kit. See table on page 1. The full model number for
the drill is found on the serial number plate.
2. If the drill is a model 605NT or 606NT, you may want
to replace the ‘606 decal in the kit with the correct
decal for your drill. It is not necessary to have these
decals on hand during the kit installation.

Comprehension
4. Review these instructions. Make sure the installers
understand where each part or assembly is
installed, and what tools are required for the task.
Note: Illustrations in this manual, based on the parts
manuals for this family of drills, may show
exploded views that are fully disassembled. Rely
on the instructions for required disassembly and reassembly steps.
Pre-Assembly Preparation
Tools Required
• updated drill Parts Manual (see page 1)
• suitable tractor for positioning and lowering drill
• blocks for securing transport tires if drill will be
unhitched for the work
• two people or a hoist - several longs parts are suitable
for unassisted single-person removal/installation
• chain lube
• basic hand tools, including:
snap ring pliers

Work Location
5. Move the drill to a location with:
• room to maneuver large parts around it,
• access to tractor or hydraulic power,
• adequate illumination, and;
• clear surface beneath for recovery of any falling
or dropped parts - if the surface is not clear, have
a tarp or drop cloth available.
6. Park the drill per the instructions in the Operator
Manual.
7. Lower the drill and the openers
8. Shut off tractor if left hitched.
Remove Existing Parts
Refer to Figure 3
9. At each grab handle on the back corners of the rearmost seed box, remove and save two sets (four sets
total) of:
88
802-203C HFSS 1/2-13X1 1/2 GR5
92
803-169C NUT HEX FLG. LOCK 1/2-13 PLT.
and two:
81
119-190D HANDLE
These are re-mounted on the new SGS box at
step 15 on page 4.
Note: Existing hardware may vary slightly from parts
called out in these instructions. For example,
instead of flange nuts, there may be separate
washers and there may be a 133-045D strap. Note
such changes, so that parts are correctly reinstalled.
Refer to Figure 4
Step 10 is required only for drills with existing Native
Grass boxes, but is recommended for all drills, to clear
access for mounting the SGS box.
10. At the SMV placard remove and save two sets:

Install 3P500/3P600 Shaft and Sprockets
Refer to Figure 10
22. Select the shaft in your kit, one of:
14
133-037D SGS/AUXILLARY DRIVE SHAFT
133-052D 5’ SGS DRIVE SHAFT
and one each new:
40
808-170C SPKT 40B17 X 3/4BORE W/KW&SS
38
808-100C SPKT 40B22 3/4B W/K.W. &SS
As necessary, back out the set screws in the
sprockets so that the sprockets can slide freely on
the shaft.
Note: The shaft has keyways of different lengths on each
end. The end with the shorter keyway is the right
end. The end with the longer keyway is the left
(gearbox) end. The shaft may be inserted in the
drill from either side, as long as the sprockets are
correctly oriented. These steps use the left side.
Note: The sprockets are not symmetrical. For ease of
future maintenance, the set-screw side is oriented
to drill center.
23. Insert the right (short keyway) end of the shaft
through the new bearing .
Note: Keys are installed at step 31 and step 35.
24. As the shaft passes behind the gearbox , add the
22T sprocket , with the set screw side facing
right.
