1. Remove lower strap when hooking up to a clevis type
tractor drawbar and hitch may be added to eliminate some
of the movement of the tongue caused from positive to
negative tongue weight.
CAUTION!
THIS DRILL HAS BOTH POSI-
TIVE AND NEGATIVE TONGUE WEIGHT. NEVER UN-
HOOK FROM TRACTOR WITH BOXES UNFOLDED
AND RAISED OFF THE GROUND.
Two sizes of hitches
are available: The small hole hitch with or without the
hammer strap [1 1/4" maximum pin diameter] and the
large hole hitch without a hammer strap [up to 1 1/2" pin
diameter]. The small hole hitch is sold as standard equip-
ment. The mounting holes in the hitch have been offset so
the hitch can be turned over and bolted on in three differ-
ent positions giving you six different hitch heights for both
the single and the clevis type. On the clevis type hitch, al-
ways mount the thinner strap on the bottom. CARE
SHOULD BE TAKEN WHEN SETTING HITCH SO
TONGUE OF DRILL IS PARALLEL TO GROUND WHEN
DRILL IS IN PLANTING POSITION. Use tongue jack to
level tongue, then find closest setting of hitch to match
your tractor drawbar height.
2. Attach safety chain on tongue hitch to tractor and lock
hook securely on chain. Adjust chain length to remove all
slack except what is necessary to permit turning of the drill
& tractor.
3. The tongue jack makes it possible to raise or lower the
hitch for tractor unhooking and reconnecting. Always re-
turn jack to its horizontal position on top of the tongue.

TRACTOR REQUIREMENTS
TRACTOR DRAW BAR HOOK-UP
The combination hitch can be used as either a single strap
or clevis hitch as shown in Fig. 1 and Fig. 2.
Great Plains 3-Section Folding Drills are engineered to be
used with tractors having a standard drawbar.
To operate your Great Plains Folding Drill in most field
conditions, a tractor of 185 horsepower for 36’ drills and
225 horsepower for 45’ drills should be used.
The tractor will need 6 remote outlets {3 pair}. If your trac-
tor is equipped with only 2 pair of remote outlets and a
marker circuit is required, a marker sequence valve with
double selector is available through your Great Plains
dealer
