DOWN PRESSURE SPRING INSTALLATION
FOR JOHN DEERE 7000/7200/1700
NOTE: Mounting hardware included in 2960-123 bolt bag.
1. Remove the front lower parallel link pivot bolts and spacers. Do not discard the
spacers, as they must be re-used. Install spring anchor castings to the front
lower pivot of the parallel link using new longer bolts and spacers as shown.
NOTE: On John Deere 7000 the short stubs on the castings mount to the outside
and the castings mount on the outside of the parallel links, most other planters IE:
Yetter & Kinze also assemble as 7000. On John Deere 7200 and 1700 series the
short stubs on the castings mount to the inside and the castings mount on the
inside of the parallel links.’
2. Remove the front upper parallel link pivot bolts and spacers and install front bar to
the upper front of the parallel link using new longer bolts and spacers provided,
along with the existing spacers just disassembled.
3. Assemble springs and spacers to spring bar as shown in the appropriate drawing
and secure with cotter pins.
4. Lower this assembly onto the parallel links with the two middle adjustment holes on
the spring bar facing up as shown. This allows maximum down pressure
adjustment.
5. Assemble spring bar over the guide pin on the front bar and secure the ends of the
springs to the spring anchors using ¼” x 2” roll pins. It will be necessary to have
planter units in transport position to install springs, or adjust tension.
6. Insert spring adjustment pin in the desired hole on the spring bar and secure with
1/8” hairpin cotter.
7. Assemble the spring stops to the upper parallel arms with the ½” x 2” bolts and
locknuts provided. The spring stops must be assembled on the ‘inside’ of the arms
and the heads must be towards the middle of each row unit. The spring stops are
to be assembled to the rear ‘spare’ hole in the upper parallel arms and will prevent
the springs from sliding back too far.
8. Refer to ‘Troubleshooting’ page if necessary.
