Install Row Extensions
Refer to Figure 27 (depicting 4.5ft drags)
A complete kit of 4 bar drag extensions may include a
combination of up to three different widths of drag
assemblies:
564-042L 4 1/2 FT 4 ROW DRAG EXT
564-044L 6 FT 4 ROW DRAG EXT
564-046L 7 1/2 FT 4 ROW DRAG EXT
See Pre-Delivery manual for drag identification.
1. Set a drag extension ( , or ) that is the same
width as an existing 12 row drag on the implement.
2. Remove and save two sets of bolts and nuts from the
drag extension:
803-019C NUT LOCK 1/2-13 PLT
802-091C HHCS 1/2-13X1 1/2 GR5
3. Align the pull tabs of the extension under the trailing
tabs of the rear-most drag bar. Make sure that the
tooth angle plates
are in the same orientation on
the drag extension as on the main drag. See
Figure 21
on page 37 for details on tooth angle.
4. Secure pull tabs with bolts and nuts .
5. Repeat step 1 through step 4 for all drag sections.
Refer to Figure 28
Move linking chains starting with the center wing.
6. At bar 12 of the linked drags, remove the teeth
803-342C NUT HEX TOP LOCK 1/2-13 PLT
891-238C HARROW TOOTH - 8 1/2" DIAMOND
securing the linking chain
564-092D CHAIN 5/16 HIGH TEST 8 LINKS
between the drag sections.
7. Re-install the teeth at row 12 without the
chain . Tighten nuts only to Grade 2 torque
specification, to avoid crushing the tubes.
8. Re-install the chain between the same drag sec-
tions at row 16.
9. To make a chain connection, remove the end set of:
803-342C NUT HEX TOP LOCK 1/2-13 PLT
891-238C HARROW TOOTH - 8 1/2" DIAMOND
