OPERATION
3.3.1 Adjusti
ngtheDeckLiftSpeed
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 to turn. Do NOT remove
screw. Tighten screw after adjustments.
Refer to the follow ing to adjust the deck lift speed:
• If the deck lift speed is too fast, turn the adjuster knob (B)
to the right.
• If the deck lift speed is too slow, turn the adjuster
knob (B) to the left.
NOTE:
The lift v
alve only restricts the lift speed of the DWA. The
DWA deck d
rop speed remains constant.
