Installation Instructions 1
Small Seeds Option
5- and 6-Foot Drills
Used with:
• 3P500, 3P600
• 605NT, 606NT
• 3P605NT, 3P606NT
General Information
These instructions explain how to install a Small Grass
Seeds (SGS) assembly on a compatible drill.
The Small Seeds option adds the capability to meter the
smallest of seeds at rates more precise than using the
main seed box for those seeds.
These instructions apply to an installation of:

Before You Start
Compatibility
Refer to Figure 2
1. Make sure that the drill is a compatible model for the
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.
Order one of:
67
838-207C DECAL 605NT
838-203C DECAL 3P605NT
Inventory
3. Make sure all parts are present. Remove all parts
and any packing material from inside the new Small
Seeds box.

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:
85
802-007C HHCS 5/16-18X3/4 GR5
93
804-009C WASHER LOCK SPRING 5/16 PLT

WARNING
!
Negative tongue weight hazard:
Lower the openers on pull-type drills. The weight of a person
on raised openers can cause an unhitched tongue to fly up,
causing a fall and possible serious injury.

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.

Check System Function
72. Lubricate new chains.
73. Hitch tractor.
74. Raise and lower drill, checking for excess tension or
slack in new seed hoses.
75. Raise drill. Exercise the calibration procedure for
the drill, checking for correct operation of all new
sprockets and chains.
Small Seeds Operation
Make sure you have the latest Operator and Seed Rate
manuals for your drill. Details of Small Seeds box adjustment and calibration are covered in the Seed Rate manual.
Small Seeds rate is set entirely by the rate handle on the
new SGS box and is unaffected by the Drive Type setting
used for the Main seed box.
Unless also metering from the Main box and/or Native
Grass box at the same time, prevent wear by disconnecting chains, or reduce Main box wear by setting the Drive
Type to 1.

Small Seeds Maintenance
Chain Installation
Whenever mounting a chain, make sure the clip at the
removable link is oriented to minimize snags.
Refer to Figure 25 (arrow shows chain direction)
Install clip with open end facing away from direction of
chain travel (striped arrows in routing diagrams).
Chain Slack
Check slack within the first 8 hours of operation and
tighten idlers as necessary.
Refer to Figure 26, which, for clarity, greatly exaggerates slack, and omits the idlers.
1. Measure the span for allowable slack:
Locate the longest span of each chain (usually the
span which does not run through the idlers).
2. Determine the ideal slack:
Long chains (over 36in/91cm):
Vertical short chains:
Horizontal short chains:
3. Measure the slack by acting at a right angle to the
chain span at the center of the span, and deflecting
in both directions. The slack is the distance of the
movement.
4. Adjust the idlers for ideal slack.
