Great Plains 2-Section Folding Drills are engi-
neered to be used with tractors having a standard

To operate your Great Plains Folding Drill in most
field conditions, a tractor of 125 minimum horse-
power for 24’ drills and 150 minimum horsepower
for 30’ drills should be used.
Tractor Draw Bar Hookup
Refer to Figure 2, 3 and 4
1. 1.The hitch can be used as either a single
strap, clevis or combination hitch as shown in
Figure 2 Single Strap Hitch, Figure 3 Clevis
Hitch and Figure 4 Combination Hitch.
!
CAUTION
This drill has both positive and negative tongue
weight. Never unhook from tractor with boxes Unfold-
ed and Raised off the ground.
2. When using the combination hitch, remove
lower strap when hooking up to a clevis-type
tractor drawbar. Spacers between the draw-
bar and hitch may be added to eliminate
some of the movement of the tongue caused
from positive to negative tongue weight.
Two hitch sizes are available: The small hole hitch
with or without the hammer strap (1 1/4" maxi-
mum pin diameter) and the large hole hitch
without a hammer strap (up to 1 1/2" diameter
pin). The small-hole hitch is sold as standard
equipment.
The mounting holes in the hitch have been offset
so the hitch can be turned over and bolted on in
three different positions giving you six different
hitch heights. On the clevis-type hitch, always
mount the thinner strap on the bottom.
