Adjusting Deck Lift Speed
Finding the proper Double Windrow Attachment (DWA) deck lift speed is essential to its proper operation. The deck must
rise fast enough to clear a windrow, and slow enough not to stop abruptly against the bottom of the windrower.

Figure 3.4: Auxiliary Valve Block and Deck Lift
Speed Valve
The deck lift valve uses hex socket screw (A) to lock the
adjusting knob into position. Loosen the locking screw enough
to allow the adjustment valve to turn. Do
NOT
remove the
screw. Tighten the screw after your adjustments are complete.
To adjust the deck lift speed:
•
If the deck lift speed is too fast, turn adjuster knob (B) to
the right.
•
If the deck lift speed is too slow, turn adjuster knob (B) to
the left.
NOTE:
The lift valve only restricts the lift speed of the DWA. The DWA
deck drop speed remains constant.
3.3.2
Adjusting Draper Shut-Off Switch
The draper shuts off automatically when the deck is raised about 2/3 of the way. If the deck does not shut off soon enough
(resulting in the backsheet touching the draper before it shuts off), the switch at the linkage needs to be lowered.
