Closing Disk Option
For proper seed-to-soil contact, the closing disks
must have enough down pressure to close the
seed trench without unnecessary soil
compaction.
Refer to Figure 28
To adjust down pressure on closing disks, ratchet
spring cam to next cam height by turning head of
support bolt (1) clockwise.
Frame Height
Bean machine operating height directly affects
the working range of the row units. Initially adjust
frame height as explained under “Leveling Bean
Machine”, page 18. You can make further adjust-
ments to compensate for field conditions.
Refer to Figure 29
NOTE: Jam nut is left-hand threaded.
Make sure upper clevis (2) is in the upper mount
hole. Loosen jam nut (1) to lengthen or shorten
gauge-wheel turnbuckle.
• Lengthening turnbuckles raises bean ma-
chine and allows less row unit down float.
• Shortening turnbuckles lowers bean machine
and allows less row unit up float.
Adjust both turnbuckles to the same length and
tighten jam nuts.
After adjusting gauge-wheel turnbuckles, be sure
to level the bean machine with top hitch link.
NOTE: Lowering the bean machine increases the
risk of row unit damage on rocks or obstructions.
Seeding Rate
Adjusting the seeding rate requires the following:
1. adjusting drive speed range sprockets,
2. adjusting transmission sprockets,
3. preparing seed meters,
4. checking seeding rate.
Before setting the seeding rate, rotate the gauge
wheels. Check that seed meters, seed tubes and
drives are working properly and free from foreign
material.
