LIFT ARMS
Attach the lift arms to the wing tubes using 7/16” x 7-1/4” bolts.
Start at machine center and measure outward using the following
guide.
All measurements are to the center of the lift arms. The end lift
arm on each wing should be close to the end wheel so the section
harrows out the wheel track.
In cases where both 5-1/2’ and 7’ sections are used on the wings,
the 7’ sections are used on the ends.
SECTIONS:
Assemble 5 bar section linkage as shown in figure 4.
The sections are attached as shown in figure 3. Connect the 8-
link pull chain to the middle hole of the lift arm using a clevis pin
and hair pin. Connect the 6-link pull chain to the bottom hole of
the lift arm using a 1/2” x 2” bolt, lockwasher and nut. Position
harrow section as shown and secure using a 1/2” x 2” carriage
bolt, flat washer and lock nut to attach one chain on each side of
bracket.
Secure with heavy flatwasher and locknut. Repeat for other side
of section.
Attach the 9-link lift chain to the lift arm with a 7/16” x 2” bolt.
Attach the lift chain to the section with a 1/2” x 1-1/2” carriage bolt
inserted in the front hole.
OPTIONAL SPRING PRESSURE
To assemble the optional spring pressure to the lift arms, first in-
sert an eye-bolt through the lift arm with the eye toward the outside
of the harrow section (See figure 5). Attach other end to the harrow
section with a 1/2” x 2-1/4” bolt, lock washer and nut. Install a
bushing between the eye-bolt and section as illustrated. Repeat
for the other side of the section.
TRANSPORT WHEELS
Install the transport wheel as shown in Fig. 1. Place the transport
wheel assembly over the end section on units up to 56 ft. On sizes
over 56 ft., install over the second section or between end sec-
tions. On the 84 ft. model, install wheel between the two end sec-
tions. On the 98 ft. model, install wheel over the second section
from the end. On the 112 ft. model, install wheel between the sec-
ond and third sections from the end.
Secure with two 5/8” x 5-1/2” bolts, lock washers and nuts.
NOTE: Transport wheel brackets are made for left and right
and are not interchangeable.
IMPORTANT: The positioning of the transport wheel assem-
blies on the wing tubes of the machines is very critical in
determining hitch weight. Moving transport wheel assem-
blies forward will increase hitch weight and moving rear-
ward will decrease hitch weight. See the “Warning Regard-
ing Machines With Negative Hitch Weight” on page 1-2 for
