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, loosen the four 7/16 bolts that hold
the seed bin to the frame.
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.
