Tractor Drawbar Hook-Up
PS25120 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, Figure 2-3.
2. Back the tractor draw bar up to the seeder hitch to
determine the proper hitch position.
3. Connect the hitch to the tractor using a pin of
adequate strength (minimum 1” diameter). 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 from positive to
negative tongue weight.
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.
