Sections with 9/16” diameter teeth:
See assembly instructions on page 2-10 for installation of sections. Attach two long lift arm exten-
sions to the lift arms on the first section to left of center. Extensions for adjoining sections must be
alternating lengths (short and long).
See Figures 3 & 4 (Page 4-12) for alteration instructions
of two tines above knuckles.
NOTE: Do not use 8HD6150 (Angle, tooth stop – shown
on page 2-11). Cut off the front outside teeth as shown
to prevent interference with knuckles in transport position.
PIVOT ARMS
Attach short pivot arms to short lift arms and long pivot
arms to long lift arms with 1/2” X 5” cap screws and lock
nuts. Do not overtighten lock nuts. Pivot arms must
swing freely. Install pivot arms with knuckle pivot stop
up in field position.
SECTION BRACES
Sections with 3/8” diameter teeth:
Attach angle braces to lift arms near packer pivots using
3/8” u-bolts and hardware. Use 33” long braces over lift arms between harrow sections (except over
knuckles and end sections). Use 63-1/4” long braces over outside three lift arms.
Sections with 9/16” diameter teeth:
Attach tube braces to lift arms between sections (as shown in Figure 4) using 1/2” u-bolts and hard-
ware. Locate braces near extension splice. Insure that brace location does not interfere with section
adjustment or coil travel. Do not install tube braces over knuckles.
PACKER SECTIONS
Attach pull frames to pivot arms with 1” X 6” pins. Secure with flat washers and cotter pins. Insert
and secure adjustment arms in the following
settings:
*Machines with 9/16” diameter tines:
Add 8C4090 counter balance to left side adjustment
arm of left center coil. Replace 8HD0510 with
8HD0520 below all sections. Trim inside of
front pipe of first section on left wing at 3-1/2”
from bolt hole center to end of pipe.
Attach left hand coils to long pivot arms and right hand coils to short pivot arms. Secure pillow block
bearing to adjustment arm with 1/2” u-bolt and hardware. Center coil and secure bearing to coil shaft

TRANSPORT WHEELS
Locate transport wheel assemblies over end harrow section on 30 to 40 ft. machines with pivot tube
in higher position. Install between end section and second section on 48 to 60 ft. machines with
pivot tube in higher position. Install over second section on 70 ft. machines with pivot tube in higher
position. Secure with 7/8” u-bolts and hardware.
Transport axle “toe-in” can be adjusted with outside stop set bolt (8X0665, page 4-5). Adjust inside
stop bolt 3/8” away from pivot plate when resting on outside stop bolt. This adjustment will allow
transport wheel to pivot inward while unfolding. Double lock stop bolts with 3/4” jam nuts provided.
