WARNING
Front wheel Pull-Type Seeders have negative tongue weight
when in transport position. Negative tongue weight may cause
immediate elevation of tongue. Always be certain seeder is
hitched securely to tractor drawbar and safety chain attached
before raising. Lower seeder before unhitching.
Pull-type units are equipped with a clevis style hitch. For
proper field operation, the seeder box should be level in
field position.
1.
The mounting holes in the clevis hitch have been
offset so the hitch can be turned over and bolted at
two different hitch heights.
2.
Back the tractor draw bar up to the seeder hitch to
determine the proper hitch position.
3.
Connect hitch to the tractor using a pin of adequate
strength (minimum 1" diameter). Secure hitch pin
with a retaining clip.
4.
Your Pull-Type Seeder is equipped with a hitch safety
chain. The safety chain should be securely attached
to the seeder hitch and tractor draw bar support.
5.
Retract tongue jack until the weight of tongue is
resting on tractor draw bar.
Refer to Figure 2-4:
6.
Unpin tongue jack and pin in storage position as
shown.
Leveling Seeder Box
All pull-type, end wheel, and front wheel units should be
properly transported with seed box level front to back.
Pull-Type with End Wheel Units
Refer to Figure 2-5:
Adjust turnbuckle to level seeder by loosening jam nuts
and turning the center section. Retighten jam nuts when
level.
Pull-Type with Front Wheel Units
Use tongue hydraulic cylinder to level the seed box.
IMPORTANT: Be sure to follow “Tractor Drawbar
Hook-Up” instructions when hooking-up to a “Front
Wheel Pull-Type Seeder.
Negative tongue forces imposed with front wheels in
the raised position when seeder box is:

•
Loaded: 30 bushel box can be as high as 1500 lbs.
IMPORTANT: For the Front Wheel Pull-type option
you must install a retaining clip on the hitch pin to
prevent it from working up as the seeder changes
