OPERATION
3. Raise and lower can be controlled with the GSL
buttons A, B, and C. Unlike the control through GSL
or console, up and down will be express, meaning
completely up or down. Refer to Section
2.6.1 Setting
One-Touch-Return Buttons (A, B, C), page 22 .
Figure 3.4: GSL – One-Touch-Return
The DWA’s deck height is displayed on the Harvest
Performance Tracker (HPT) as shown.
The DWA is
normally either up or down, so only one of these will show
on screen at any given time. It is possible to stop raising or
lowering the deck by letting go of the buttons. In this case,
the DWA defines up or down as disengaged or engaged
respectively.

3.3.1 Adjusting the Deck Lift Speed
Finding the proper Double Windrow Attachment (DWA) deck lift speed is essential to its proper operation. The deck
must lift fast enough to clear a windrow, and slow enough not to stop abruptly against the bottom of the windrower.
The deck lift valve uses an hex socket screw (A) to lock the
adjusting knob into position. Loosen locking screw enough
to allow the adjustment valve knob (B) to turn. Do
NOT
remove screw. Tighten screw after adjustments.
Refer to the following to adjust the deck lift speed:
• If the deck lift speed is too fast, turn the adjuster valve
knob (B) to the right.
• If the deck lift speed is too slow, turn the adjuster valve
knob (B) to the left.
NOTE:
The lift valve only restricts the lift speed of the DWA. The
DWA deck drop speed remains constant.
