Disc Gang and Spray Shield
Installation
IMPORTANT
Read all safety precautions at the front of the section
before attempting any of the following procedures.
1. Roll correct size disc gang assembly under frame
and wing assembly. See Table 3-5 for disc size and
location.
IMPORTANT
Disc gangs without flat coulter blade are used on
main frame. The flat coulter blade should be to the
outside of the machine.
2. Install disc gangs on main frames using 4 and 5 hole
disc mount plates, u-bolts, 5/8-11 x 5-1/2 hex head
cap screws, and hex lock nuts (See Figure 3-11.)
IMPORTANT
The distance between the disc gang nuts at center of
unit should be 1-1/2".
3. Install disc gangs on wings using 4 and 5 hole disc
mount plates, u-bolts, 5/8-11 x 5-1/2 hex head cap
screws, and hex lock nuts.
IMPORTANT
The distance between last blade on main frame and
first blade on wing should be 7-1/2".
IMPORTANT
Disc rod and slotted nut should be tightened to a
torque of 1200 ft. lb. This is equivalent to a 200 lb.
man standing at the end of a 6 foot long wrench.
Install spacer washers at end of disc rod as required.
4. Tighten 5/8-11 x 2-1/2 hex head cap screws
attaching 5 hole plates to spring shank disc mounts.
Now tighten 5/8-11 x 5-1/2 hex head cap screws and
u-bolts. Be sure 5 hole plate contacts frame evenly
and bearings are square on disc rod when tightening
or unnecessary bearing load can occur.
IMPORTANT
Last disc blade on all main frame disc gangs are not
equipped with a scraper.
5. Attach spray shield adjustment bracket to frame, as
shown for your model size, using u-bolt, bracket
clamp, and 5/8-11 hex lock nuts. These brackets are
attached to frame as shown to incline the shields
toward the middle of the machine and carry soil back
to center of the main frame (See Figures 2-1
through 2-7 for location on frame).
6. Attach spray shield to adjustment bracket, as shown
in Figure 3-11, using 5/8-11 x 2 hex head cap screw,
backup plate, and hex lock nuts. Shields attached in
position shown in Figure should be set to allow the
machine to operate from 3-5 inches deep. Tighten all
spray shield screws and u-bolts.
