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

properly transported with seed box level front to back.
