INTRODUCTION
Congratulations on the purchase of your new Digi-Star Grain Drill Scale System. This scale system is
specifically designed to weigh the seed hopper on a John Deere 750/1560/1590-20 ft Grain Drill. The scale kit
can be used to record and monitor seed weight going into or out of the seed hopper.
This scale system is covered by the following US patents: 6,732,667; 7,059,258; 7,273,017; 7,357,087;
7,448,335; 7,523,710; 12/427,915; 6,572,257; and 7,454,304. The single-use license is included with this
document (see page 13).

and carefully read the message that follows.
Important!
Charging Battery and Welding
Disconnect all cables from the weighing indicator before charging the battery or welding on the machine. If
cables are left connected, the weighing indicator and connected load cells could be damaged.
Important:
Do not weld near indicator, load cells or cables; remove from area to be welded. Place ground
close to area to be welded to prevent current from passing through electronic parts.

Scale Bracket and Load Cell Mounting Installa tion
SCALE BRACKET AND LOAD CELL MOUNTING INSTALLATION
1. Remove the cat walk and drive chain off of both the ten foot seed bins.
2. On the left side of the seed bin, loosen the four bolts that hold the seed bin to the frame. DO NOT
remove bolts. Repeat the process on the right side.
3. Remove the bolts on the middle of the two seed boxes. The access hole will need to be cut in order to
access the back bolts.
Access Hole
4. On the inner frame on the left and right sides (that runs under the seed bin) place a jack between th e
frame and seed bin. Lift the middle of both seed bins up about 2-3”. Ins tall the middle bracket. Do not
tighten bolts.
Important:
The lifting chains, bucket attachments, loader/skid steer or winch must be capable of lifting
and controlling 1000 lbs.

5. Install the front and back middle load cells with the 2-1/4” clevis pins. The load cell’s arrow must be
pointed up (located on the end of the load cell). Two of the load cells are marked with short cords for
the center of the drill.
6. Next, install the rear middle bracket. Let the seed bin down to about 1”. Use the 2-1/2” x 3/8” clevis pin
to hold the weigh-bar in place. The pin should be in the middle of the 1/2” hole.
7. Install the front middle bracket. Install the 2-1/2 x 3/8 clevis pin the same as the rear bracket. Leave all
bolts loose.

8. On the left side, remove the bolts that hold the seed bin to the frame.
9. Lift the seed bin up about 2-1/2” on the left side.
The hopper can be lifted
by wrapping a nylon strap
or chain around the
hopper end. (Left side of
hopper shown.)
10. Install the middle bracket under the seed bin (do not tighten bolts yet). See the diagram of the John
Deere Grain Drill Scale Kit.
11. Install the front and back load cell with the 2-1/4” x 3/8” pins. Make sure the load cell arrow sticker is
pointed up.
12. Let the seed bin down to about 1” and slide the rear bracket on. Use the 5/8” x 8” bolts in the front 2
holes. Use the 2-1/2” x 3/8” clevis pin to hold the load cell in place. Make sure the pin is in the middle
of the 1/2” hole. Note: The rear step grip is installed between the rear bracket and the step bracket
already on the grain drill. Do not tighten the bolts.
13. Install the front bracket with the bolts left from the rear bracket. Use the 2-1/2” x 3/8” clevis pin to hold
the load cell in place. Make sure the pin is in the middle of the 1/2” hole.
14. Make sure the middle, front and rear brackets are straight with each other.
15. Remove the bolts on the right side that hold the seed bin to the frame.
16. Repeat steps 9 to 14 on the right side of the drill.

17. When both sides are done, the brackets should stand straight; neither should lean. Tighten the bolts on
all brackets in the following order:
st
: Tighten the middle bracket
1
nd
: Tighten the rear bracket
2
rd
3
: Tighten the front bracket
18. Reinstall catwalk. Trim catwalk so that it does not interfere with middle bin support.

19. Bolt the readout in the cab with the bracket or mount the bracket on a stand in the front of the lift
cylinder.
20. Install power cord to a 12 volt negative ground battery (white or red is positive, black is negative).
Install the J-box on the seed bin in the middle of the drill
21. Route the load cell cords so it will not be bounced or pinched by anything (see Mount Junction Box
instructions).
22. Lengthen the drive chain with provided chain links. DO NOT TIGHTEN CHAIN. Leave the chain loose
enough so it is not pulling down on the seed bin.

Junction Box Mounting
JUNCTION BO X MOU NTIN G
The junction box is water resistant, not water-proof. It should be mounted to avoid submersion during wet
weather and to avoid physical abuse. Install the junction box on the front middle of the drill, by removing the
double sided tape backing and apply to cleaned planter surface.
Connect Load Cell and J-Box Cable
1. Route front and rear load cell cables to J-
box location. Make sure they are not
bound or pinched. Cable tie (customer
provided) load cell cables in place.
2. Insert load cell and J-box cables through
each of the water-tight strain-reliefs.
3. Remove each terminal block from the J-
box.
4. Connect wires of the same color to the
same terminal block. See instructions
below.
5. Install terminal block into the J-box as
shown (location not important).
6. Tighten nuts on the water-tig ht strain-
reliefs.
7. Assure that gasket is properly installed in
the cover.
8. Attach cover using 4 screws (provided).
Installing wires into Terminal Block
1. Open levers 90º to locked position.
2. Insert individual wires into terminal.
3. Close lever.
4. Tug wire to assure solid connection.
Note: Wire strip length is 7/16” (11mm).

INDICATOR MOUNTING
The scale indicator can be mounted in the tractor cab or on the drill with swivel mounting pack (406081). Two
cables must be connected to the indicator bottom panel, J-Box and power cables. Refer to Indicator Manual
D3831-US for details of indicator mounting options and connection of power cord.
PLANTER MOUNTING
1. Bolt the readout in the cab with the bracket, or mount the bracket in the front of the lift cylinder.
2. Install power cord to a 12-volt negative ground battery.
3. Route J-box cable to indicator and install to indicator bottom panel.
4. Program indicator with set-up #145022 and calibration #21000 (see Indicator Manual)
INDICATOR MOUNTINGS
TRACTOR CAB MOUNTING
Power Connection:
The power cable should be connected directly to a vehicle battery or regulated power supply. The scale end of
the power cable is attached to the J901 connector located on the bottom panel of the indicator.
Connect the RED wire from the power cable to +12 VDC and the BLACK wire to GROUND. The indicator is
fused internally at 4 amps.

Trouble Shooting
TROUBLE SHOOTING
How to Check the Drill Scale after Installation
For the first test, lift the drill all the way up, to a level area. Put 200-250 pounds of weight on the right side,
then compare it to the left. Both sides should be within four to six pounds of each other.
•
If the weight is not within the four to six pound range, the drive chain might be too tight or the clutch is
binding. Loosen the chain and check the weight again.
•
If loosening the chain does not fix the problem, you must remove the clutch arm, and then check the
weight on both sides.
properly.
The second test is to lift the drill to a level area and zero the scale. Lift the drill up and down two to three times,
checking to see if the scale zeros out. Each time the scale is in the up position, it should be within four to six
pounds. If not, remove the clutch arm and repeat the test. If this solves the weigh problem, the clutch is
binding or it needs lubrication.
properly.
If further assistance is necessary, please call Digi-Star, LLC at 920-563-9700.
