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 455/1520/1530 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: 6732667, 7059258 and 7273017. The single-use
license is included with this document (see page 12).

PERSONAL INJURY
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 Installation
SCALE BRACKET AND LOAD CELL MOUNTING INSTALLATION
The John Deere 455/1520/1530 Grain Drill Scale Kit consists of mounting four load cells, J-Box and
scale indicator to support the seed hopper.
1. On the right side, as you are facing forward looking at the tractor,
the seed bin to the frame.
loosen
the four 7/16 bolts that hold
2. On the left side, remove the 7/16 bolts that hold the seed bin to the frame.
3. Use a jack to lift the left bin side up; use a 4” x 4” or 4” x 6” board. Support the 4” x 4” or 4” x 6” board
with the walkway and the front frame. Put your jack between the board and the bottom of the seed bin.
It is recommended the hopper be supported by two methods when installing the load cells and
brackets. In addition to lifting the hopper with a chain or nylon strap, the hopper should be supported in
the middle with a hydraulic jack or stands.
Important:
The lifting chains, bucket attachments, loader/skid steer or winch must be capable of lifting
and controlling 1000 lbs.
4. Jack up the bin 5”.
5. Install the bottom bracket with 7/16 x 1.5” bolt and 7/16 x 1.5” socket head cap screws.
IMPORTANT
:
The 7/16 socket head cap screws are mounted in the countersink holes in the lower bottom bracket.
Leave the bolts loose at this time.
6. Install the top bracket with 7/16 x 1.5” bolt and 7/16 x 1.5 socket head cap screw.
IMPORTANT
: The
7/16 x 1.5” socket head cap screws are mounted in the countersink holes in the upper bracket. Tighten
the 7/16 tapered bolts first and then the 7/16 standard bolts.

7. Slide the load cells into the sockets on the bottom bracket. Slide the load cells all the way into the
socket. Stop when the load cell cord is up against the socket. (Load cells with 11 ft cable are in the
rear.)
IMPORTANT
: Decal must point
DOWNWARD
. See Detail A.
8. Lower the seed hopper
down slowly and be
careful not to cut the load
cell cord next to the
socket on the bottom
bracket. Lower the
hopper until the top
bracket socket lines up
with the bottom load cells.
Slide the load cells into
the top socket and install
3/8 clevis pin and cotter
pin.
9. Let the jack down. Do not
tighten the bottom bracket
bolts at this time.
10. Repeat steps 2 – 9 for the right side.
IMPORTANT
: For JD455 grain drill, disconnect the drive shaft
bearing holder, drive chain and clutch arm.
11. When both sides are completed, tighten the bolts on the bottom bracket. Tighten the tapered bolts first
and then the standard hex head bolts.
Clutch Arm Updates
To make room for the load cells, the hopper was raised upward by approximately 4”. As a result, the drive line
clutch must be modified. There are two types of updates depending on your grain drill series.

Scale Bracket and Load Cell Mounting Installation
JD455 Clutch Arm Updates
1. Mount the drive shaft bearing
holder provided with the kit.
Weld the bottom bracket to
the drill frame when the shaft
looks straight.
2. Install the chain tightener
provided with the kit (you may
need to shorten the chain).
3. Install the new clutch drive
arm. Drill a hole in the arm
so the clutch is disengaged
when the drill is up and
engaged when the drill is
down. The length extended
on the clutch arm is the same
distance that the seed bin
was raised, because of the
scale system.
JD1520/1530 Clutch Arm Updates
1. Switch space (number 1) with gear (number 2).
2. Remove bolts on
end bearing
holder and slide
main shaft
(number 3) away
from tank.
3. Remove sprocket
and role pin, then
slide the bearing
on first.
4. Install bearing
holder close to
the inside of the
sprocket.
5. Line up the chain
so the sprockets
will be straight
with each other.
Make sure the
shaft does not
touch the tank.
6. A hole will have to be drilled in the gusset on the frame to get the U-bolt to go in (number 4).

Junction Box Mounting
JUNCTION BOX MOUNTING
The junction box is water resistant, not water-proof. It should be mounted to avoid submersion during wet
weather and to avoid physical abuse. The junction box can be mounted on the front or rear of the drill,
planter or seeder. All load cell cables must reach the J-Box. Install by removing the double sided tape
backing and apply to cleaned 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 as shown above. See instructions below.
5. Install terminal block into the J-box as shown (location
not important).
6. Tighten nuts on the water-tight 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
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.
DRILL 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 #145015 and calibration #14000 (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.
Power Cable Connections:

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.
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.
If further assistance is necessary, please call Digi-Star, LLC at 920-563-9700.
NOTE
NOTE
: The clutch arm needs to be on the back of the clutch to work properly.
