Idler Roller Positioning
Position the idler roller bars at center opening as follows:
• wider opening sizes: hardware at (A) - used for John Deere*, New Holland TX/CX and Lexion 460, 465,
480 & 485 Combines.
• mid-range opening sizes: hardware at (C) - used for Case 80 & 88 Series, Case AFX, New Holland CR
970/980 and Lexion 450, 470 & 475 Combines
• narrower opening sizes: hardware at (B) - used for Case 60 & 66 Series, New Holland TR and CR
920/940/960 Combines.
NOTE: To achieve narrowest opening sizes, move complete deck assemblies inboard. Ensure outboard ends
of draper are still at least partially covered by wide crop deflectors.
The decks are factory assembled in the "mid-range” opening position with hardware at (C).
To change idler roller bars to wide or narrow position:
1. Loosen draper completely, and remove connector slats.
2. Remove hardware from positions (C) at front idler bar and at rear idler bar.
3. Move idler roller in or out as required and install bolts at holes (A) or (B).
4. Tighten bolt at front of deck only.
5. For proper draper tracking, check roller alignment as described on next page.
6. Tighten two bolts at rear of deck.
7. Reinstall drapers.
8. Repeat at other deck.
* NOTE: For John Deere CTS Combines with dust shields in
rice applications, adapter may have been converted to a mid-
size deck. In this case, use position C instead of A.
NOTE: For headers in rice using narrow end panel deflectors,
use hole C for wide feed deck and hole B for mid & narrow
feed deck combine adapters.
