator to select center, left, or right delivery from the windrower cab.
It is only available on the 25, 30, and 35 ft. headers.
Refer to your windrower operator’s manual for identification and operation of the deck shift control.
Laying a Double Windrow
NOTE:
30 ft. headers equipped with transport or stabilizer
system, require that the wheels be in the raised position
to avoid interfering with the windrow.
1. Position decks at the left end of header to deliver crop
from right end (A) for the first round.
2. Shift the decks to the right end of the header with the
deck shift control in the windrower to deliver crop from
left end (B).
3. Complete the second round to lay a double windrow.
4. Repeat above steps to lay the second double windrow.
NOTE:
The end delivery opening is designed to give adequate
clearance between the first windrow and the standing
crop, and optimum space between the two windrows.
