Setting Platform Draper Belt Angle
IMPORTANT: Adjustments to platform draper belt angle affect clearance between the feed drum and
the elevator chains on the combine harvester. It also affects clearance between
the crop throat
and the combine adapter.
Platform pitch and belt angle can be adjusted by 2 different methods.
1.
Loosen the lock-tab (B) and lengthening the
adjustable links (A) on each side of the adaptor to
lessen the pitch/belt angle or shortening the links to
achieve a steeper pitch/belt angle. Ensure an even
adjustment and lock-tabs are re-tightened after any
adjustment.
2.
Platform pitch and belt angle can be also be adjusted more aggressively by
moving the position of the pivot ball rearwards on the adaptor to lessen the pitch/belt angle or forward on the
adaptor to achieve a steeper pitch/belt angle. (Forward is the pre-delivery setting).
To Adjust Pivot Ball:
1.
Uncouple platform.
2.
Loosen 5 pivot ball bolts (C) and move to desired
position by moving adaptor .
3.
Re-tighten pivot ball bolts to 271nm (200ft-lb).
Note:
Always check feed drum to floor clearance and feed
drum to feederhouse chain clearance before running
machine.
Note:
