Tractor Draw Bar Hook-Up
Refer to Figure 3, Figure 4 and Figure 5
1.
The hitch can be used as either a single strap, clevis,
or combination hitch.
Refer to Figure 4
2.
When using the combination hitch, remove lower
strap when hooking up to a clevis-type tractor
drawbar. Spacers between the drawbar 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
inch maximum pin diameter) and
• the large hole hitch without a hammer strap (up to
1
1 ⁄
2
inch 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. SET 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.
3. 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 and tractor.
4. The tongue jack makes it possible to raise or lower
the hitch for tractor unhooking and reconnecting.
Always return jack to its horizontal position on top of
the tongue at the pull bar slide stop.
